#43028 is adding DOTNET_CLI_DO_NOT_USE_MSBUILD_SERVER to build YAML to workaround SDK update issue.
This is a temporary fix and should be removed when no longer needed.
Example,
# !temporary! Remove as soon as .NET SDK includes a new-enough `msbuild` to make this hack unnecessary
DOTNET_CLI_DO_NOT_USE_MSBUILD_SERVER: true
