It appears that in the 2.1.0 version of the framework, the last argument to the Tao.OpenGL function Gl.glGetShaderSource was turned into an array.

So, instead of:

public static void glGetShaderSource(int shader, int bufSize, out int length, StringBuilder source);

we now have:

public static void glGetShaderSource(int shader, int bufSize, out int length, StringBuilder[] source);

Is this on purpose?

P.S.:

Code that used to work:

int length;
var sb = new StringBuilder( 8192 );
Gl.glGetShaderSource( shader.Handle, sb.Capacity, out length, sb );
// sb contains shader source, length is correct


Code that now no longer works:

int length;
var sb = new StringBuilder( 8192 );
var x = new StringBuilder[] { sb };
Gl.glGetShaderSource( shader.Handle, 1, out length, x );
// sb is empty, length is zero
// notice the 'capacity' parameter had to be changed to 1 to prevent the call from crashing
