  • Blog Post: Third Party ASP.NET Controls and Visual Studio 2008

    We've had a few cases recently where customers are using third-party ASP.NET server controls (either written by a third-party company or by the customer) and finding that the controls are not rendering correctly in the Visual Studio 2008 design surface. Most recently, we had an issue where a popular...
  • Blog Post: Error When Opening ASP.NET Site on IIS 7 Using Visual Studio 2005

    Now that Windows Server 2008 is out the door, we're starting to see more customers using IIS 7. I recently worked on a case where one of our engineers was dealing with a customer using Visual Studio 2005 and IIS 7. He was encountering an error message when attempting to open his ASP.NET 2.0 application...
  • Blog Post: New Hotfix: Run ASP.NET Without Full Trust in My_Computer_Zone

    I have been working with the product group on a new hotfix that allows you to run ASP.NET 2.0 applications without associating the My_Computer_Zone code group with the Full Trust permission set in Code Access Security. The new hotfix is available now under KB article 943598 . Pay careful attention to...
  • Blog Post: Long Delay on First Request to ASP.NET 2.0 Application

    I have worked several issues recently regarding long delays on the first request to an ASP.NET application. These delays are much longer than typical app domain startups and JIT compiles. To troubleshoot these issues, I get hang dumps of the process to see what's going on. In those dumps, I can see that...
  • Blog Post: Running ASP.NET in a Shared Hosting Environment

    I was recently working on an issue with a large international hosting company. This company hosts many websites in a shared hosting environment, and one of their customers had uploaded a page that performed some tasks using ASP.NET that greatly concerned them. The ASP.NET page allowed the following when...
  • Blog Post: Automating aspnet_compiler in Visual Web Developer

    Visual Studio has a cool user interface for publishing a website using the Publish Web Site dialog, accessible by selecting Build, Publish Web Site. You can use this dialog to pre-compile your website and avoid having to deploy source code. Visual Web Developer Express doesn't offer this dialog, but...
  • Blog Post: ASP.NET Version Madness

    With the impending release of Visual Studio 2008 and Visual Web Developer 2008, along with the .NET Framework 3.5, there is a bit of confusion around version numbers for ASP.NET. Before I get too far into this, let me just say right now that this post has little hope for clarifying things too much, but...
  • Blog Post: Why don't my .NET Framework patches install?

    I recently worked an issue with a customer who was rolling out some patches to over 50,000 computers across his enterprise using SMS. SMS reported that the patches successfully installed on all workstations, but my customer noticed a strange anomoly that he couldn't explain. Even though SMS reported...
  • Blog Post: Visual Studio 2008 Beta 2 Available - Now with VWD 2008

    We recently announced the RTW of Visual Studio 2008 beta 2. What you might not know is that beta 2 also introduces the new Visual Web Developer Express Edition 2008. ASP.NET developers should be pretty excited about the new features, and this product will be available free once it RTMs. You can download...
  • Blog Post: Free VWD and SQL Server 2005 Express Hosting (For 30 Days)

    If you're just getting around to checking out Visual Web Developer (whether as part of Visual Studio or by using the free Visual Web Developer Express Edition,) you might want to test out your application in a real-world hosting environment. Then again, most developers don't ever test anything, so why...
  • Blog Post: March CTP of Orcas Has Arrived

    A short while back, I blogged about the great new features in Orcas that ASP.NET developers will enjoy thanks to the incorporation of the Expression Web designer into Visual Studio. At that time, these features were set to debut in the February CTP version of Orcas which was slated to release in March...
  • Blog Post: Getting to the Root Cause of SqlExceptions

    It's pretty common for me to work cases where something bad happens when an ASP.NET application is accessing a database. The nature of my job dictates that troubleshooting on these applications is most often performed in a production environment via post mortem debugging. Fortunately, our toolset for...
  • Blog Post: A Train or a Beast

    Expression Web is Microsoft's latest web design tool. It should be no surprise to you that we put a lot of effort into making sure that Expression Web supported the design-time elements of ASP.NET 2.0. Doing so has proven to be a double-edged sword. On the one hand, a lot of ASP.NET developers who have...
  • Blog Post: Orcas - Not just blowing air!

    I haven't blogged in a long time, partly because I've been very busy with other things, but mostly because I made the mistake of making this a debugging blog when I started it. Little did I know that one of the most prolific technical bloggers the world has ever known had already started a debugging...
  • Blog Post: The Infamous Debug Attribute

    Our most common issues deal with memory problems. Memory problems come in many flavors, but one of the more common ones is the OutOfMemory exception or OOM. A lot of the OOM issues we see are due to high memory conditions, but some are not. When an OOM condition is not accompanied by high memory usage...
