[ NativeAOT ] error MSB4057: The target "PrepareForILLink" does not exist in the project

[FoggyFinder]

Unable to build a solution anymore.

I've found PR #547 where in one comment was mentioned that "I assume it will no longer work withe .NET Core 3.1 SDK."

So there is no way to use CoreRt/NativeAOT with .Net Core 3.1, right? If so

• shouldn't be the error message more clear ?
• shouldn't be the section Know issues (I suppose there is a typo Know**n**) updated / removed in such case ?

Otherwise the Q is how to fix it ?

[MichalStrehovsky]

Yes, I wanted to add a more clear error message but got stuck figuring out the MSBuild goo to say ".NET 5 or later". I updated prerequisites to say .NET 5 is needed but nobody reads all documentation. We should definitely delete the "how to use with .NET Core 2.1" since nobody tests that.

[MichalStrehovsky]

We might also be able to say in the ILCompiler NuGet package that .NET 5 is required so that this fails during restore.

This also has the problem that I don't know off the top of my head where to do that. The NuGet building infrastructure the ILCompiler package hooks into is... complex.

We should really only need .NET 5 SDK. I do not think there is a problem with targeting older TargetFramework that the nuget restore is based on.

The error message has been improved.
