Error when opening an ASP.NET Core project with Visual Studio 2015 after installing Visual Studio 2017 RC : The following error occurred attempting to run the project model server process 1.0.0-preview4-004223

January 22, 2017

Ok so if your like me and tried installing Visual Studio 2017 RC, you were probably astonished at how fast it installs compared to previous version of Visual Studio. But as impressive at it is at installing, I ran into some compatibility issues with Visual Studio 2015, so I had to uninstall Visual Studio 2017 RC.

Now even with Visual Studio 2017 RC uninstalled, I ended up running into an issue when I was trying to open a  new or existing ASP.NET Core project. Here is the error I would get when trying to open my ASP.NET Core projects in Visual Studio 2015:

The following error occurred attempting to run the project model server process 1.0.0-preview4-004223

To resolve this, I had to go to directory “C:\Program Files\dotnet\sdk” and delete folder “1.0.0-preview4-004233” as shown here:

This then resolved my issue when trying to open an existing or new ASP.NET Core project in Visual Studio 2015.

Enjoy!
