When trying to open Project Solution in Visual Studio, nothing is being loaded.


You may get the following error:



  • The solution could be opened before.
  • This may occur if you have recently performed an upgrade on your client components.
  • Creating a new K2 Project and workflow also resulted in the same issue: blank windows, with nothing being shown in Solution Explorer.

Troubleshooting Steps

To resolve this, please do the following:

  1. Run the following command on your Visual Studio command prompt:

    devenv.exe /resetsettings

  2. If the above does not work, then delete or rename this folder and restart Visual Studio:

    C:\Users\{your username}\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache

    The version of Visual Studio you have is specified by the number.
    Visual Studio 2013 is 12.0
    Visual Studio 2015 is 14.0
    Visual Studio 2017 is 15.0
