>it looks like I am about to get a job developing a new system to administer an Insurance Company's handling of Life Insurance. I am looking at using .Net for this system, but am unsure as to what specifics I should go with. I have used CSLA.NET before and liked it so will probably stick with that as my "business framework", SQL Server will be my data store (I might consider PostgreSQL or MySQL). The application does not need to be accessible over the internet, but I would like the possibility to be there. I am leaning towards using Silverlight (CSLA.Net for Silverlight), but I am unsure of the advantages/disadvantages of going this route. Maybe Silverlight is too young/new? Should I go with ASP.NET instead?

Stick to ASP.NET for a line of business application if you want it accessable over the internet. You have a mature framework, tools, controls, and development environment.
