Issues with VS2017 and monogame in winform

I have a windows form project that I have a picturebox that I am using as the draw surface that runs just fine in VS2015, I open it in VS2017 and it throws an error when it is passing the intptr of the drawing surface.

System.IO.FileNotFoundException: ‘Could not load file or assembly ‘System.Runtime.WindowsRuntime, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies. The system cannot find the file specified.’

When checking the intptr, it looks like it hasn’t been assigned anything yet. I tried this on another computer using VS2017 and it gives the same error.

Thanks for any help!

Finally figured it out… Referencing the wrong dll, it was grabbing the one in the Windows8 folder, I have to remove it and then browse to the one the Windows folder.
