[Clojure-CLR] implement interface that has properties
I'm trying to implement an interface that has properties but can't quite seem to get it to work and I also have not found any relevant examples via Google (yet). I'm sure I'm doing something completely wrong here but have no idea how to fix it. (System.Reflection.Assembly/LoadWithPartialName System.Web) (defn foo-handler [] (reify System.Web.IHttpHandler (IsReusable [] false) (ProcessRequest [context] ( IsReusable is a property and I don't know how to tell reify that it is not a traditional function.

Re: [Clojure-CLR] implement interface that has properties
If I recall, properties are just syntactic sugar for awkwardly named methods. Have you tried the compiler-generated get and set method-names?

Hi John, Yes I've tried adding get_ to the property name but I'm still not doing something correctly.
