I want to open files, which are doubleclicked in Explorer, in the same instance of my .Net application, e.g. in a new tab. How can I do this?

For now each file starts new instance of my application. Many programs can open files in the same instance, for example, Opera and Notepad++, so there is an easy way for sure.

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
