NetCore2.1->2.2 Upgrade Issue; TargetFramework dropped/not recognized

From @pinkfloydx33 on December 5, 2018 13:40

I’m trying to upgrade my web application from netCore 2.1 to 2.2. I have updated the TargetFramework to netcoreapp2.2 and I receive the following errors upon restore/build/clean:

MyProduct.Web.csproj : error NU1202: Package Microsoft.AspNetCore.App 2.2.0 is not compatible with netcoreapp2.1 (.NETCoreApp,Version=v2.1). Package Microsoft.AspNetCore.App 2.2.0 supports: netcoreapp2.2 (.NETCoreApp,Version=v2.2)

I have also done a manual clean (deleting obj/bin directories).

I can build if I change from using <TargetFramework> to <TargetFrameworks>, however I’d rather not do this and attempt to locate the underlying issue. I have two test projects in the same solution that reference the main project. I was able to migrate them to netcoreapp2.2 without switching to TargetFrameworks, I would like to do the same thing for the main web app.

When I use TargetFramework (singular), Visual Studio updates the dependencies graph and removes the SDK node:

I’ve tried adding a global.json specifying the SDK version directly as 2.2.100 but that doesn’t make any difference.

Here is my .csproj file:

<Project Sdk="Microsoft.NET.Sdk.Web">

	<PropertyGroup>
		<AssemblyName>MyProduct.Web</AssemblyName>
		<OutputType>Exe</OutputType>

@sven5 If you have any saved publish profiles, make sure you’ve updated the framework version inside them as well.

Had to do the the above but also I additionally had to update deployment scripts as my output path had changed to reflect the new version. Best to do a search for all references of netcoreapp2.1
