Postsharp introduce Attributes with Property Arguments

I am trying to achieve attribute introduction like here but my attributes have property arguments like: [Foo(Bar = "Baz")]

How do I correctly pass the arguments? I'm not copying the attributes from something else, so I don't think I can use CustomAttributeData?

You can set properties of your custom attributes by using ObjectConstruction.NamedArguments dictionary.

For example:

public IEnumerable<AspectInstance> ProvideAspects(object targetElement)
{
    Type targetType = (Type) targetElement;

    var objectConstruction =
        new ObjectConstruction(typeof (MyCustomAttribute).GetConstructor(Type.EmptyTypes));
    objectConstruction.NamedArguments["Bar"] = "Baz";

    var introduceAttributeAspect = new CustomAttributeIntroductionAspect(objectConstruction);

    yield return new AspectInstance(targetType, introduceAttributeAspect);
}
