warning CS8021: No value for RuntimeMetadataVersion found. #1274

Closed freakmaxi closed 3 years ago

freakmaxi commented 3 years ago

Hello,

I have a little problem with .net 5.0. I have a web framework, that parses the c# code and compile it. When it is compiling it is adding the references to the CSharpCompilation using MetadataReference.CreateFromFile(assembly.Location)

It is working normally, however, if the web framework executable compiled to a single file and tries to compile the c# code coming from web framework code using MetadataReference.CreateFromFile(assembly.Location) assembly.Location is returning an empty string and it leads to failure. If I skip the empty values of assembly.Location for references, this time it is creating a huge error mention in the title of this issue. the whole output is like,

System.Exception: warning CS8021: No value for RuntimeMetadataVersion found. No assembly containing System.Object was found nor was a value for RuntimeMetadataVersion specified through options.

It was working with dotnet core 3.1 without any problem on both single executable or not. This problem has appeared with .net 5.0

Thanks
