I have a solution comprising of 5 projects. the bulk of the business logic is sitting in a class library project - producing 1 dll.

When I build the solution its now failing, because this dll is not effectively being updated in a web site project in the same solution.

I ran a test... and changed the file version of the project properties for the class library to 1.0.0.1. So effectively v1.0.0.0 does not exist.

However each time I build, for some reason - the old DLL is getting added to the bin directory of the web site... while the new v1.0.0.1 dll is outputted correctly to the projects bin/debug directory.

I've tried deleting and recreating references. No joy... not sure what else to do, any suggestions would be most welcome...

Update: To simplify the problem

When I build the class library output, output is - 1 project build successfully.

It creates good version of DLL in project bin/debug.... It creates old version of DLL in website project.......

Any suggestions on where to look from here?
