For a Visual Studio project to display tests in the Test View window it needs to be created as a "Test" project. If you want to see the tests and it was created as some other kind of project originally, you should be able to add the following in the element in you
.csproj file which is XML based:


<ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>

The closest I have found on how to do this is:

private static readonly AcceptCommand = Keys.Enter.ToString();

Not only does LINQPad let you do lots of nifty things with LINQ, it also has C# and VB.NET scratchpad facilities all for the low price of nothing (an Intellisense licence for LINQPad is available for a small cost).

This is a nifty poster with the Visual Studio key bindings. It is a good idea to take the time to learn these as it will save you time in the long run.

Do you want to extend the ILog interface to include your own custom logging level?

There is an example of how to do this in the examples that come with log4net. The example creates a Trace level. See examples\net\1.0\Extensibility\TraceLogApp.
