      • Enable transferring large messages easier

        so that I do not have to restart when a connecton is aborted during transfer between or I can cancel a transfer in between.

          • Local binding

            Why can't we have a local binding for services to run in-process on a machine instead of using net.pipe?

            • Easier way of doing dependency injection (alternative to IInstanceProvider derivations)

              Even though WCF Web Api is now renamed to ASP.NET Web Api, the model on how to do dependency injection should be adopted by WCF as well.

              • Open-source WCF OData Services

                WCF OData Services contains a lot of classes that can be used to dynamically build WCF OData filters, build expressin trees based on a string, ... However, it's not feature complete and no progress is being made on this. Open-sourcing it may help expose several hidden treasures as well as get developent further.

                • Better settings Documentation

                  Describe what each of the settings do and how they interact with each other from a client vs. server setting. For example: how a timeout value in the client config does or doesn't work with the same setting on the server.

                  • Moving to convention over configuration

                    Name contract interfaces as ISomethingContract, and drop the need to have [OperationContract] for each method - default should be exposing the method, unless specified otherwise (such as [NonServiceOperation]

                    • Developer-friendly custom transport channel extensibility

                      As for me writing custom transport channel now is a pain. Example in WCF Samples with local channel contains huge amount of hard to understand and maintain code. A lot of AsyncResult subclasses makes code unreadable. Most of the blog posts on that theme are outdated (2007, 2008 year). MSDN contains just short explanation what this method do, but there is no good source to build solid view on how it works, why I should use that complex pattern, and so on...

                      • Alternative to statics (OperationContext.Current et al)

                        Mainly for testability - it should be able to inject the context into your service instance.

                        • Real contract first

                          WCF should allow implementing SOAP services with contract first, meaning WSDL & XSD. Xml Serializer needs to be able to understand Xml Schema standard better (e.g. maxOccurs, minOccurs, etc) and allow exposing the initial schema instead of generating schema from code in runtime.

                          • Publish documentation of the JSON endpoints created from a WCF domain source.

                            Publish documentation of the JSON endpoints created from a WCF domain source. Trying to produce a javascript application using WCF on the server is next to impossible without knowing what the endpoints are. We need to know the endpoint signatures and how to build changeSets to talk to them.

                              • Propagate [obsolete] attribute in client proxy generation.

                                Service changes all the time, and sometimes, you have to move on an depreciate obsolete method/properties.

                                It would be great if we can generate/post-process the proxy so that we mark obsoleted proxy method/properties with the obsolete attribute. That can make the depreciation process easier.

                                  • Better java interoperability

                                    We use WCF 4.0 / WIF 3.5 WSTrust1.3. This works great with .NET clients. It is is a beast to get working with Java. The perception is that .NET WCF services are not interoperable with Java. Java samples /HOWTOS would go along way to squash this idea.

                                    • Make Operation.Context work with async

                                      Currently WCF's Operation.Context does not work when you use the async and await keywords. It would be great if this could be supported in the next version.

                                      • Better Logging for non-XML messages

                                        When using diagnostic tracing all messages appear as XML in traces even if they are transmitted / receieved in non XML format, e.g. JSON. I believe being able to log the actual bytes sent and received from the diagnostic traces and programmatically from a logging extensibility point would be a good improvement.

                                        • Surface WIF active federation bindings in Svc Config Tool

                                          I am not sure if this has already been enabled (as far as I know it has not). The active federation bindings - WS-Trust do not show up in the Svc Config tool. These can be complicated to setup and it would be easier with config tool options for this.
