Using .NET Core SDK 2.1.0-rc1 with TFS Build

So .NET Core 2.1 RC is out. With its Go Live Support I am fairly confident that I could upgrade my super secret project.

Upgrading my projects was easy.

I download and installed the 2.1.300-RC1 from https://www.microsoft.com/net/download/dotnet-core/sdk-2.1.300-rc1  and for VS2017 it should also show on your notifications window by the way.

Once my tools are upgraded I then did some minor changes on all of my CSPROJ.

Make sure that the target framework is 2.1 and the Package Reference version is 2.1.0-rc1-final. Rebuild and viola, .NET Core 2.1.  Here’s an example of one of my API’s.

I would not cover the other new and shiny things about .NET Core 2.1-RC like the one from Preview1 and Preview2 but certainly you can look it up here: https://blogs.msdn.microsoft.com/webdev/2018/04/12/asp-net-core-2-1-0-preview2-now-available/

Publishing to Azure

So now for the harder part. I saw from a blog post that Azure App Service will start deploying 2.1 RC next week.

But the the impatient me, went ahead used the .NET Core Tool Installer.

I used the name from the release notes https://github.com/dotnet/core/blob/master/release-notes/releases.csv

Broke my build saying that the .NET Core Package name is wrong.

But I saw this GitHub Issue thread that says use “To use 2.1.0-RC -> to download SDK, use “2.1.300-rc1-008673”. And to download runtime, use “2.1.0-rc1”.

Viola! That works!

Now for the fun part.

Using UseHttpsRedirection and HTTPClient Extensions!

That’s all for now!
