I upgraded from version 4.4.0 to 4.4.1, I am facing a problem when running the app"

Assembly 'bcps.model, Version=, Culture=neutral, PublicKeyToken=null' is not processed by PostSharp. See section 2 of Manual for details

I need an urgent resolution to this problem.

PostSharp is not installed and not enabled.

Hello Akhtar,

Could you check whether your project references the updated Xtensive.* assemblies? I mean it should reference assemblies with version instead of as it was before the upgrade.

Having that done try rebuilding the solution.


The investigation revealed that csproj-files contained line


After the line is removed, all works fine.

I completely uninstalled, reinstalled the new version and upgraded the solution. Surprisingly, the references were not copied (which is another issue) except Xtensive.Practices.Web.

So I manually added all the missing references to

Xtensive.Aspects Xtensive.Core Xtensive.Orm Xtensive.Practices.Web Xtensive.Testing (it was automatically added)

All these assemblies are version (I have double-checked them)

I set the option in the Web.config to Upgrade='Recreate' and targeted to a new blank database, still not working.

Actually, if you are not using Aspects, do not install PostSharp!

Your tips were very helpful. Thanks very much for helping us troubleshoot and fix the problem in such a short time frame.

We appreciate the DO4 folks for their proactive and sincere support (always real time!).
