The question is whether this behaviour is by design or a bug results from unexpected interaction between IIS and .NET Framework 3.5. To my understanding, D...

I'm extending the Aero glass frame into the client area and want to place a search box on the extended frame, just like it Windows Explorer does: The default WPF text box has a grey/blue border though, and not the dark, white glowing border that can be seen on the screenshot.

I have a simple, horizontal <Line> element. This line has a RotateTransform applied to it, which slants the line at whatever angle I choose.

Where I work I see a lot of otherwise very talented C++ developers produce ugly C# code, purely because they are not as familiar with the .NET framework and the features of C#. Now I only started programming relatively recently, but already wheras I am very familiar with .NET 2.0 I find myself rarely (if ever) using any features of .NET...

It's working great on my development machine, but now I need to know how to deploy it on the user's machine. Click Once isn't available for this kind of project, so I guess I'm stuck with manually distributing the DLL. So, where...
