TIL that the
<None Include="Foo.def" />line in our projects isactually totally meaningless. The important line is the one that's in
cppwinrt.build.pre.props, where we declareSo if you change a project's name, and not the
.deffile, then thelinker will just not use the
.deffile at all.More importantly, this seemingly doesn't matter in debug builds. In a
Debug build, the linker will happily still include
WINRT_CanUnloadNowand
WINRT_GetActivationFactoryin the exports from the dll, evenwithout the
.def. But in a Release build, the linker is much moreagressive about pruning symbols that aren't referenced, and without
those two, NONE of the symbols are eventually referenced.
This PR fixes
Microsoft.Terminal.Controlby renaming the.def, andmakes it marginally harder for someone to make the same mistake in the
future.
