Hi all,

I believe the Toolkit would benefit from a nice solution to the following problem:

There should be some quick way to unset UnorderedAccessViews from a GraphicsDevice. Something like device.ResetUnorderedAccessViews().

Of course, in current version someone can do it using code like

        SharpDX.Direct3D11.DeviceContext dc = device;
        dc.ComputeShader.SetUnorderedAccessView(0, null);

But a device.ResetUnorderedAccessViews() would be more handy.

Another alternative is to change EffectPass.ApplyInternal() so that it automatically unsets UnorderedAccessView from ComputeShader if you are trying to bind it as ShaderResourceView.

Typical usecase for this is pyramidal image reduction with compute shaders (e.g. for blur or similar image effects) on dx10 hardware profile using SharpDX Effects framework.

DirectX 10 hardware allows just one UnorderedAccessView to be bound to pipeline. In pyramidal image reduction, one UnorderedAccessView is used as a buffer for results from first stage. Second stage of image reduction algorithm needs to use the buffer from previous stage as input (while using another UnorderedAccessView fro output). If the buffer was bound as UnorderedAccessView, attempt to bind it as ShaderResourceView results in incorrect behavior - zero input for compute shader, but no error or exception. This is very confusing and hard to debug. Some SharpDX exception would be nice in this case. Or some automatic unsetting (inside EffectPass.ApplyInternal) of that UnorderedAccessView.

How should I proceed with possible enhancement? Should I suggest some code, or should I wait for core SharpDX developers to make a decision on this?
