C# compiler warning

A C# compiler warning is mapped to the host diagnostic format with its Roslyn CS identifier in the message. A warning alone does not reject a module. The compile server's normal report filter currently omits ordinary non-Ara warnings.

#Common causes

• Roslyn reports a non-error issue and that diagnostic is passed through the compiler diagnostic mapper.

#Fixes

• Read the retained CS identifier and correct the reported source issue at its location.

• Check accompanying errors before assuming the module was installed; this warning alone does not establish reload success.
