I create a console project with .net framework 4.7.2 then install akka.net from nuget.org but receive error on output window

Akka.NET should not have any problem with .NET 4.7.2, can you check your NuGet settings?

'Akka.Analyzers 0.2.4'.

@Arkatufus don't we have tests now to ensure that Akka.Analyzers works properly on all .NET and Roslyn versions that .NET Standard 2.0 supports? I recall we had to add those last quarter.

Can you provide correct nuget settings?

Any update to this issue? Having the same problem, Akka.Analyzers preventing Akka.NET to be installed on .NET Framework.

Ah sorry, but yes - we had another version of this same discussion pop up as a bona fide GitHub issue: #7307

TL;DR; this is an issue with the version of MSBuild you're using, not the version of .NET. If you upgrade to an MSBuild15-style project (which you can do without changing your .NET version) this issue should go away. The alternative is for us to downgrade Akka.Analysers to an older version of Roslyn.

xunit ran into this same issue and the .NET team is still discussing making some fixes to the runtime for older-style projects - you can follow those links on my comment here: #7307 (comment)
