Exception: Vertex buffers are write-only on OpenGL ES platforms #1

Hi! I've tried to get data from compute buffer on my android device and got this:

android.runtime.JavaProxyThrowable: [System.NotSupportedException]: 
Microsoft.Xna.Framework.Graphics.BufferResource.PlatformGetData(Unknown Source:0)
Microsoft.Xna.Framework.Graphics.StructuredBuffer.GetData(Unknown Source:0)
Microsoft.Xna.Framework.Graphics.StructuredBuffer.GetData(Unknown Source:0)
MyStructuredBuffer.GetData(Unknown Source:0)

On a windows build everyting works well. As far I know GL ES 3 supports getting data from buffer and this is just old xna code interfering.

Thanks for reporting. I'll have a look at it when I find some spare time.
