I have a class library targetting both net481 and net8.0 I installed visual studio 2022 on the agent server in order to build the net 8.0 version of the project.

Now i get following error(s):

Any suggestions on what might be posing the problem? I already upgraded nuget codedom package to the latest version

• c#
• tfsbuild
• multitargeting
• tfs-2017

• did you try restoring NuGet: dotnet restore dotnet clean dotnet build – Emad Kerhily Commented 13 hours ago

Check the .csproj File: Make sure that the paths to the NuGet packages are correct and that they are included for both target frameworks. You might need to add conditional references if the paths differ between frameworks.

I ended up just deleting the lines where it wanted to import the analyzers in the csproj
