"Unable to load DLL 'Tilengine'

[megamarc]

Oh I see, it's related to the project configuration... I'll have to fix it

1. The Tilengine.dll and SDL2.dll files should be inside the "samples\csharp" directory where the "platformer.csproj" project file resides, not inside the "bin\Debug" temporary folder.
   
2. You have to go to Project properties / Debug, and in the "Working directory" field put the full path to your "samples\csharp" folder. For example in my case it's "D:\Tilengine\samples\csharp".
   

I use Visual C# Express 2010 in spanish so I can't attach a proper screen capture, but I think these options are in the same place in newer releases.

I apologize, please let me know if it works now...
