Soliving: Visual Studio 2013 U1 Lightswitch – March 2014–Can’t create project (.lsxtproj) is not supported.

After updating the SQL Server Data Tools in Microsoft Visual Studio 2013, creating a LigthSwitch project will result in an error: ‘…\Application1.lsxtproj’ cannot be opened because its project type (.lsxtproj) is not supported by this version of the application. To open it, please use a version that supports this type of project.


I installed everything regarding the SQL Server Data Tools and after restarting Microsoft Visual Studio 2013, I could create a LightSwitch project again.



On my development machine: “Micrososft Office Developer Tools for Visual Studio 2013 – March 2014 Update” is installed.

    I’m facing the same issue, but dont understand your solution. What do you mean by “I installed verything regarding the SQL Server Data Tools” ? Is there any special version you need to install ?

    Can you provide us with a screenshot of components, you think are related ?

    Thanks in advance,

    Just to update:
    If “.lsxtproj is not supported” error still remains after installation of SQL Server Data Tools and MS Office Developer Tools for VS2013 – March 2014 Update, try to install Visual Studio 2013 Update 5. That helped me to solve this error.
