This always happened while developing a web application in Visual Studio 2005 and wanting to use code that deals with certificates. During development Intellisense would find the System.Security.Cryptograph... namespace just fine. But it couldn't be found at runtime.

A plea out to all those who are using ASP.NET AJAX with sites on IIS7, either under Vista or Longhorn Server: I've been battling a strange issue with ASP.NET AJAX on IIS 7 running under Vista. It's a site that was upgraded from RC1 to RTM, and works great under IIS 6. Have troubleshot it enough under IIS 7 to determine that if the AppPool has the Managed Pipeline Mode set to "Integrated", it fails, and if it's set to "Classic", it works perfectly. The error I'm getting is one that was common during...

Did you know that there's no grid-like control in WPF 1.0? This post will show you how to get around that limitation. But first, may I say that the recently-released Orcas September CTP bits offers a great improvement at design-time when writing WPF applications. Instead of those three clunky tabs for .xaml, [Designer], and .xaml.cs that we had back in the June CTP, you now get the first glimpse of Microsoft's new cool “Split” view, which will become a part of ASP.NET in the Orcas timeframe! Very...

Dreamweaver has always offered a compelling environment to develop HTML-centric web pages, with some server-side tricks thrown in for good measure. Historically Visual Studio has offered the opposite, great server-side but a bit light on the client-side code. Visual Studio 2005 brought many enhancements that close the gap. A month ago a friend and I finished a project and submitted it to Microsoft that compares the experience between those two. So if you ever wanted to see how things are done in...

Where I work there's a firewall application required in some parts of the network that doesn't play nicely with XP SP2. So we're still on SP1 while the vendor sorts out the problem. Meanwhile I still need to get work done, and I would much rathar be doing that work on Whidbey than Everett! When trying to install Whidbey, it halts with a notice that SP2 is required to continue the installation. So I discovered a hack to get the application installed on XP when SP2 isn't onboard. Obviously this is...
