VS2015 WPF Designer Failed to load FileLoadException HRESULT: 0x80131040

I am creating a WPF project in VS2015, every thing works, even app compiles and runs successfully, but I couldn't load the designer. I am getting the following Exception:

System.IO.FileLoadException Could not load file or assembly 'Microsoft.Windows.Design.Interaction, Version=4.3.0.0, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

Anything else is working fine, just the designer isn't loading up.

Solution

  • Ok So Re-installing VS2015 with Standard Settings did the job for me. Everything is working fine now.

    Cause of issue: I had previously installed VS with custom options and only Web tools selected. That's why few packages were missing. So re-installing with Standard settings did the work.
