Repro steps
- Create new F# Console App (.NET Core) Project in Visual Studio
- Using the solution explorer, add a new folder in the project called "data"
- Then add a new file to that folder called "data.txt"
- Unload and modify the .fsproj file so that the following line:
<Content Include="data\data.txt" />
is replaced with:
<Content Include="data\*.txt" />
- Reload the project and try add a new file to the data directory
Alternative repro steps
- Clone my repo
- Open the .sln in Visual Studio
- Try add a new file to the input_files/2017 directory.
Expected behavior
The new file gets added to the project, but does not cause any modifications to the .fsproj file as it is already covered by the Content Include
Actual behavior
A recoverable exception is thrown causing the data folder to disappear from the project including the removal of the Content Include from the fsproj file. The stacktrace of the exception is as follows:

Known workarounds
I am able to resolve this by unloading the .fsproj file, readding the removed line, and loading again. Doing this shows the data folder with the original file and the file I attempted to create

Note: I attempted to recreate this issue on a C# solution but wasn't able to since C# projects do not require a Content Include to be added to the .csproj file for the directory to be included in the project.
