Views in class libraries removed from embedded resources under certain circumstances

[svallis]

I have a test repo which should hopefully demonstrate this problem, and I hope this is the correct repo for the issue.

If you clone and open this solution and perform the following, the issue should be clear. First, the expected results is what happens when adding views to app:

• Go to app1\Views\Home and press SHIFT+F2 and create Test.cshtml
• Copy and paste the new file to end up with Test - Copy.cshtml
• Build the solution
• The .csproj file for app1 remains unchanged

Now perform the same process on lib1:

• Go to lib1\Views\Shared and press SHIFT+F2 and create Test.cshtml
• Copy and paste the new file to end up with Test - Copy.cshtml
• Build the solution
• The .csproj file for lib1 has the following added to it

<ItemGroup>
    <EmbeddedResource Remove="Views\Shared\Test - Copy.cshtml" />
</ItemGroup>

As you can imagine this is highly frustrating during development, and we're constantly running into it while developing features within a library. I don't know if it's an outright bug, or whether we could improve the existing rules in the .csproj for the library. Whatever changes are made to the library project file need to preserve existing functionality though, so that views are not included in the publish output and are embedded in the assembly. This allows everything to work both during development and after publishing with precompiled views.
