> .NET: Request attributes for a .Net service.
> --------------------------------------------

> Implement support for passing implicit "request" attributes from the proxy to
> the .NET service.
> {*}Implementation notes{*}.
> # If no caller attributes are passed - there should be no performance
> overhead when executing service methods.
> # Attributes allow only {{string}} and {{byte[]}} values and does not permit
> nulls in key/values.
> # Currently, the context should be immutable, but in the future, it should
> be possible to change it through the interceptor.
> # Context is bound to the NET proxy invocation handler (not to java
> invocation handler) and passed as an implicit parameter on every method call.
> *Public API changes:*
> _API changes are very similar to java part._
> New methods in {{IServices}} to pass caller context to service proxy.
> {code:c#}
> T GetServiceProxy<T>(string name, bool sticky, IServiceCallContext callCtx)
> where T : class;
> dynamic GetDynamicServiceProxy(string name, bool sticky, IServiceCallContext
> callCtx);
> {code}
> New method in {{IServiceContext}} for getting caller context inside the
> service method.
> {code:c#}
> IServiceCallContext CurrentCallContext();
> {code}
> New interface {{IServiceCallContext}}.
> {code:c#}
> public interface IServiceCallContext
> {
> string Attribute(string name);
> byte[] BinaryAttribute(string name)
> }
> {code}
> And the builder {{ServiceCallContextBuilder}} to create
> {{IServiceCallContext}} instance.
