Get ready for Microsoft certification exam for Azure developers later this year or early next year. It's been 10 months now that we are working with Azure. I guess when the exam get released I am ready to take it.

I stumbled upon Scott Hanselman's post "What great .NET developers ought to know". There are things that I am already familiar with and I've experienced working in actual projects but I still don't know their exact definitions - like a by-the-book definitions. Some are really tough ones. 

Ayende post his own answers with Scott's questions here. 

You get an error Method not found: 'Boolean System.IdentityModel.Selectors.SecurityTokenRequirement.get_IsOptionalToken()' when you try to access a WCF with clientCredentialType is set to either of the choices except None. When set to None you can successfully connect to WCF service.

The problem has something to do with recent update for System.ServiceModel.dll and System.IdentityModel.dll.

The fix is to install the Microsoft security patch KB976394 - WCF: Make OutgoingSupportingToken public.  

As part of June 2010 update for Windows Azure Tools, Azure Storage can now be browsed through VSTS Server Explorer.
