+    Workaround an MSBuild bug where Microsoft.Common.Test.targets is missing from the Arm64 installation.
+    See: https://github.com/dotnet/msbuild/pull/9984
+    NB 1: This means that using "/t:Test" is not supported for Arm64 builds and tests will need to be run in an alternate way,
+          eg running tests in VS or invoking vstest.console directly.
+    NB 2: <Sdk> elements do not support conditions, so this is also being worked around.
