One of the boasts I've heard of unit testing is that you can run 2000+ tests in a minute or so.. because the only limit is cpu speed and ram. I, however like to include external dependency assertions/testing in my test projects (such as: does the user account the application logs on with have insert/update/delete permissions on the appr...
I am looking into using a side bar menu option. This will only be displayed on some aspx pages. Can I insert in the site master, with a toggle condition, or do I go the tedious route of adding menu.ascx on each aspx page?

I watched the DNR TV episode with Glenn Block and it looks like MEF would be useful for my company. I am trying to find out more information on it's strengths and weaknesses and some sample projects that use it. Are there any good blogs/tutorials on using MEF? Note: I use C#, so if the examples are in C#, that would be awesome. ...

I am thinking about a plugin model for my client-server application. A plugin will have a UI part(for configuration, runs on client) and an execution part(does the work, runs on server).

I have implemented a queuing mechanism including UI for running specific types of workflows (WF 3.5), where I wanted to include a possibility for a user to cancel / terminate the workflow.

I recently bought Ayende's book Building DSLs in Boo (buy it, read it, it's awesome) but I'm coming up against an implementation problem and I want to see what the generated code looks like. I would normally use reflector to look at the code but in this case the assemblies are dynamic and only in memory. Is there a way to save dynamic ...
