Converting an ASP.NET Core RC1 Project to RC2

datascreenWith the release of ASP.NET Core RC2, Microsoft hit a major milestone. But this change isn’t a trivial one. It’s a big change.

Since I’m updating my Pluralsight course on ASP.NET Core, I wanted to get a list of changes for the new version. I figured I’d share all the changes I could find converting a stock RC1 project to a RC2 one. It’s a big list, but hopefully manageable. Please share in comments and changes I missed so others can be helped!

First, change the framework to the new naming style. For dxcore use:

Getting Ready for ASP.NET Core RC2

I’m starting to play with the Preview of RC2 (nightly builds). It’s not time to do it for most people, but I’m trying to prepare for the update to my ASP.NET Core RC1 course on Pluralsight.

I have a couple of small library projects that I created when I build the new website. Since they are both pretty small and have xUnit testing, I thought it might be a good place to start.

I started by branching the projects so that I could merge them after RC2 shipped. The one I’ll walk you through is the MetaWeblog project. This is a small middleware for ASP.NET Core to support the Meta Weblog API to support Windows Live Writer (and other tools) for writing your blog items. You can see the comparison between the master and the RC2 branch here:

The Future of project.json in ASP.NET Core

aholebabyIf you’re not paying attention to Twitter, the ASP.NET Standup or the Github repositories, you might be missing a big change coming to ASP.NET Core. Now is time to add your opinion so that Microsoft can make the right move.

I suggest you read up on the change and make your voice heard if you have an opinion. My opinion is pretty clearly stated in the GitHub discussion so I won’t bother to repeat it here, but I’m asking you to get involved.

Microsoft has decided after the RTM of the ASP.NET Core framework to phase out project.json and use MSBuild for build data. They’ve not decided whether to keep the NuGet dependencies in a pared down project.json (maybe renamed to nuget.json) or whether to just allow for a command-line action like “nuget install dependency --save” to mirror what other package managers do.

Writing API Controllers in ASP.NET MVC 6

Audio and video plugs in handBefore ASP.NET Core, our world was split between ASP.NET MVC and ASP.NET Web API. In ASP.NET Core that changes to a single model in ASP.NET MVC 6 for handling requests, whether they end up returning data or views.

There is a Web API Shim to bring over old controllers for use in ASP.NET Core. But for new projects (e.g. greenfield), I’d suggest writing your API controllers without the shim.

In case you haven’t looked at View Controllers, Let’s look at a simple example from my WilderBlog project:

On the Road Again...

The Hello World Road Trip part two has started. Me and the missus headed out of Atlanta to Belgium for our first stop.

We arrived at Techorama, I did a couple of talks and recorded our Belgium podcast with the great Bill Wagner. That should be up this weekend.

We have just over half of the stops left in the trip. If you want a chance to see me record a live podcast and talk about ASP.NET Core, sign up for this free event in the following cities:

Deploying ASP.NET Core RC1 to Azure App Services

cloudraysAs you can see, I recently updated this blog. I wrote the new blog using ASP.NET Core RC1 (as related technologies) so when time came to deploy it, I had some issues.

At the time I thought it was Azure, but after testing with an empty project that worked, I figured it was probably something I did. In this post, I’ll talk about what I did to get it to work in Azure Websites.

There a couple of ways to do this. I preferred the publish from source approach. You can use the Visual Studio publish options too:

Implementing an ASP.NET Core RC1 Logging Provider

LumberI recently added a logging provider to my open source project (WilderBlog). I know I shouldn’t have implemented a provider myself, but I wanted to see how the sausage was made.

The reality is that I should have used an existing library like Serilog or others, but digging into the logging framework taught be how the system works. I’m hoping to show you what I learned.

Before we get started with what I did, let’s talk about how logging works. In Startup.cs you can ask for the ILoggerFactory object which you can use to support different types of logs. For instance, here is the DebugLogger being added when we’re running under development:

Using Cache in ASP.NET Core 1.0 RC1

When I created my blog in ASP.NET Core, I forgot about one feature that I used to help out some other Pluralsight authors by creating a quick top 100 list of courses. Because Pluralsight doesn’t really expose that data as an API, I didn’t want to hammer their service, so I had been using a memory cache to do it.

But when I moved the code over, I realized that the old, reliable Cache object was missing. Luckily I found it and like much of ASP.NET Core, adding it was simple and consistent. Let me show you.

First thing was to see how caching was being handled. Instead of having different caches, ASP.NET Core has an abstraction around caching and then you can support different types of caches. For me, it was a simple memory cache I wanted so I needed two Nuget packages:

Welcome to the New Wildermuth.com

javascriptA while back, I decided that this blog deserved a clean coat of paint and since I’m digging into ASP.NET Core, it was logical to re-write it. I wanted more than just to change the look, I wanted to make some real changes to the code and finally open source the code too!

Open sourcing the code required that I do a few things. First of all, I had to change any code that I would be embarrassed by (not a trivial task), but also make it so that much of normal secrets weren’t exposed by open sourcing it (e.g. connection strings, etc.). But as of now, I’ve done it. The source is available and the site is live! I am sure that there are issues with the site, but hopefully I’ll iron those out as they crop up.

My goal here wasn’t to build a blog engine. This isn’t a carefully designed and architected solution that is easily skinned for your site, but it should be a good start to understand how to build a site with ASP.NET Core and related technologies. You can see the code here:

Content Negotiation in ASP.NET Core

aspcore-1024x355As you might know, in ASP.NET Core, the MVC6 stack now includes the Web API functionality. Having a single stack has advantages and I’m happy they’ve converged the two stacks.

While working with early builds, I noticed the patterns for doing content negotiation weren’t working as expected so I defaulted to the MVC approach to REST APIs. In the RC1 build, it seems to be working as expected. Let’s talk about it.

ASP.NET Core gives you options. You could write APIs like I started to in earlier builds:
