NCover 1.3.3 + .NET 1.1
I know some organisations aren't ready to deploy .NET 2.0 on their developers' machines. In fact Grant Drake, the author of NCoverExplorer is in exactly this situation. This meant that he wasn't able to use the new 'Test With... Coverage' functionality at work (as it required NCover 1.5.x + .NET 2.0). I have since added support for the earlier NCover 1.3.3. You can now use code coverage on a bare bones installation of Visual Studio .NET 2003 (as of build 1342). Note this will only work with VS2003. If you want to use coverage with VS2002, VS2005 or Express, you must use .NET 2.0 + NCover 1.5.1 (or later)
This is my way of apologising to Grant for leaving him the wrong side of a firewall, with an unfamiliar version control system at 3AM!
BTW, If you're using NCoverExplorer you should read the FAQ that Grant recently put up.
