Mono WASM PInvoke Table generation does not handle file scoped types #93999
Description
Description
File scoped types are named like <File_Name_Without_Periods>Hash__ClassName. For UnmanagedCallersOnly methods in file-scoped types, Mono tries to generate a method in C, but it doesn't escape the name. As a result, you get errors like the following:
