Some days back I had pointed to the blog by Beatriz on how to debug WPF data binding errors. I have been using the PresentationTraceSources.TraceLevel feature (available with .NET 3.5) since then and have found it very easy to use and very effective in resolving my data binding errors.

However recently when I opened a XAML, which had this debugging feature enabled, in Expression Blend 2.5 March Preview, I got an error. The XAML won't open in designer and showed "Invalid XAML" with details as 'The member "TraceLevel" is not recognized or is not accessible'.

Recently while supporting a project on converting their WPF application for globalization and localization support, we faced an issue in being able to work with Expression Blend 2 Dec preview. We used the recommended approach for globalization and localization and after doing all that Expression Blend failed to load the user controls in design view.

You would get an error like this - "MissingSatelliteAssemblyException: The satellite asembly named yourassemblyname for fallback culture 'en-US' either could not be found or could no be loaded. This is generally a setup problem. Please consider reisntalling or repariring the application."

Further to my unit testing experiments that I have been blogging about in the last few days, I was playing around with the DashCommerce starter kit. After installing and configuring the site, I started by creating some tests for the code in the App_code folder.

The test creation was successful and I was all set to run. But luck was against me and I got compilation errors regarding missing namespace. As I had mentioned in my earlier blog, the testing happens via private accessor and since its creation happened successfully, ideally I shouldn't  have had a need for adding explicit references and namespaces to my test project.

BizTalk Server 2006 R2 is now available. Introduction paper to this version is available here. Get a trial version of it from here. MSDN Subscribers can download it from the MSDN Subscribers download site. The latest documentation for this version is available here.

I had earlier blogged about getting BizTalk Server 2006 to work in Vista. At that time BizTalk wasn't officially supported on Vista, but I had wanted to test if it worked or not. The current R2 release is now officially supported on Vista. So I decided to give it a try again. I used BizTalk Server 2006 R2 Developer Edition and worked on Windows Vista Ultimate.

One argument why some consider Linux to be more secure than Windows is that – hacking attempts on Linux are far lesser than Windows. Well, you are only true, until you are proved otherwise. And there is nothing in this world as “Completely Secure”. Everything is only secure until it is broken.

Earlier today a colleague asked how do Services and Applications talk to each other in Vista and I said, "the way they used to earlier". I wasn't aware of Session 0 and Session 1 concept till now. He pointed me to this MSDN article that explains what this new concept of Session 0 in Vista is all about.

This essentially is to prevent direct access to services from applications and thus prevent hacker to elevate their own security priviledges. Some information around this is here and on this Channel 9 video. A white paper on impact of session 0 on services and drivers is also available.

[Edited April 16, 2007] Found some tips to communicating with Session 0 services here.

Recently while working on my Vista machine, I was was working on a ASP.NET Web site and I wanted to have a colleage of mine have a look. Like always, I mailed him the URL and waited for him to view it and get back. To my surprise, he reverted stating he can't view it.

The error he was getting was "Internet Explorer cannot display the webpage". This was surprising since I was able to view the site locally on the Vista machine without any issues. This meant that IIS was configured and running properly.

In the  "Roaming Profiles Implementation for SoftGrid-I" we discussed the concept of Softgrid roaming profiles for applications and it's contribution in achieving a true roaming user profile.

I will continue the discussion further and discuss a simple procedure to implement Softgrid Roaming profile in a test lab.

Normally in a locked down environemnt in order to enable End Users (EU) to customize application specific settings and other customizations application packagers identify and elevate security permissions to secure NTFS and Registry areas. This is often considered as a security risk and also contributes to effort in troublershooting and identifying such areas on the local system.

SoftGrid eliminates the requirement of elevating security permissions to the restricted area. As Softgrid virtualized applications execute within a virtual environement the user has complete access to the virtual environemnt while executing the application. The advantage is that the users have access to the desired functionality withoutaffecting the state of the host system.

Recently when working on an application, I was playing around with writing custom http handlers. There is nothing new in that lots has been written about how to build and configure custom http handlers. So when after writing this I decided to configure it in IIS 7 on my Vista machine, I was pleasently surprised to see that I was lost !

IIS 7 UI has changed noticeably from its earlier versions and when I wanted to configure the file extension I wanted my custom handler to work with, I didn't know what to do.
