The lack of proper integration in VS2008. The need to buy , learn expression blend to do the same job we now do with just the VS tools. Everyone here knows how to use and code winforms. The data binding and events. Having to switch to another tool with no real benefit is costly in terms of lost man hours , train and, additional development tools.

At the end of the day we will have the same style forms we had before we started. A form to enter data with a save button isn’t going to change a whole lot. We will have just spent hours and funds.
