What a lovely time we had at DotNetFringe last week here in my hometown of Portland. Wonderful speakers, great topics, good friends, and an energized open source community. Videos will be coming soon, I'm told, for you to enjoy!

What is/was .NET Fringe?

.NET Fringe is a new conference focused on .NET developers who are breaking the rules and pushing the boundaries. The .NET platform is more interesting today than it ever has been! The old Microsoft that was at odds with Open Source has been replaced with one that is actively contributing to OSS and hosts a huge number of important projects on GitHub! The .NET OSS community has been collaborating and creating new, really exciting, interesting, and innovative projects which are changing the landscape. They are defining the future!

We had a great keynote from .NET OG Jimmy Bogard and lots of amazing talks. Here's just a sample:

And really, so very much more. This is just a taste of the fun, fast, and often 300-level .NET content that the community brought to .NET Fringe.

The DotNetFringe 3D Printing Labs!We also reached out to the Portland 3D Printing Lab and setup a number of inexpensive 3D Printers and had them running the whole time! I've been into 3D Printing of late and promoting the Maker Movement and we wanted to bring the joy of making to .NET Fringe as well! Many thanks to Ben and Bob for helping with this project!

Fringe was a great kick off to conference season for me.


Next up is BUILD in San Francisco. We've got some surprising announcements that are gonna blow your mind. You were impressed with what we've been doing with .NET and open source? We're just getting started. Big stuff coming soon.


If you couldn't get into BUILD or missed .NET Fringe, join me down in Arizona in May for AngleBrackets and DevIntersections.

This time I'm also joined with my friend from CodeNewbie and Ruby Rogue, Saron Yitbarek to talk about all the great stuff we can do as developers on the open web.

AngleBrackets will have sessions on node.js, ASP.NET 5, CSS, JavaScript, the Ionic Framwework, Google Analytics, AngularJS, IOT, Roslyn, and so much more.

Register now for AngleBrackets and be sure to check out the Package deals that include Pre-Conference Workshops AND a Surface 3 or Xbox! Here's a nice video promo showing the fun we have at AB.

I'm looking forward to meeting you, Dear Reader, at a conference one day, perhaps this year, perhaps next! Be well.

Introducing Azure Resource Explorer for the Azure Resource Management APIs

April 9, '15 Comments [8] Posted in Azure | Web Services
Sponsored By

When managing Azure resources (Virtual Machines, Web Apps, etc) I like to do most of my work in Azure from the command line using the "Azure xplat cli" - the Azure Cross Platform Command Line Interface. It's an Open Source node.js app that you can get with "npm install -g azure-cli" and it calls the backend REST services that all of Azure uses to manage itself. In fact, when you are using the Azure Portal it's calling the same backend.

It's mostly an "Azure Noun Verb" structure, as you can see in the figure below. You can Azure Site Create or Azure VM Restart, etc.

Azure Command Line Syntax

You can ALSO add --json to the xplat cli to see a JSON representation of the result of your call. So Azure Site List --json gives you a lot more information than without the json switch.

There's a PowerShell interface to Azure, this xplat nodejs one I'm using, as well as other libraries like the Azure Management Libraries for .NET again, all calling the backend REST API.

However, that REST API is huge and confusing. Enter David Ebbo, a Principal Development Lead on the Azure App Platform. He's made the Azure Resource Explorer at as a great way to explore the Azure Resource Management APIs visually and interactively!

And, wait for it, Azure Resource Explorer is, of course, Open Source and hosted here at GitHub It's a preview/beta and not done, but we're all interested in what YOU think! Does it do what you'd expect? Feel free to add issues and get involved in the repository.

Go hit and login with your Azure Credentials. It's an Object Explorer if you've ever used Visual Studio to move around a large object model, except this is a resource try of all the hypermedia nodes within your view of Azure.

Azure Resource Explorer

Here I am moving around my Web Applications that I host in the West US Region of Azure. I can see the deployment slots for staging and production, the source control system and web hooks that deploy my site and lots more. Notice that I can click Actions as well, and (when I turn Read-Only off) perform POST and DELETE calls that will affect my Azure resources.

If you're familiar with Postman, the REST API development tool, this is kind of like Postman for Azure. Here's a 5 min YouTube video by David Ebbo walking you through the Azure Resource Explorer.

To be clear, this is NOT a new Portal, and it IS very low level. This is a tool for folks who want to know what's really going on when an Azure API is called. Perhaps you're creating your own explorer or your own API client in another language. This tool can give you documentation and live examples on how to call those APIs correctly.

Again, it's Open Source and hosted here at GitHub. They would be thrilled to hear your thoughts. Is this useful? In what direction would you like it to go?

By the way, if you'd like to try Azure for an hour for free without signing up for any trials or anything, go check out and play! Also, check out Azure Friday at and subscribe on iTunes.

On the importance of OpenSearch

April 3, '15 Comments [29] Posted in Open Source
Sponsored By

I'm a big fan of Open Search, the idea, the format, and the user experience it can enable. You start typing a domain you've hit before that you want to search within. When it starts autocompleting, you hit tab, and then type your search.

So, "stacko - TAB - json - ENTER" has me searching StackOverflow for json results. I don't have to google/bing and then add "" to my query. I don't have to hit the home page then look around for a search box. The site just includes a meta tag and an opensearch.xml file and poof, the site has taught my browser how to search. Once you've tried this, you'll find it hard to browse/search without. You'll prefer sites that include it and be frustrated with sites that don't. (More on that later.)

IMPORTANT UPDATE/NOTE: A buddy of mine points this out, and he's right. That said, I want to say that I like BOTH of them, and I'm very much enamored with the Tab Search feature.

"Just to be clear, these things are not the same thing.

  • OpenSearch is a format for specifying how to search a site. 
  • Tab Search is a particular UX for allowing you to do a search on a non-default search provider. It happens to use OpenSearch to learn how to search different search providers."
  • I setup OpenSearch at back in 2009!

    Chrome has a great implementation of Open Search.

    Type, Tab, Type, Enter

    I just added a one line META tag and a static XML file. Boom.

    Your static XML file describes what the resulting URL should look like. Here's a small example.

    Hanselman Search
    Search Scott Hanselman's Blog

    This is such a clean and obvious user story. It makes your web browsing experience better.

    User wants to easily search within a site they visit often. Every browser and OS should support OpenSearch.

    Amazon used to support it but in the last year or so removed it in a homepage redesign. It's more than a little ironic that it was and that came up with OpenSearch and actually host the websites, but now the home page doesn't support it.

    If you work for Amazon and are reading this blog post, consider this your calling out. Please put OpenSearch back on

    Dear Reader, take a minute and see if your favorite browser supports OpenSearch. If it does, try it out. If not, ask them for it. Same for your favorite sites. If you run a site, you can easily add OpenSearch in a few minutes.

    Setting up a VPN and Remote Desktop back into your home with a Synology (from an iPhone)

    April 2, '15 Comments [27] Posted in Hardware | Open Source | Win8
    Sponsored By

    It's amazing that I can basically be my own IT Department. The kinds of things we can do in our homes as individuals with off-the-shelf hardware would have needed an IT Dept of a dozen just 10 years ago, ya know? Amazing.

    I wanted to be able to VPN into my home and remotely access my machines and files. I do very much realize there are a lot of different options to do this, and have been for years. From GoToMyPc to Hamachi, again, there's dozens of ways. I wanted a VPN solution I could use on my iPhone/iPad and Surface. I wanted it to be standards-based and not require any additional software installations.

    I have a a Synology 1511+ NAS appliance and I love it. It's not just a file server, it's an everything server, in my house. I use it for Plex, it hosts my files and photos, it manages my surveillance cameras and acts as a camera DVR, it runs a Minecraft Server, it's a Git server, it even runs Docker.

    The Synology will act as my VPN server as well.

    Here's how I set up four things. The Synology, my Router, my iOS device, and my Windows PC/Surface.

    The result is I can now remote into my home and manage things from any device I own.

    Setting up a Synology for L2TP VPN

    First, in the Synology Package Manager, ensure that you've got the Synology VPN Server package installed and running.

    Adding VPN Server on Synology

    You should give some though as to which VPN technique you want to use. I decided on L2TP, although there is some concern the NSA has weakened it. Benefits are that it's on all major platform, it's generally considered secure, and it's easy to setup.

    Select L2TP (or whatever you want), and Enable it. Notice also that I selected my INTERNAL DNS server. I found this worked best for me when trying to access internal resources. You can also setup a hosts file if you want to just hit a few things inside your house.

    L2TP in Synology

    Now click on Privilege. Just give the minimum privileges to the user that needs them. NO need to give VPN access to users who won't use it.

    VPN Server in Synology

    Setup your Router for VPN (L2TP)

    My router is a Linksys WRT1900ac that I like very much. It supports port forwarding, and the Synology can often talk directly to a router and request open ports. However, there's something to be said for handling things yourself. It lets you know exactly what's going on, and it can be less of a "black box."

    Login to your router and in this case of L2TP, forward UDP ports 1701, 500, and 4500. On my Linksys, it's under Security, Apps and Gaming.

    The Device IP is the internal IP address of your Synology. It's best to have your Synology use a Static IP address, or at least have a DHCP reservation so this IP doesn't change and things stop lining up.

    Port Forwarding in a Router

    Also, ensure that your Router is passing L2TP traffic as well. I changed this under Security.

    L2TP Passthrough

    At this point, you should be able to at least try to connect to your house via VPN. I did this as a quick test by taking my iPhone off the wireless networking (thereby being on the open internet) and VPN'ing back in.

    If you succeed, you should be able to see yourself in the VPN Server | Connection List area on our Synology.

    VPN Server

    Here's what I did on my iDevice to setup VPN.

    Setting up iOS/iPhone/IPad for VPN

    From the iOS Settings app, go General | VPN. Touch Add VPN Configuration. I selected L2TP and put in my Server name or IP and named the account "home."

    NOTE: If you don't want to use your IP address, you can use the dynamic DNS feature built into your Synology, or any one of many dynamic DNS systems that will give you a nice domain like "" or whatever. You can also, if you like, setup a CNAME with your own domain and point it to that dynamic domain. So could be your server, if you wanted.

    With L2TP you'll need your username and password, as well as a Shared Secret. That's like another password. Specifically the Secret text box in iOS is the "pre-shared key" from your Synology L2TP VPN setup.

    Add VPN in iOS

    At this point you'll get a nice VPN option on your Settings app under Personal Hotspot that wasn't there before. You can turn it on and off now, easily.

    VPN Connecting in Settings

    Once I'm VPN'ed in I can see a [VPN] indicator in the top status bar. I've installed the FREE Microsoft Remote Desktop Client for iOS.

    RD Client on an iPhone - Remote Desktop

    And here's me VPN'ed into my home PC from my iPhone. This of course, can be done on Android and Windows Phone as well.

    Remoted into my desktop at home with RDP

    It looks small, but in reality it's very usable, especially from an iPad with a Bluetooth Keyboard.

    Setting up L2TP VPN on Windows 8.1

    Now I'll setup VPN back to home on my Windows 8.1 machine. For some reason this was super easy in Windows 7, but in Windows 8.1 there isn't a clear way to just add a L2TP VPN. You can add other simpler (or Vendor) VPNs in a straightforward manner, but not L2TP.

    Just hit the Windows key (or Start Menu) and type "Add VPN." When you get to the VPN management screen, you'll see this and can fill it out.

    Adding VPN

    But L2TP VPN setup with a pre-shared key requires some more work. If you know of a simpler way, let me know. I can see about three different ways to get to the same result.

    Go ahead and create a new VPN connection with the menu above. Select Microsoft as the VPN type and put in your server address and optionally name and password. This will create the VPN connection.

    Pay attention now. Go back to the Start Menu and type "Network Connection." You want the first item called "View Network Connection" (a classic control panel, not a fullscreen 'metro' one).

    Opening Network Connections

    From there, you'll open a classic control panel and see your VPN connection. Right click and click Properties.

    Network Connections with VPN

    Click Security, make sure L2TP is set, then click Advanced Settings.

    L2TP VPN in Windows 8'

    Put your pre-shared key there.

    Setting a preshared key

    Connect to your home VPN and have fun

    Of course, please do remember to use strong passwords, strong pre-shared keys, and change them. Don't be lazy.

    At this point you can connect to your home/office and work to your heart's content.

    VPN Connection in Windows 8

    For some of you this is "duh" or old hat, but for me it was something I just never got around to doing. Mostly laziness prevented. But just last week I had to drive 30 miles back to my house from a dinner in order to move a file from my Desktop into Dropbox. I'm pretty sure I'm not the only reasonably smart techie with a story like that. This VPN setup would have meant I could do that from my phone and it would have saved me a big hassle and over an hour of my time.

    Hanselman's Desk of Hardware

    I'd like to take a moment and be proud of myself and my friend Saron. This last month, March of 2015, we teamed up at decided to come up with a scheme to get folks excited about Making. By making, I mean creating physical things with hardware like Arduino, Raspberry Pi, soldering things, and generally using electricity and software to do awesome stuff.

    A lot of us are software engineers, but we don't realize how powerful we can feel when we do things with the software and hardware.

    Getting that LED to flash is just the beginning. When you can affect your physical world, the sense of empowerment is intoxicating. This is fantastic not only for old-timers like myself, but also young people and kids who may be looking into engineering as a career.

    All month long we did podcasts, blog posts, Twitter chats, and live Google hangouts, all with the goal to get you, dear reader, excited about hardware. I'm REALLY proud of what we accomplished. Note that we both do this on the side as volunteers while holding down regular jobs.

    Please Subscribe Now

    I don't think I ask you for much, but I will ask you right now to take a moment and subscribe to our two podcasts using your favorite podcast application:

    • CodeNewbie is the most supportive community of programmers and people learning to code. Tune in every week for stories about people on their coding journey.
