While building

We can find the MSBuild.exe installed with Visual Studio 2022 Community from C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\MSBuild.exe.

We have not used AppVeyor. Maybe you can try specifying the path for MSBuild(17) in command line(not sure whether AppVeyor uses command line to build?) to compile it or just select VS2022 and .NET6.0 when you choose build settings.

The problem was that appveyor.yml in the repo had Visual Studio 2019 in it as the worker image. The way AppVeyor works, the yml file takes precedence over UI settings.
