Turns out that HostFactoryResolverTests.cs was not being compiled, so there were no tests. This shouldn't be iOS/tvOS specific, but for all platforms.

This makes me wonder how many other test suites are missing tests as a result of not explicitly including the test files.

Note: this "library" is special, in that we don't build the library and ship it in a NuGet package. Instead, the source files are shipped in the NuGet package.

This looks like a mistake in the test .csproj. In Extensions libraries, we typically use <EnableDefaultItems>true</EnableDefaultItems>. But we didn't in these tests. I'll put a PR to fix it.
