   [XNA] Problem with compiling my own HLSL effect
  Hello. My code is:FileStream fs = new FileStream("ImageProcessing.fx", FileMode.Open,FileAccess.Read);  CompiledEffect compiledEffect = Effect.CompileEffectFromFile(fs, null, null, CompilerOptions.None, TargetPlatform.Windows);  fs.Close();  effect = new Effect(graphics.GraphicsDevice, compiledEffect.GetEffectCode(), CompilerOptions.None, null);and my fx file:float4x4 xViewProjection;struct VertexToPixel{    float4 Position: POSITION;    float4 Color   : COLOR0;};struct PixelToFrame{    float4 Color   : COLOR0;};VertexToPixel SimplestVertexShader( float4 inPos : POSITION, float4 inColor : COLOR0){    VertexToPixel Output = (VertexToPixel)0;   Output.Position =mul(inPos, xViewProjection);Output.Color = inColor; return Output; }  PixelToFrame OurFirstPixelShader(VertexToPixel PSIn) {PixelToFrame Output = (PixelToFrame)0;Output.Color = PSIn.Color;return Output; }  technique Simplest {pass Pass{    VertexShader = compile vs_2_0 SimplestVertexShader();    PixelShader = compile ps_2_0 OurFirstPixelShader();} }It so simple it shouldn't cause a problem yet there is such error:ID3DXEffectCompiler: There were no techniquesID3DXEffectCompiler: Compilation failedWhere is the error?   
  You can't have a pass named "Pass", since "pass" is a reserved keyword.
