Decrease Solution from Visual Studio 2017 RC to Visual Studio 2015

I had a project in VS 2015 Update 3 with a lot of code logic. I successfully upgraded it to VS 2017 RC. The implementation of the code continued until it reached the point where the VS 2017 RC showed many problems and instabilities, for example .. Net Core DLL template was deleted! installer or resource file cannot be compiled and so on! I would like to return the solution to VS 2015 in order to work flawlessly, but this is not possible easily due to the large amount of code implemented in VS 2017, except for the new Roslyn features. Any suggestions on how to perform the demotion?

This is truly a manual process, and there are no tools that could automate this.

I had the same problem and fixed it with this solution: 1) create a solution to any project you want (winforms, etc.), 2) find the project folder and find the .sln file. 3) open it using notepad. 4) copy the first 4 lines as shown here .

5) find your .sln file for the project you want to downgrade. for example: foo.sln (its found where your project is located). 6) open it with a notebook and insert lines instead of the first 4 lines 7) save and open sln. he must open it under visual studio 2015

Hope this works for you.
