VisualStudio 2015 version information

When creating a new "Class Library (Xamarin.Forms)" project with belonging new solution the created project always has the same GUID: 67F9D3A8-F71E-4428-913F-C37AE82CDB24

You can also find some public repositories referring this GUID.

VisualStudio version info: see attachment

- start Visual Studio 2015
- on "start page" select "New Project..."
- select "Installed > Templates > Visual C# > Cross-Platform > Class Library (Xamarin.Forms)"
When inspecting the created *.csproj file or the *.sln file, the project always gets the same GUID:

- we have a master solution with a PCL UI project.
- other sub solutions shall refer to the projects of the master solution (done by importing those projects into the sub solution
- when using those sub solutions, the sub solution detected the duplicat GUIDs and changed the GUID of the master-project.
- when using the master solution, the GUID of the master-project was changed back again.
- during check in into GIT these GUID changes were observed again and again.

- create the project and solution as described above
- delete the project in the solution
- delete the project folder in the file system
- create the project within the solution again via "Add > New Project..."
