With the work I’ve been doing on versioning I’ve had to write unit tests that verify the behavior I expect from the helper classes in Microsoft.Activities.dll .  If you want to verify that your assembly versioning strategy is working correctly you may have to do similar testing.  This sort of testing is tricky… in this post I’ll share with you my solutions to some tough problems. Test Problem: Multiple Versions of the Same Assembly in a Test Run There is only one deployment directory for...

Een nieuw jaar betekent, zoals gebruikelijk, weer nieuwe plannen. En voor de DotNed gebruikersgroep is een van deze nieuwe plannen om een podcast te gaan maken en publiceren. Deze DotNed Podcasts worden speciaal voor de Nederlandse .NET ontwikkelaar gemaakt en zullen dan ook zo veel mogelijk Nederlandstalig zijn. Het is de bedoeling dat de onderwerpen die we gaan behandelen heel divers zijn, zolang het maar interessant en relevant is voor een .NET ontwikkelaar. De eerste van deze serie podcasts staat...

This blog reviews the current (January 2011) set of options available for hosting existing .NET4 Workflow (WF) programs in Windows Azure and also provides a roadmap to the upcoming features that will further enhance support for hosting and monitoring the … More » Blog Post by: Suren Machiraju

Never assume anything, test everything All these years I assumed that Assembly.Load() would respect version numbers if specified in the FullName string.   As I’ve been adding more test coverage to Microsoft.Activities I found that Assembly.Load does not work that way. Suppose you have an assembly named ActivityLibrary and you deploy V1 but you try to load V2 // This call will succeed and happily load V1 if it finds ActivityLibrary.dll Assembly.Load( "ActivityLibrary, Version=2.0.0...

In my previous post , I’ve been exploring how changing the version of an ActivityLibrary affects a workflow.  In this post I want to explore how Workflow Services behave. The good news – as far as I can tell, they behave exactly as they should behave loading the assembly version they were built with.  For this test I have a Workflow Service that uses an activity from ActivityLibrary1 and we will run through a similar set of scenarios deploying a Workflow Service (.xamlx) to a web site hosted...
