/WINMDFILE (Specify winmd File)
Specifies the file name for the Windows Runtime Metadata (.winmd) output file that is generated by the /WINMD linker option.
/WINMDFILE:filename
Remarks
Use the value that is specified in filename to override the default .winmd file name (binaryname.winmd). Notice that you do not append ".winmd" to filename. If multiple values are listed on the /WINMDFILE command line, the last one takes precedence.
