[SOLVED] NullReferenceException when creating instance of Game class

[Ulisses_Lopez]

i'm retaking a old project that uses XNA 4.0 framework and Visual Studio 2013, now that i can get it work on Monogame and Visual Studio 2015 i got this error, i have read a similar thread error here but it was a problem with a Static Method, this is right after runing the game in Program.cs and Game1.cs files

Exception thrown: 'System.NullReferenceException' in MonoGame.Framework.dll
Additional information: {"Object reference not set to an instance of an object"}

Can you show us the stack trace given by the exception?

Sounds like a Win 8 project.

Maybe you want to just try a MonoGame DirectX Windows project first.

I have solved it, in my case I just had to add the library (Monogame.FrameWork) reference manually with the browse option.
