The past two days I have been working on a performance problem we were having with a workflow implementation. The workflow was quite simple, A WCF call coming in, then registering the request data in a SQL database and return a ticket that the request was received. The ticket can be used by people to get information later on the status of their ...

Today I had to upgrade several machines from the Beta or RC version of VSTS to the RTM version.You must manually uninstall all artifacts installed during the Beta period and that can be a daunting task. Therefore I created a script you can run to uninstall all of the stuff in one sweep. Just copy the following lines, place them in a command file ...

The past few days I have been working on Load and stress testing some workflow implementations that work with the WCF input activities I created (I published them at Codeplex for you to use as well http://www.codeplex.com/WCFWorkflow )This project has some very interesting non-functional requirements where we need to process more than 300.000 ...

The past few weeks I have been working on writing a new training on windows workflow foundation. Last week we did an internal dry run of the content and as we speak I am working on the hands-on labs that accompany the course.During the development of the labs I ran into an interesting struggle with the activity binding dialog when you try to ...
