We have updated out minimum .NET SDK version to 8.0.100 Preview 4.

If you use the build.cmd script's -vs flag, then there is no action required.

If you directly open the solution files in the repo in Visual Studio or you use environments that use the global SDK (such as Visual Studio Code), download and install the 8.0.100-preview.4 SDK globally from https://dotnet.microsoft.com/en-us/download/dotnet/8.0
