castle-dynamicproxy

I was asked to implement castle dynamic proxy in my asp.net web application and i was going through couple of articles which i got from Castle Project and Code Project about castle dynamic proxy in asp.net web application.... Both articles delt with creating interceptors but i can't get the idea why interceptors are used with classes.... Why should i intercept my class which is behaving properly? Aaronaught Let's say that your class needs to do 3 things for a certain operation: Perform a security check; Log the method call; Cache the result. Let's further assume that your class doesn't know

I'm using Castle DynamicProxy to add an interceptor to my types. Now I need to get the underlying base type (NOT the proxy itself). I found a few hints on SO that suggested to use the ProxyUtil class like this: object realInstance = ProxyUtil.GetUnproxiedInstance(proxyInstance); This does not seem to work as bool isProxy = ProxyUtil.IsProxy(realInstance); is always true. I also tried using the following code snippet, which is essentially what ProxyUtil is doing: var accessor = proxyInstance as IProxyTargetAccessor; var realInstance = accessor.DynProxyGetTarget(); with the same results,

My questions is related to this post Intercept the call to an async method using DynamicProxy I want to implement interceptor that works with async methods that returns Task or Task<T> result. I use next code for return ContinueWith result (in order that caller method wait while interceptor finishes work) var task = invocation.ReturnValue as Task; invocation.ReturnValue = task.ContinueWith(c => { code that should execute after method finish }); Above code works fine for Task result, but in case of Task<T> result ContinueWith will change return type from Task<T> to Task . I need to call
