It became clear that we have a great agenda for developers at our TechDays. We really have sessions that talk to all aspects of developing a solution. The agenda mapped perfectly to the needs of the developers at that ISV.
Our preconference is great for our developers building solutions on Sharepoint. I said it before and I will say it again, there are not enough Sharepoint developers in the market! http://www.microsoft.com/belux/techdays/developers_preconf.aspx
The general days offers something for every developer: http://www.microsoft.com/belux/techdays/developers_conf.aspx
These are some of my favorites sessions on SCRUM, VSTS, Unit Testing, Authentication done right, Visual Basic SQL Server. See the full list at the other end of the link above!
