i have a problem with BlendState, before insert the following codes everything works fine in my app but after setting codes everything in my rendering panel disapear.
i test the app with PIX after inserting the codes, ShaderResources,VertexBuffers,IndexBuffers and every thing was ok!!!!
var des = new BlendStateDescription {IndependentBlendEnable = false};
Context.OutputMerger.BlendState = BlendState.FromDescription(Device,des);
why???
