    Dear community!

    I'm a student in high school, and my school uses the Visual Studio 2010 softwear and in my computer the 2015 version is installed and this situation is really inconveniet because I don't know what the new version does but when I try to open my home project at my school it's just gives me a full list of endless errors and warnings!!

    I found out that in the .Config file was added a line of .NetFrameWork something that propablly limiting the old version to open and run my projects( I tried to delete this line and the old version in my school succeeding to run the project but still it give me other warnings of other files in the projects).

    So I wanted to ask if there's a way of saving my project somehow that Visual Studio 2010 will open and run them without any problems?

    Thank You very much.

    Hi Amit Yeffet,

    We often can't open a high version of Visual Studio project with an low version of Visual Studio directly. But we can use high version Visual Studio to open low version Visual Studio project.

    If you want to open VS2015 project in VS2010, please try with following workaround.

    1. Create a new project with VS2010. Then copy the various components in your VS 2015 project into it.
    2. Open the .sln file with Notepad. You could see the version of Visual Studio in .sln file as below. Then modify the Format Version 12.00 to 11.00 and the Visual Studio 14 to Visual Studio 10. Save it and open the project with Visual Studio.

    Best Regards,
    Weiwei
