I've got 2 problems with express-c (with no anual subscription):
- there are no fix packs included.
- some features are missing, so can develop an application that uses them. In my particular case that is SQL replication.
In the information center there is mentioned "Developers license" here:

but I fail to find any info how/where to get it.
