Handle Project Reloads when adding files to wildcard patterns

[TheAngryByrd]

We should add logic to handle Wildcarded files in fsproj files such as:

<Compile Include="CodeFixes/*.fsi" />
<Compile Include="CodeFixes/*.fs" />

In Adaptive, the additional dependencies is where it makes sense to watch for these files. We probably only want to do it upon Add or Delete but not modify.

Current workarounds:

• Option 1: Reload Window (not ideal)
• Option 2:
  • Save the fsproj file to mark it as updated
  • go to a file that it does know about (something that isn't wildcarded for example) and get it typechecked to force it to reload that project

Some initial investigation:

MsBuild expands out wildcarded Compile nodes on the parsing step. I could use an XPath to get these nodes but it won't for things that have variables like <Compile Include="$(RootPath)/Codefixes/*.fs" /> I'm not sure how to get MsBuild to return some partially applied path without expanding the wildcard and replacing variables without doing a lot of manual work.
