• Software Development for Windows Vista How can a new activity class be derived from a parent class that has a mandatory property?

  I'm trying to use a new Workflow Activity Library project containing an activity class AChild that derives from class AParent which has a manadatory property. Because AParent has a manadatory property, my library project for class AChild won't compile (because AParent's validation rules complain that the mandatory property isn't set).

  After I installed SqlServer2K5_BOL.msi, Microsoft SQL Server Management Studio Express CTP does not launch any more. How can I use both SSMSEE and BOL I would be very skeptical when downloading either of those files. MS download servers currently have a fairly serious (in my opinion) problem with syncronizing their mirroring. It seems to lead to some mirrors providing outdated files - it's meant to be trans ...Show All
