MonoDevelop overwrites project GUID to be lowercase instead of uppercase

[NatElkins]

Steps to repro:

1. Check out https://github.com/microsoft/visualfsharp
2. Open FSharp.sln using MonoDevelop.
3. Rename any project.
4. In repo, do git status
5. Observe that there are a bunch of updates similar to the following:

-Project("{F2A71F9B-5D33-465A-A702-920D77279786}") = "FSharp.Tests.FSharpSuite", "tests\fsharp\FSharp.Tests.FSharpSuite.fsproj", "{C163E892-5BF7-4B59-AA99-B0E8079C67C4}"
+Project("{f2a71f9b-5d33-465a-a702-920d77279786}") = "FSharp.Tests.FSharpSuite", "tests\fsharp\FSharp.Tests.FSharpSuite.fsproj", "{C163E892-5BF7-4B59-AA99-B0E8079C67C4}"

Note that F2A71F9B-5D33-465A-A702-920D77279786 gets changed to f2a71f9b-5d33-465a-a702-920d77279786.

I believe that MonoDevelop should not change the casing of these GUIDs.

what version of MonoDevelop are you using?

[NatElkins]

7.5 (build 1255)

I see it replaces other project GUIDs as well, for example:

-Project("{9A19103F-16F7-4668-BE54-9A1E7A4F7556}") = "ProjectSystem.Base", "vsintegration\src\FSharp.ProjectSystem.Base\Project\ProjectSystem.Base.csproj", "{B700E38B-F8C0-4E49-B5EC-DB7B7AC0C4E7}"
+Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "ProjectSystem.Base", "vsintegration\src\FSharp.ProjectSystem.Base\Project\ProjectSystem.Base.csproj", "{B700E38B-F8C0-4E49-B5EC-DB7B7AC0C4E7}"

The problem with the .NET Core project type guid 9A19103F-16F7-4668-BE54-9A1E7A4F7556 being changed back to the C# project type guid has been fixed in master and 7.7 - #5864

I think the problem with the F# project type guid is that it is defined in lowercase in the F# addin -

monodevelop/main/external/fsharpbinding/MonoDevelop.FSharpBinding/FSharpBinding.addin.xml

Line 40 in 926494d

<DotNetProjectType language="F#" extension="fsproj" guid="{f2a71f9b-5d33-465a-a702-920d77279786}" type="MonoDevelop.FSharp.FSharpProject"/>

- it should be using uppercase to be consistent with Visual Studio on Windows.
