The picture below shoes the feature in action, notice the parameters are available now:

The other interesting thing is that the current goal is to get 80% unit tests passing on all projects (the projects that I work on have 100% all the time, otherwise I would lose my mind).  This is a strategy I disagree with.  Let’s say that over time your project has gotten to a state where you only have 50% of the unit tests passing.  As far as I am concerned, this is equivalent to having 0% of the tests passing.  Why?  Because developers see tests in two colors: red and green.  You will quickly find that the 50% will continue to down because no one is actually noticing that they are breaking tests as they are making code changes.  On a few large projects I have worked on, I have seen where a single failing unit test quickly becomes 20. 

Assuming that because of business goals and quantity of tests to fix, that just fixing all of the tests immediately is not an option.  A much better strategy, in my opinion, would be to ignore the tests that are failing and say that all projects must have 100% unit tests passing.  Then, make your goal to be to work your way down from 50% ignored tests to 0% ignored tests over a reasonable period of time.

unable to resolve host mymachinename

 

After a bit of searching, I landed on this bug which apparently has affected a number of people:

Using ‘gksu gedit’ and fixing /etc/hosts solved my problem.  To get Internet connectivity back, I had to disable IPv6:

    I really only wanted to know one time that Visual Studio 2008 was released today and not have to deal with the inevitable flood of posts on the topic for the remainder of the week.
