将.net类库移植到Windows应用商店类库

Question

I have a class library that targets .net 4 and is used across different platforms via Mono. I now want to port it to be used by Windows 8. I know the name keeps changing but this is currently called a "Class Library (Windows Store Apps)" in VS2012.
I initially started with trying to port everything to a "Portable Class Library" but this was proving too difficult as some things simply didn't have a generic approach that would work on all platforms targeted, and other things that were supported simply weren't available to the compiler.
So I've created a Windows Store Class Library and created links to the existing files of my standard Class Library so updating once will update both. I am planning on using pre-processing directives to make changes between the two class libraries EG

#if NETFX_CORE
    Task.Delay(someTime);
#else
    new System.Threading.ManualResetEvent(false).WaitOne(sometime);
#endif

My question is if this method seems a sensible approach? I have the same default namespace and assembly name. Could this ever cause issues to my compiler? The assemblies target different platforms so would never be used together in the same application but do both sit in the same solution in Visual Studio.

Answer 1

Overall, yes that should work. That specific case is a poor example, because the two implementations function very differently, illustrating that you may need to rethink some aspects of your design. For cases where there is a similar API swap (with similar semantics), I personally tend to move the difference behind a helper method, so my "main" code doesn't need to worry about this - just the helper code. Reflection would be a good example of this (the changes to reflection are annoyingly deep).

The two projects with different target platforms should be fine. I occasionally hit an IDE glitch where it complains about temp files. I think this is due to sharing files between projects. I've logged it on connect

Task.Delay(msDelay).Wait()
