Visual Studio Project DLL not updating in web site project (same solution)

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开发者_StackOverflow 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?

Here is a screen cast of the issue http://www.screencast.com/t/Mjc2NjM1ZD

Have you made a project reference or a direct file reference? It should be a project reference. If it already is, then try the following: run an iisreset and the open \windows\microsoft.net\framework[64*]\Version**\Temporary ASP.NET files\ and delete everything within. Now rebuild and see if you have any luck.

1) if you're on a 64 bit machine 2) the version corresponding to the .net version of your apppool (v2 or v4)

Hope it helps.

Have you got Copy Local set to true on the reference? Right click on the reference, go Properties, and it is an option there.

I had this problem recently and found I needed to manually delete the reference locally

• Navigating to the \_bin_deployableAssemblies folder and delete the references here

• Go to Visual Studios and remove the reference from the reference section

• Clean and Rebuild the project(s)

When you check the _bin_deployableAssemblies you should now have new version dll's.
