That's a lovely scrollbar!

Lots of stuff is happening at MSFT right now. Windows 8.1 is around the corner (did you download the 8.1 Preview?) and development is still happening on Visual Studio 2013.

UPDATE: Don't like the Light Theme? The old VS2010 Blue Theme is back, use it instead. Use whatever Theme relaxes you and whatever text colors make you happy.

Change your theme

Use whatever colors make you happy. Here's 2013 with the 2010 theme.


Anyway, the ASP.NET and Web Tools team is hard at work on VS 2013 with Web Tools. Remember that the tooling for ASP.NET was pulled out of VS in 2012 and remains an "out of band release." This gives us more flexibility than we had before and will let us get more time to put features in and fix bugs than some groups.

Truth is, the next 4-6 weeks is when we need to be fixing bugs and finding any edge cases or weird stuff. For example, we know that Glimpse doesn't work well with Web Forms and FriendlyUrls. We are actively working on that now.

Download Visual Studio 2013 (and ASP.NET with Web Tools) while your feedback still matters.

What we need from you is bugs and feedback. You can put suff on:

Should you install VS2013?

I have it installed on all my four machines and nothing has broken yet.

Since Visual Studio 2013 installs side-by-side with VS2012 and VS2010, if you already have .NET 4.5 and VS2012 it's not that risky to install VS2013. This has a Go-Live license and includes .NET 4.5.1.

RISK: If you have only VS2010 and .NET 4.0, .NET Framework will upgrade your .NET 4.0 to 4.5.1. If you are shipping to a server with .NET 4 you'll likely be OK, but you ARE taking a risk, so don't use a work machine you deeply care about to test on if you also have to ship .NET 4.0 only code.

BENEFIT: That said, anything that breaks under 4.5.1 we DO want to know about. Meaning, if ASP.NET 4.5.1 breaks your ASP.NET 4 app we need to know and we will only find out if you test. But, don't use the only machine you have to work on every day if it's all you have to ship with.

We would REALLY appreciate folks testing ASP.NET 4.0 apps to run them up ASP.NET 4.5.1 and find bugs. It's that scenario that is the most interesting.

What do you need to get?

All this works in the Free Web Express version so you don't need to have a paid copy of Visual Studio to install VS2013.

Useful VS 2013 features

There's lots of new stuff (check the ASP.NET Release notes) but here's just a few highlights:

Edit and Continue for 64 bit applications - In VS2010 and VS2012, the edit and continue option is disabled by default when creating a new web application project. In VS2013 preview, we turned it on by default. You can find this option on the Web tab in the web project’s properties window.

One ASP.NET with Updated Templates - You'll see this in my talk at BUILD on What's New in ASP.NET and Visual Studio 2013. The dialog isn't done, but we are moving forward with lots of new improvements. Also, ASP.NET includes Twitter Bootstrap out of the box as the default template.

Extensible Scaffolding Framework with new Web Forms Scaffolds and improved MVC scaffolders. You can now enable an ASP.NET app for MVC or Web API and get all the required packages via NuGet. This moves us towards One ASP.NET. There is no "MVC Project Type" or "Web Forms Project Type." There is just one and you can mix and match as you like.


Entity Framework has Async Query and Save support, better POCO support, improved perf, connection resiliency, and Code First mapping to Stored Procedures (and more).

VS tooling enhancements - Editor enhancements, Browser Link. There's an all-new HTML editor that understands HTML5 at the core, lots of stuff there but you'll be most impressed with Browser Link (name will likely change)'s a bi-directional link between ALL running browsers and Visual Studio, powered by SIgnalR.


So you can do this:

Updating two browsers and an iPhone from VS2013

New Authentication & Identity Model - Auth and ASP.NET Identity is being fixed and rewritten with extensibility in mind. That includes the existing support for Google, Facebook, Microsoft ID, Twitter, Open Auth in general as well as Windows Auth and Windows Azure Activity Directory. (That last one means you can run an intranet app in Azure and authenticate it against your company's existing Active Directory! That means cloud-hosted intranet apps.)


New Web API and SignalR functionality - Web API now supports Portable Formatters that can be shared on client and server and you can create clients that work on Windows Phone and Windows Store apps. Web API is also updated to support easier Unit Testing of Controllers. Web API also supports AttributeRouting via an OSS contribution from Tim McCall, and CORS via an OSS contribution from Brock Allen. ASP.NET Web API also supports OWIN and OWIN hosts (it can be hosted outside IIS or in your own Service). SignalR now has iOS and Android support via MonoTouch and MonoDroid in Xamarin tools! SignalR also includes a Portable .NET Client.

We are also (quietly) making other changes moving towards bigger ones, including removing the "Windows-only" Restriction for the ASP.NET Project codenamed "Katana" that will be a big part of the next version of ASP.NET and is a part of the plumbing of this release of ASP.NET as well.

A few of my favorite small Non-ASP.NET specific features are viewing method return values in the debugger (duh!)

Return Values

and "Peek Definition" which lets you look at a method definition without opening the file.

Looking at a method definition without opening the file

Also, the return of "RockScroll" in the scrollbar:

That's a lovely scrollbar!

Consider also getting the newly open source "Web Essentials" - This is our "unofficial Labs" extension where we try crazy stuff. We hope you dig it and even better we hope you help us make it all better.

Initial Impressions - Intel Haswell 4th Generation Developer Prototype Ultrabook

July 29, '13 Comments [30] Posted in Reviews

Haswell Intel Prototype

I've reviewed Intel Ultrabooks before that were sent by the software development team at Intel. I review them from a software developer's point of view, so I'm pretty hard on laptops. I want them to be fast, light and fast. They should put up with a development environment being open most of the day, lots of compiling and some virtual machines for good measure.

Last year I looked at the 3rd gen "Ivy Bridge" ultrabooks:

After the Ultrabook experience, I replaced a Lenovo W520 with a Lenovo X1 Carbon Touch as my primary machine. My primary beef with the X1 Carbon is its screen resolution, a barely passable 1400x900, but everything else (plus it's just over 3 pound weight) keeps me using it. However, I get about 5-6 hours typing on the X1 but about 4 hours of "hard work" which just isn't enough considering I'd like to sit AWAY from an electrical outlet for once. If the X1 Carbon Touch had a better 1080p (or better) screen and Haswell, it could be the perfect PC. But do I really need Haswell?

All Ultrabooks are Thin Now

From The Verge, Intel has made some bold statements regarding the Haswell generation:

Intel's been branding the new processor tech as its "largest generational leap ever" with "the biggest performance improvement ever in battery life," as Intel's executive VP of sales and marketing Tom Kilroy boldly stated at Computex's opening keynote speech. The superlatives don't stop there: Navin Shenoy, vice president of the company's PC Client Group, told VentureBeat that "it’s the complete reinvention of the computer as we know it."

imageIntel folks are also saying things like "we can look forward to a 50 percent increase in battery life in the coming wave of devices, with no loss of performance."

So you'll forgive me if I have high expectations. I want this laptop generation to do nothing less than blow my mind.

The software development department at Intel has sent me an Intel Prototype Haswell Ultrabook to review, from a developer's perspective. it's a "no-name" brand (it says Intel on the outside) and it will never be sold. It's a reference hardware example, as it were. I'm not looking to review it as the Ultimate Haswell Laptop, rather as an example Ultrabook with the characteristics I would hope to see in other vendor's Haswell systems.

I will do an in depth review after a month or so of using this, but here's my initial impressions after using this Haswell Laptop exclusively for two full days of actual work.


Three pounds, baby. That's the standard for nice laptops now. If it's five pounds, it's too heavy. This is a lovely size and a lovely weight. The best part about this Ultrabook is that it's 3.5 lbs and it has a 1080p screen. YES! That's almost enough for me to start using it full time over the Lenovo Carbon X1 Touch. Air-sized is the new size. If it's not this size then I'm not interested in it.


While this is a prototype that will never be produced, it is definitely nicer than the Ivy Bridge I looked at last year. That one had a lousy keyboard and a nightmare trackpad that has since broken. (My wife can no longer "left click" with that Intel Prototype. This Haswell 4th gen has stepped up the casing part of the hardware, at least, considerably. Remembering that the insides are presumably what this device is aiming to showcase, regardless, the touch pad on this device is WAY better than my X1 (whose touchpad I despise with the heat of a thousand suns) and the keyboard, while it doesn't have Lenovo's legendary quality throw, is still comfortable and fast.

This machine is a matte, almost gunmetal black, with light but firm plastic housing. The major fail is the weak/flimsy power connector, but that's a small complaint. I would also have preferred dedicated page up/down buttons. Otherwise, it's a pleasant and appealing housing.

UPDATE: Sorry, of course, it has a touchscreen, as all Ultrabook's do, by spec definition. It also has a 1080p screen.


Setting this machine up from initial boot to a usable machine including Office 2013, Visual Studio 2013 and Windows 8.1 to just 5 hours, working at night watching TV. Mostly it was "next, next, next, finish" as the hard drive light blinked. Part of this is due to the speed of the machine, and part of it is due to newly re-written setup programs. With Office 2013's Click To Run I had Word running in 10 minutes, and VS2013 Pro Preview running in 30. Windows 8.1 took a few hours, and the rest of my developer tools were installed with Chocalatey (apt-get for Windows).

While I wasn't initially impressed with this Ultrabook having only 4 gigs of RAM and an i5 processor (Id' have preferred 8 gigs and an i7), I really haven't noticed a speed difference (yet) against my 3rd-gen i7 Lenovo X1 Carbon. I will do more profiling later to understand the characteristics of this machine and how it affects compilation and app debugging performance.

Battery Life

I have mixed feelings about this. I think the hype machine has us all in its grips. I keep hearing "12 hour battery life" and "all day battery life." But of course I realize that intellectually this means "lower the brightness and watch a movie that has the GPU do all the work and don't touch the laptop all day battery life." It's not "work really hard and compile and run VMs and Outlook and Visual Studio" battery life.

That said, I worked for 6.5 hours before the battery died. It wasn't 12, and it wasn't 10. It was nearly 7 and the brightness was at about 70%. I'm going to wait a bit and do some more formal benchmark. Yes, it's 50% more battery life than the pathetic 4 hours I get now, but it's not all day. Still, the hype machine. I am withholding judgment because it's clearly BETTER, and it's just been a few days.

Disclosure of Material Connection: Intel sent me this Haswell Ultrabook in the hope that I would review it on my blog. Regardless, I only recommend products or services I would use and think you would find useful. This opinions are mine and mine alone as is this entire post. I am disclosing this in accordance with the Federal Trade Commission’s 16 CFR, Part 255: Guides Concerning the Use of Endorsements and Testimonials in Advertising.

Choosing the right Portable Power Phone/Tablet/Gadget Battery Charger

July 26, '13 Comments [17] Posted in Hardware | Reviews
Sponsored By

microusb-vs-miniusb[1]I travel a lot and I've talked about the importance of having power while on the go. I carry a small Four Outlet Mini Power Strip, for example, as well as an all-in-one travel plug adapter. I like tools and gadgets that solve more than one problem and/or have multiple-functions.

Until phone and tablet batteries batteries can last for a day of solid use, I also carry a portable battery charger. In fact, I have been testing a bunch over the last few months in search of the Perfect Portable Battery Charger. Spoiler Alert, it doesn't exist yet, but each of these chargers has one of those characteristics.

What do I want? I want a 8000mAh or greater portable charger that weighs less than a pound, has a USB port. It should support a full 2A output for iPads or large tablets, but at LEAST 1A for phones. Bonus points for built in cables for iPhone and micro USB. It should have Solar for emergency charging. Bonus points if it can charge two phones at once, or at least take a 2A load. The fewer dongles or adapters I need to carry, the better.

NOTE: For reference as you read, here's mini-USB vs micro-USB using a photo from PowerLet and Rob Jackson.

What kind of charger do I need?

As you look at these devices and their Pros and Cons, ask yourself these questions:

  • How many times will I need to charge a single phone in a day?
    • Look at your phone's battery and see if one of these batteries will charge it once, twice, or ten times.
  • How large a battery do I want to lug around?
    • Some of these are the weight of your phone, one over a pound and a half. You WILL notice that.
  • Do I live somewhere with a lot of sun and not a lot of outlets?
    • Consider a solar charger, especially if camping (or urban camping)

WakaWaka POWER Smartphone Charger

That black part isn't a phone, that's the battery and on the side is a Solar Cell. The WakaWaka will charge in sunlight in about 8 hours, or in about 4 hours when charge it using micro-USB input.



  • Charges with Solar if needed
  • Extremely light, less than half a pound (200 grams!)
  • Flashlight with several brightness levels, good for camping
  • Small company, supports micro-finance and charitable giving


  • Only a 2200 mAh Lithium battery.
    • NOTE: Given that an iPhone 4/4s battery has 1420/1430 mAh battery this will give you about a single charge and a bit more. This device would be great with a 6000 mAh battery.


myCharge RFAM-0007 Portable Power Bank 6000

This simple and light charger charges with whatever micro-USB AC adapter you already have. It's claim to fame is the three built in cables for charging.



  • Built in old-style iPhone cable. Built in mini- and micro-USB cable.
  • 6000 mAh, very light.


  • Built in cables are wonky. My iPhone one has failed and no longer charges. I can still charge via the one USB port.
  • In my experience it's power drops off FAST. Feels more like a 2500 mAh device.

Yell BPS66 6600mAh Dual USB Energy Bar

This weirdly shaped battery is a full 6600mAh and weighs only 180 grams (well under a half-pound.) It has a mini-USB in for charging and two USB ports for output. It comes with 8 little adapters, but I haven't used any of them. I just use what came with my phone. It will also charge a large iPad which is a great plus. Charges in about 9 hours.





  • Very small and extremely powerful
  • Inexpensive given how much power it packs.


  • Still needs a mini-USB charger, preferably one that puts out 1A or more.

i.Sound Portable Power Max with 16,000 mAh

Ok, TO BE CLEAR, this thing is a BEAST. It weights 1.4 pounds, almost half what my Ultrabook laptop weighs, but - it puts out an obscene 2.4A if need be and can charge as many as 5 small phones at a time. It adds over 24 hours more usage to an iPad with a 16000mAh battery. This is a great overnight charger.



  • 16,000 mAh. There's nothing else that packs this much power. Charges an iPhone 10 times.
  • Up to 6 devices (if you use their splitter, otherwise 5)
  • Flashlight


  • Requires a proprietary AC charger - Don't lose it!
  • Heavy as heck.

PowerTrip 6000mAh with 50mA Solar Panel

This is a nice charger that plugs right into the wall. The solar panel is very small and will top it up a little in a day of full sunlight, although I've never been able to full the battery only on solar. It's the built in AC that sets it apart.



  • Built in US AC plug. Just plug the whole charger into the wall. Big win.
  • 6000 mAh, 1.5A output.
  • Small solar panel built in.
  • Comes with three little 6 inch cables for mini, micro and Apple, useful.


  • Expensive and hard to find, about $100
  • Just one USB port

The impact of a compliment

July 24, '13 Comments [53] Posted in Musings
Sponsored By

This is the beginning of a great compliment. Here, the President is speaking about the Attorney General of California:

You have to be careful to, first of all, say she is brilliant and she is dedicated and she is tough, and she is exactly what you'd want in anybody who is administering the law, and making sure that everybody is getting a fair shake.

Here's where it goes too far.

She also happens to be by far the best-looking attorney general in the country.

Is it a gaffe? Is it a nightmare? Is it tacky or inappropriate or any of a dozen other adjectives? Perhaps. That's not the point. It's simply not necessary and it's completely beside the point. This happens every day and it happens often in computing and technology contexts.

How you look is a combination of things, not the least of which being a genetic roll of the dice that you can't control. How you are, how you conduct yourself and how your work is perceived by your peers is absolutely under your control. And it is from this place, where your merits lie, that compliments spring.

When you compliment someone in a work or professional environment solely on their looks you are minimizing years of hard work, struggle and mental effort.

I like compliments as much as the next person, but it's important to not conflate personal compliments ("What great shoes!") with professional compliments("What an amazing slide deck!).

I would not like to see a comment like "Watch the kind (and well-dressed and hot) Scott Hanselman presenting on HTML5."

I'd rather see "Watch this ruthlessly competent presenter talk about HTML5."

You get the idea. Compliments to other developers should always be gender non-specific like "ruthlessly competent" or "bad ass." If someone is good at their job, you can always say "you're really good at your job." No need for extras.

Too sensitive? No, this is simple. Compliment the work and the person's effort in the creation of that work.

Your favorite presenter's outfit, hair, makeup (or lack of all three) didn't make that code run.

If you're not using Glimpse with ASP.NET for debugging and profiling, you're missing out

July 20, '13 Comments [40] Posted in ASP.NET | ASP.NET MVC | Open Source | Tools

Glimpse NuGet packages

I've blogged about Glimpse since the day I first saw it at Mix 2011's open source fest. It's popular, but frankly, Glimpse is so useful more people need to know about it.

From within your ASP.NET application in Visual Studio, install Glimpse using NuGet. You'll want to install the right Glimpse packages for the ASP.NET features you're using. For example, I'm using MVC4 and Entity Framework 5, so I will use NuGet and:

install-package Glimpse.MVC4
install-package Glimpse.EF5

These packages pull in the core Glimpse libraries plus the hooks for the specific ASP.NET modules and handlers needed for Glimpse to collect all the information about your application and present it to the client side. Be sure to pick the right NuGet packages for your project type.

The releases of Glimpse 1.4.0, and now most recently 1.5.0 improve Glimpse with the addition of a really amazing HUD (Heads Up Display). As you hover over each segment, it pops up with lots of details about the HTTP request, AJAX requests, deep inspection database interactions, and lots more.

Glimpse's new HUD

Here I've hovered over one segment and you can see the time it took to render this first page, and exactly how much time was spent during each activity, from rendering to action methods to database connections.

The Glimpse HUD expanded

You can move from the HUD to the standard Glimpse view. The best part is that each Glimpse Tab is a plugin itself! There's a whole community creating Glimpse Plugins. If you're using RavenDB, or NHibernate, or SignalR or whatever, you can get introspection into what's going on in a Glimpse Tab.

You turn Glimpse on and off with cookies, and you can setup security policy however you want. Glimpse isn't in the background creeping around - you have absolute control over when you want it used. Perhaps local and only when debugging, or perhaps always and with a specific cookie value, it's up to you.

Below you can see the actual SQL query executed by my Entity Framework code and how long it took to execute. I didn't have to change any part of my code or do anything more than just install Glimpse. Glimpse added the modules and handlers, and Glimpse policies can be installed to turn Glimpse on or off based on any option I can think of. I can even put Glimpse into production and only turn it on for certain requests, giving me a profiling tool I can peek at whenever I like.

EF SQL queries viewed within Glimpse

You likely use F12 developer tools in Chrome, IE and Firefox, and you've seen Timeline views before. But remember that Glimpse is JavaScript and HTML on the client - it's NOT a browser plugin - and it's a series of plugins on the server that give you a holistic view that's way more than just what's visible on the client.

Glimpse's Timeline View shows you exactly what's happening on the server, how long it's taking, and how it all fits together.


Sessions within Glimpse are all tracked and be optionally named. Since the server is collecting what's going on, you can pull out a popup browser window of Glimpse and connect to sessions from other browsers. Below I'm using an iPhone mobile emulator from ElectricPlum and inspecting requests from another browser window.

Using Glimpse to debug remotely against an iPhone Emulator

Glimpse is all open source and under the Apache 2.0 license. You can certainly help out, but the most interesting thing in my opinion is writing Glimpse Tabs - extending Glimpse to collect and show new data. Tabs can show technical stuff, but even business stuff that's specific to your application or style of application. For example, the Umbraco CMS could make a Glimpse Tab that puts configuration or technical Umbraco specific details up front. A line of business app could show tax details or shopping cart contents.

Glimpse is so useful that it's the first thing I install after I File | New Project on any non-trivial thing I'm working on. It's replaced Mini-Profiler as my go-to "production profiler" for web apps, and if you use ELMAH to collect and manage your application errors, there's even a Glimpse ELMAH plugin!

Check it out and go talk to Anthony and Nik about Glimpse on Twitter and thank for their work!

DISCLOSURE NOTE: The Red Gate company sponsors the Glimpse open source project. Red Gate also sponsored my blog feed this week. That is a cool coincidence, but it's just a coincidence. Red Gate does a lot of stuff. This post about Glimpse was written earlier. Just an FYI for y'all.
