jchand99 commented 6 years ago

Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at OpenGL.Gl.DeleteTextures(Int32 n, UInt32[] textures) at OpenGL.Texture.Dispose(Boolean disposing) at OpenGL.Texture.Finalize()

That is the error message recieved.

Hey there,

Did you end up resolving this issue? For posterity, do you mind including your solution in this issue?

Thanks!

Hello Giawa, I seem to have run into the same problem using Visual Studio 2019 and the example code in a console application. It happens when the application is closed and i am not sure but when I try to step into the Delegates.glDeleteVertexArray(n, arrays) function I get the System.AccessViolationException. Since Delegates is a class of internal delegates I have no idea where they are pointing to. Since jchand99 has not published any solution I am a bit in the dark here about what is happening.

Could you please be of any assistance?

With regards, Michel

P.S. it seems to start acting up when I add the line for the new ShaderProgram. If I don't attach those and not paint the cube nothing is wrong. If I add the line for the ShaderProgram it gives this exception. I don't need to draw the cube to trigger it.
