I have created a texture with the following description. When I call the AsSurface() method on the texture, I get an error stating

'E_NOINTERFACE: The requested COM interface is not available'

Texture2DDescription description = new Texture2DDescription

{

ArraySize = 1,

BindFlags = BindFlags.None,

CpuAccessFlags = CpuAccessFlags.None,

Format = _format,

Width = _width,

Height = _height,

OptionFlags = ResourceOptionFlags.None,

Usage = ResourceUsage.Default,

SampleDescription = new SlimDX.DXGI.SampleDescription(1,0),

MipLevels = _levelCount,

};

I am not using Direct2D, or older versions of Direct3D. Just Direct3D 11 and DXGI.

What are the conditions that cause this error for the AsSurface() method?

Thank you for your help.
