Problem using ES20.GL on Windows with the AMD ES 2.0 Emulator DLL.

You can find a sample that has been tested to work with AMD's ES emulator here. (This is also available in the Examples.exe application that ships with OpenTK).

Off-hand, you need to pass the GraphicsContextFlags.Embedded flag to the GraphicsContext constructor before using any ES methods (check the GameWindow constructor in the aforementioned sample). The reason is that ES is initialized using completely different code than regular OpenGL - in other words, ES contexts are not interchangeable with regular GL contexts.

same problem here,

I'm using Windows, with the machine mostly same spec as Krisnye
when I tried running ES20 Example mentioned above, I got this exception.

System.PlatformNotSupportedException

I did also copied libEGL.dll and libGLESv2.dll to the folder

Anything else I should try or check?

thx! :)

just for addition, i'm using Vistax64.
the system is working fine on the examples that came with the AMD ES Emulator.

Thanks for pointing that out, so I changed the target machine to "x86" and it got pass that exception.

btw, the story still going on, the application throw
System.NullReferenceException' occurred in OpenTK.dll

at GameWindows.cs, where
(glContext as IGraphicsContextInternal).LoadAll();

Thanks in advance

Thks for your answer Krisnye,

GraphicsContextFlags.Embedded , and [2,0] are passed correctly at the very first place.
Unfortunately still doesn't work :(

Do I have to copy the "libGLESv2.lib" and "libEGL.lib" to anywhere specific?
Or only the DLLs, regarding to ES20 is enough? (to the target Dir, and system Dir)

Thanks again!
