Entry point not defined

Hi people.

Im using source code from a microsoft self paced book(70320) to create and consume a component (com+)

when I try to build the project I get the following message:

Program 'C:\EC70320\BankAccounts\obj\Debug\BankAccounts.exe' does not have an entry point defined

I've created the snk file using the Sn.exe tool

and here is the source code, im not sure where im going wrong
