and yet

$ dotnet --list-sdks
5.0.408 [/usr/share/dotnet/sdk]
6.0.108 [/usr/share/dotnet/sdk]

$ dotnet --list-sdks
5.0.408 [/usr/share/dotnet/sdk]
6.0.108 [/usr/share/dotnet/sdk]

What might I be missing to tell msbuild where to find these?

Dear lord why

sparrOP•3y ago

this is a library, not mine, that targets as wide of coverage as possible I don't actually need to compile against all of those; I'd be happy to test with just one

How are you building this project?

sparrOP•3y ago

msbuild

333fred•3y ago

You can't use msbuild with .NET Core/5/6 If you need to use an msbuild command, use dotnet msbuild That will make sure you get the right things
