Oracle databases can now be integrated with your visual studio solution. Quest Software made a product: TOAD Extension for Visual Studio that enables Visual Studio 2010 Database Development Tools (aka DBPro, VSTS4DBP or datadude) to create database projects based on Oracle database. There is a freeware version of the extension which has limited functionalities compared to the commercial version, but still, you are able to create db projects with it.
I tested this extension and it works great. I’ll surely blog over the next few weeks about my “user experience” with this product.
