I found the following code for showing the selected item in a treeview when focus has left, but I'm having trouble moving the code to App.xaml so any UserControl could use it.

Hi, I'm trying to write an application which monitors the location of the computer using the .net 4.0 System.Device.Location namespace.

Here is a working ver...

I have IEnumerable<A> and IEnumerable<B> I want to Group Join based on whether A.Test(B) returns true. The keyselector funcs do not seem to do this as the KeySelectors need to return keys of the same type so that they can be checked for equality. Is there something I'm missing here? ...
When creating a Visual Studio Add-In, how can you utilise an app.config for the add-in. If I add one to the project and deploy it then when the Add-In runs and I programmatically try to access it via the ConfigurationManager.AppSettings its not picking up the config file for the add-in. Am I doing something wrong or is there another mea...
Hello, In our C# (.NET 4.0) application, we allocate and de-allocate a lot of memory, in different size chunks. We want to move to an object pool, to improve performance. We implemented an object pool already and saw some performance improvement. We're currently using a stack-based backing store. Other possible alternatives are, queue ...

I have an embedded file - xsd.exe - in my .NET library. How can I, without rebuilding the embedded file from its byte[], use it?
