I have some code created in 2010 I'm trying to bring to life. The source didnt include slimDX.dll so I have to use the latest. I get errors on ShaderBytecode as its not in the the same namespace anymore. also this line
_effect = new Effect( D3D11Device, _effectBytecode, EffectFlags.None );
no longer takes the 3 parms
I tried adding the D3DCompiler and omiting that last parm ( and it compiles ) but that crashes the app on MapSubresource
"E_INVALIDARG: An invalid parameter was passed to the returning function (-2147024809)"
Here is the source I'm having troubles with.
