I have a windows form that is using a Webbrowser control to view documents on a web server. When it tries to display a TIFF, it just displays a blank screen. It works with other file types just fine. The URL to the TIFF works fine if I paste it into Firefox. Will this flat out not work, am I doing something wrong? Should I invest in a...

Here's the smallest server code example that exhibits this behaviour: using System; using System.IO; using System.IO.Pipes; using System.Text; namespace ConsoleApplication1 { clas...

I've been playing with Code Contracts and I really like what I've seen so far. They encourage me to evaluate and explicitly declare my assumptions, which has already helped me to identify a few corner cases I hadn't considered in the code to which I'm adding contracts. Right now I'm playing with trying to enforce more sophisticated inv...
I've written some tests for .net code that invokes calls to my SQL Server. It appears that using System.Transactions is an excellent choice for rolling back any modifications to the database that result. I'm aware that some purists would suggest that I might want to mock the database, but I'm not going down that road; this is not stric...
