There are several steps that should be taken to upgrade from ASP.NET Core 2.0 application to 2.1.

  1. Change in the .csproj project file <TargetFramework>netcoreapp2.0</TargetFramework> to <TargetFramework>netcoreapp2.1</TargetFramework>.
  2. Replace the version specified Microsoft.AspNetCore.All package reference with the versionless Microsoft.AspNetCore.App package reference. You may need to add extra dependencies as several packages from All aren't included in the App package.
  3. Remove all references to <DotNetCliToolReference> elements
  4. In your Startup.cs change services.AddMvc(); to services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); (otherwise it defaults to 2.0)

You'll need the SDK installed (available here). You'll also need to be running at least VS2017 15.7, but considering 2.1 is still a release candidate, I'd stick with VS2017 Preview for the time being (available here).

Once you have all that, you simply need to edit your csproj file(s) and change the target framework to netcoreapp2.1.

<TargetFramework>netcoreapp2.1</TargetFramework>

The latest Microsoft.AspNetCore.All NuGet package should then download automatically during the rebuild.
