By default, WCF offers very limited support for partially trusted clients, and most scenarios require full trust.
In addition, there are several demos showing the IDesign helper classes and base classes that automate configuring security both for the client and for the host.
The enclosed zip contains the installer class that you add to each ES class library project and a short set of instructions stepping you through the creation and configuration of the Setup and Deployment project to create the MSI.
Even though the hosting code may have full trust, you may want to host the service itself in partial trust, to reduce the surface area for attack and to run the service in a virtual secure sandbox.

One way to address that is to chunk up larger payloads into a series of chunks that get sent as individual messages so that if one fails you only need to retry for that single item.
Abort() on the other hand is an ungraceful exit, and it aborts calls in progress, resulting with an error on the client side.
However, using simple aliasing you could provide both the service and the client the overloaded programming model, as shown in the download.
You can compensate for that by including the known type information in the config file, as shown in the download.
They each have to know where the other is, both have to be running to publish or receive events, subscribers cannot subscribe to a type of event, and publishers cannot broadcast an event to subscribers they do not know about.
These can be used outside visual studio from a command prompt which makes them a highly valuable choice in testing environments where web server is either not available or setting it up requires jumping lots of hoops.
The left pane of the WCF Test Client main window lists all the available services, along with their respective endpoints and operations.
The zip file contains a demo client that uses thread local storage both as named slots and slot objects, as well as showing the proper way of doing a clean up.
You should use named pipe binding, and you can even have a single config file for both the client and the host.
The general idea is that the browser notices that you're scrolling to the end and rather than making you click, it'll fetch the next page via AJAX and append it to the page you're already on.
However, at this point, the relay service will promote the connection to a direct connection between the client and the service, by telling the client how to reach the service directly, allowing the client to continue calling the service directly.
When you enter test parameters for a specific operation (or another operation in the same service endpoint) and click Invoke multiple times with the check box cleared, these operations share one proxy and the service status is persisted across multiple operations.
Text properties for almost every control on the form, but doing so requires a lot of mousing around to select the controls, then the appropriate property in the Properties window, and then you repeat over and over for each control.
VB will let you overload interface methods, by default, WCF will not let you overload contract operations.
It shows not just one network but a hierarchy of networks of actors, how messages flow across the networks, the fractal nature of most actors meshes, and how to set up the mesh of actors.
Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support.
