I have a solution containing multiple projects.  I added a refence to each object in the main project but the bin folder never updates with the new dll's. I can see the new dll's in the debug/obj path and the properties for the references are set correctly including copy local = true. Does anyone know how to fix this?

The other projects are probably not being built when the first one is.  Try this, highlight your solution, click Build (main menu bar)>Configuration Manager.  When you build one you want to build another right?  If so, check the boxes.

Then check the project dependancies.  Click Project>Project Dependancies and double check they are set right.  You can also click on the Build Order sheet to see if it builds them correctly.  If all else fails, move the dlls to another folder, and click Rebuild, this should recreate them for you.

 Thanks for the reply. All of things you suggested are configured correctly. It rebuilds the dlls and they are refreshed in the obj/debug folder. The problem is they are never copied to any of the bin folders. This seems kind of weird.

Hi,

Firstly, please make sure that the project is built and the dependence relationship is right.

Did we get any warning in Visual Studio Output window? Please make sure the old dll is not using.

You also can use post-build event to copy the dll (http://geekswithblogs.net/dchestnutt/archive/2006/05/30/80113.aspx).

I look forward to receiving your test results.
