Answer 1

The Microsoft-hosted agent "windows-latest" hosts on the VM image that is Windows Server 2022 with Visual Studio 2022, and .NET 8 is the default .NET Core tool. The pre-installed .NET Core tools on this agent are listed here.

And here is the list of .NET tools supported in Visual Studio 2017.

They are different versions and might have compatibility issues. If you directly move you project from VS 2017 to VS 2022, the issue could occur.

What you can try is one of the ways below:

1. Set up a self-hosted agent on your local machine which has VS 2017 installed. Then use this self-hosted agent to run the build in pipeline.

2. Upgrade the VS to 2022 on your local machine. Then open the project in VS 2022 and try to upgrade it to be compatible with VS 2022.
