Linker Tools Warning LNK4224
An invalid, obsolete linker option was specified and ignored.
For example, LNK4224 can occur if a /comment directive appears in .obj. The /comment directive would have been added via the comment (C/C++) pragma, using the deprecated exestr option. Use dumpbin /ALL to view the linker directives in an .obj file.
If possible, modify the source for the .obj and remove the pragma. If you do ignore this warning, it is possible that an .executable compiled with /clr:pure will not run as expected.
