Three FREE Training Courses on ASP.NET Core from Microsoft Virtual Academy

This time last year we did a Microsoft Virtual Academy class on what was then called "ASP.NET 5." It made sense to call it 5 since 5 > 4.6, right? But since then ASP.NET 5 has become .NET Core 1.0 and ASP.NET Core 1.0. It's 1.0 because it's smaller, newer, and different. As the .NET "full" framework marches on, on Windows, .NET Core is cross-platform and for the cloud.

Command line concepts like dnx, dnu, and dnvm have been unified into a single "dotnet" driver. You can download .NET Core at http://dot.net and along with http://code.visualstudio.com you can get a web site up and running in 10 minutes on Windows, Mac, or many flavors of Linux.

So, we've decided to update and refresh our Microsoft Virtual Academy. In fact, we've done three days of training. Introduction, Intermediate, and Cross-Platform and all three days are now available! We just released training for ASP.NET Core 1.0 Cross-Platform that shows Mac, Ubuntu, and Docker!

Head over to Microsoft Virtual Academy and watch our new, free "Introduction to ASP.NET Core 1.0." It's a great relaxed pace if you've been out of the game for a bit, or you're a seasoned .NET "Full" developer who has avoided learning .NET Core thus far. If you don't know the C# language yet, check out our online C# tutorial first, then watch the video.

Introduction to ASP.NET Core 1.0

Join experts Scott Hanselman and Maria Naggaga, and find out how to build .NET Core applications on any operating system. Bring your web development expertise and roll up your sleeves, for this first in a three-part series.

At the end of October I announced that Maria from my team and I published a Microsoft Virtual Academy on ASP.NET Core. This Free ASP.NET Core 1.0 Training is up on Microsoft Virtual Academy now for you to watch and enjoy! I hope you like it, we worked very hard to bring it to you.

Again, start with Introduction to ASP.NET Core 1.0, and explore this new technology even further in Intermediate ASP.NET Core 1.0.

Intermediate ASP.NET Core 1.0

Intermediate ASP.NET Core 1.0

We've just launched Day 2, the Intermediate day. If the first is 100 level, this is 200 level. In this day, Jeff Fritz and I build on what we learned with Maria in Day 1. We're also joined by Rowan Miller and Maria later in the day as we explore topics like:

  • Tag Helpers
  • Authentication
  • Custom Middleware
  • Dependency Injection
  • Web APIs
  • Single Page Apps
  • Entity Framework Core and Database Access
  • Publishing and Deployment

In a few weeks (maybe sooner) we'll publish Day 3 which we'll do exclusively on Macs and Linux machines. We'll talk about Cross-Platform concerns and Containers.

NOTE: There's a LOT of quality free courseware for learning .NET Core and ASP.NET Core. We've put the best at http://asp.net/free-courses and I encourage you to check them out!

Also, please help me out by adding a few stars there under Ratings. We're new. ;)

Exploring Wyam - a .NET Static Site Content Generator

December 11, '16 Comments [28] Posted in ASP.NET | Open Source
Sponsored By

It's a bit of a renaissance out there when it comes to Static Site Generators. There's Jekyll and GitBook, Hugo and Hexo. Middleman and Pelican, Brunch and Octopress. There's dozens, if not hundreds of static site content generators, and "long tail is long."

Wyam is a great .NET based open source static site generator

Static Generators a nice for sites that DO get updated with dynamic content, but just not updated every few minutes. That means a Static Site Generator can be great for documentation, blogs, your brochure-ware home page, product catalogs, resumes, and lots more. Why install WordPress when you don't need to hit a database or generate HTML on every page view? Why not generate your site only when it changes?

I recently heard about a .NET Core-based open source generator called Wyam and wanted to check it out.

Wyam is a simple to use, highly modular, and extremely configurable static content generator that can be used to generate web sites, produce documentation, create ebooks, and much more.

Wyam is a module system with a pipeline that you can configure and chain processes together however you like. You can generate HTML from Markdown, from Razor, even XSLT2 - anything you like, really. Wyam also integrates nicely into your continuous build systems like Cake and others, so you can also get the Nuget Tools package for Wyam.

There's a few ways to get Wyam but I downloaded the setup.exe from GitHub Releases. You can also just get a ZIP and download it to any folder. When I ran the setup.exe it flashed (I didn't see a dialog, but it's beta so I'll chalk it up to that) and it installed to C:\Users\scott\AppData\Local\Wyam with what looked like the Squirrel installer from GitHub and Paul Betts.

Wyam has a number of nice features that .NET Folks will find useful.

Let's see what I can do with http://wyam.io in just a few minutes!

Scaffolding a Blog

Wyam has a similar command line syntax as dotnet.exe and it uses "recipes" so I can say --recipe Blog and I'll get:

C:\Users\scott\Desktop\wyamtest>wyam new --recipe Blog
Wyam version 0.14.1-beta

,@@@@@ /@\ @@@@@
@@@@@@ @@@@@| $@@@@@h
$@@@@@ ,@@@@@@@ g@@@@@P
]@@@@@M g@@@@@@@ g@@@@@P
$@@@@@ @@@@@@@@@ g@@@@@P
j@@@@@ g@@@@@@@@@p ,@@@@@@@
$@@@@@g@@@@@@@@B@@@@@@@@@@@P
`$@@@@@@@@@@@` ]@@@@@@@@@`
$@@@@@@@P` ?$@@@@@P
`^`` *P*`
**NEW**
Scaffold directory C:/Users/scott/Desktop/wyamtest/input does not exist and will be created
Installing NuGet packages
NuGet packages installed in 101813 ms
Recursively loading assemblies
Assemblies loaded in 2349 ms
Cataloging classes
Classes cataloged in 277 ms

One could imagine recipes for product catalogs, little league sites, etc. You can make your own custom recipes as well.

I'll make a config.wyam file with this inside:

Settings.Host = "test.hanselman.com";
GlobalMetadata["Title"] = "Scott Hanselman";
GlobalMetadata["Description"] = "The personal wyam-made blog of Scott Hanselman";
GlobalMetadata["Intro"] = "Hi, welcome to my blog!";

Then I'll run wyam with:

C:\Users\scott\Desktop\wyamtest>wyam -r Blog
Wyam version 0.14.1-beta
**BUILD**
Loading configuration from file:///C:/Users/scott/Desktop/wyamtest/config.wyam
Installing NuGet packages

Executing pipeline "Posts" (4/7) with 6 child module(s)
Executed pipeline "Posts" (4/7) in 620 ms resulting in 1 output document(s)
Executing pipeline "Feed" (5/7) with 3 child module(s)
Executed pipeline "Feed" (5/7) in 134 ms resulting in 2 output document(s)
Executing pipeline "RenderPages" (6/7) with 3 child module(s)
Executed pipeline "RenderPages" (6/7) in 333 ms resulting in 4 output document(s)
Executing pipeline "Resources" (7/7) with 1 child module(s)
Executed pipeline "Resources" (7/7) in 19 ms resulting in 14 output document(s)
Executed 7/7 pipelines in 2936 ms

I can also run it with -t for different themes, like "wyam -r Blog -t Phantom":

Wyam supports themes

As with most Static Site Generators I can start with a markdown file like "first-post.md" and included name value pairs of metadata at the top:

Title: First Post
Published: 2016-01-01
Tags: Introduction
---
This is my first post!

If I'm working on my site a lot, I could run Wyam with the -w (WATCH) switch and then edit my posts in Visual Studio Code and Wyam will WATCH the input folder and automatically run over and over, regenerating the site each time I change the inputs! A nice little touch, indeed.

There's a lot of cool examples at https://github.com/Wyamio/Wyam/tree/develop/examples that show you how to generate RSS, do pagination, use Razor but still generate statically, as well as mixing Razor for layouts and Markdown for posts.

The AdventureTime sample is fairly sophisticated (be sure to read the comments in the config.wyam for gotcha) example that includes a custom Pipeline, use of Yaml for front matter, and mixes markdown and Razor.

There's also a ton of modules you can use to extend the build however you like. For example, you could have source images be large and then auto-generate thumbnails like this:

Pipelines.Add("Images",
ReadFiles("*").Where(x => x.Contains("images\\") && new[] { ".jpg", ".jpeg", ".gif", ".png"}.Contains(Path.GetExtension(x))),
Image()
.SetJpegQuality(100).Resize(400,209).SetSuffix("-thumb"),
WriteFiles("*")
);

There's a TON of options. You could even use Excel as the source data for your site, generate CSVs from the Excel OOXML and then generate your site from those CSVs. Sounds crazy, but if you run a small business or non-profit you could quickly make a nice workflow for someone to take control of their own site!

GOTCHA: When generating a site locally your initial reaction may be to open the /output folder and open the index.html in your local browser. You MAY be disappointed with you use a static site generator. Often they generate absolute paths for CSS and Javascript so you'll see a lousy version of your website locally. Either change your templates to generate relative paths OR use a staging site and look at your sites live online. Even better, use the Wyam "preview web server" and run Wyam with a "-p" argument and then visit http://localhost:5080 to see your actual site as it will show up online.

Wyam looks like a really interesting start to a great open source project. It's got a lot of code, good docs, and it's easy to get started. It also has a bunch of advanced features that would enable me to easily embed static site generation in a dynamic app. From the comments, it seems that Dave Glick is doing most of the work himself. I'm sure he'd appreciate you reaching out and helping with some issues.

As always, don't just send a PR without talking and working with the maintainers of your favorite open source projects. Also, ask if they have issues that are friendly to http://www.firsttimersonly.com.

Publishing ASP.NET Core 1.1 applications to Azure using git deploy

November 23, '16 Comments [19] Posted in ASP.NET | Azure
Sponsored By

I took an ASP.NET Core 1.0 application and updated its package references to ASP.NET 1.1 today. I also updated to my SDK to the Current (not the LTS - Long Term Support version). Everything worked great building and running locally, but then I made a new Web App in Azure and did a quick git deploy.

Deploying ASP.NET Core 1.1 to Azure

Basically:

c:\aspnetcore11app> azure site create "aspnetcore11test" --location "West US" --git
c:\aspnetcore11app> git add .
c:\aspnetcore11app> git commit -m "initial"
c:\aspnetcore11app> git push azure master

Then I watched the logs go by. You can watch them at the command line or from within the Azure Portal under "Log Stream."

The deployment failed when Azure was building the app and got this error:

Build started 11/25/2016 6:51:54 AM.
2016-11-25T06:51:55         1>Project "D:\home\site\repository\aspnet1.1.xproj" on node 1 (Publish target(s)).
2016-11-25T06:51:55         1>D:\home\site\repository\aspnet1.1.xproj(7,3): error MSB4019: The imported project "D:\Program Files (x86)\dotnet\sdk\1.0.0-preview3-004056\Extensions\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
2016-11-25T06:51:55         1>Done Building Project "D:\home\site\repository\aspnet1.1.xproj" (Publish target(s)) -- FAILED.
2016-11-25T06:51:55    

See where it says "1.0.0-preview3-004056" in there? Looks like Azure Web Apps has some build that isn't the one that I have. Theirs has the new csproj/msbuild stuff and I'm staying a few steps back waiting for things to bake.

Remember that unless you specify the SDK version, .NET Core will use whatever is the latest one on the box.

Well, what do I have locally?

C:\aspnetcore11app>dotnet --version
1.0.0-preview2-1-003177

OK, then that's what I need to use so I'll make a global.json at the root of my project, then move my code into a folder under "src" for example.

{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-preview2-1-003177"
}
}

Here I'm "pinning" the same SDK version. This will tell Azure (or you, if I gave you the code) to use this SDK version when building.

Now I'll redeploy with a git add, commit, and push. It works.

I think this should be easier, but I'm not sure how it should be easier. Does this mean that everyone should have a global.json with a preferred version? If you have no preferred version should Azure give a smarter error if it has an incompatible newer one?

The learning here for me is that not having a global.json basically says "*.*" to any cloud build servers and you'll get whatever latest SDK they have. It could stop working any day.
