You can only marshal pinned delegates that have blittable types.  The following reference MSDN article talks about blittable and non-blittable types.

Why are you using the delegates, instead of passing the arguments to the p/invoke declarations directly?

I was able to solve my problem with the following code:
 Dim x_dim As Single = WorkC(1) * 0.5
        Dim y_dim As Single = WorkC(2) * 0.5
        Dim z_dim As Single = WorkC(3) * 0.5

        Dim vertices() As Single = { _
        x_dim, y_dim, z_dim, -x_dim, y_dim, z_dim, -x_dim, y_dim, -z_dim, x_dim, y_dim, -z_dim, _
        x_dim, y_dim, z_dim, x_dim, y_dim, -z_dim, x_dim, -y_dim, -z_dim, x_dim, -y_dim, z_dim, _
        x_dim, y_dim, z_dim, x_dim, -y_dim, z_dim, -x_dim, -y_dim, z_dim, -x_dim, y_dim, z_dim, _
        -x_dim, y_dim, z_dim, -x_dim, -y_dim, z_dim, -x_dim, -y_dim, -z_dim, -x_dim, y_dim, -z_dim, _
        -x_dim, -y_dim, -z_dim, x_dim, -y_dim, -z_dim, x_dim, y_dim, -z_dim, -x_dim, y_dim, -z_dim, _
        x_dim, -y_dim, -z_dim, -x_dim, -y_dim, -z_dim, -x_dim, -y_dim, z_dim, x_dim, -y_dim, z_dim}

        Dim indices() As Byte = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, _
                                 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}

        Gl.glEnableClientState(Gl.GL_VERTEX_ARRAY)
        Gl.glVertexPointer(3, Gl.GL_FLOAT, 0, vertices)
        Gl.glDrawElements(Gl.GL_QUADS, 24, Gl.GL_UNSIGNED_BYTE, indices)
        Gl.glDisableClientState(Gl.GL_VERTEX_ARRAY)
