Can I restrict a custom attribute to void methods only?
c#,attributes,custom-attributes,postsharp
Turns out in my particular case there was a solution since I was using PostSharp. My custom attribute inherits from PostSharp.Aspects.MethodInterceptionAspect (which inherits from Attribute) which has an overridable CompileTimeValidate(MethodBase method) method. This allows to emit compiler errors during build time: public override bool CompileTimeValidate(MethodBase method) { Debug.Assert(method is MethodInfo);...
