/WINMD (Generate Windows Metadata)
Enables generation of a Windows Runtime Metadata (.winmd) file.
/WINMD[:{NO|ONLY}]
Arguments
/WINMD
The default setting for Universal Windows Platform apps. The linker generates both the binary executable file and the .winmd metadata file.
/WINMD:NO
The linker generates only the binary executable file, but not a .winmd file.
/WINMD:ONLY
The linker generates only the .winmd file, but not the binary executable file.
Remarks
The /WINMD linker option is used for UWP apps and Windows runtime components to control the creation of a Windows Runtime metadata (.winmd) file. A .winmd file is a kind of DLL that contains metadata for Windows runtime types and, in the case of runtime components, the implementations of those types. The metadata follows the ECMA-335 standard.
By default, the output file name has the form binaryname.winmd. To specify a different file name, use the /WINMDFILE option.
To set this linker option in the Visual Studio development environment
Open the project's Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.
Select the Configuration Properties > Linker > Windows Metadata property page.
In the Generate Windows Metadata drop-down list box, select the option you want.
