In one of our projects we had to transfer large data from the server to the client WPF application. In the beginning we had some performance issues. Therefore we decided to do some comparisons between ASP.NET Web API, WCF (with and without protobuf-net). The configuration: ASP.NET Web API WCF (Protobuf) WCF – Protobuf serializer –… Read More »
In one of my projects (WPF, WCF) we are working with server and client side entities. Although the entities look very similar, we had some reasons to separate them: – Client side entities require more logic -> Implementation of INotifyPropertyChanged -> Implementation of IEditableObject -> Restore handling (When user cancels edit) All these functionalities were… Read More »
If you never heard about the “Onion Architecture”, you should read Jeffrey Palermos blog post. He’s the Onion-Architecture-Guru 😉 I created a very small demo VS.NET solution, which shows how I would apply this type of architecture in a project. (The download link is at the bottom of this post.) The following graph displays the… Read More »

Routing can be used for multiple purposes: – Service versioning – “Extended” load balacing – Content-based routing scenario – Service partitioning – Protocol bridging – etc. In this example, I have two person services. One in London and one in Paris. The client knows only the… Read More »

Running a WCF service (svc) with basicHttpBinding and Https needs some configuration inside the web.config. First create a website for your service in IIS with a Https (port 443) binding. For this example, I created a test certificate with makecert.exe. Now develop your WCF service with default ABC-configuration (Binding = basicHttpBinding). Open the the service… Read More »
With DataTables you have the ability to set a Error Message per Row. This is useful, when you want to display i.e. the Validation Errors in the GUI. In a 3-Tier Application your client communicates with the Application Server via Services. Exchanging DataTables in a .NET Application works well. But if your services are used… Read More »
For hosting WCF Services in IIS you usually need a .svc file. This File exposes your Service. With ASP.NET virtual Paths you have the opportunity to load your service without a .svc file. You can put the WCF Service inside a DLL without adding a reference to the ASP.NET WebApp. Implementation: – Create a Class… Read More »
