Could not load file or assembly NHibernate error

[Catalin]

Hi,

I am trying to switch from NH 3.1GA to NH 3.3CR1, once I have substituted NHibernate.dll file with the new version, I am receiving the following error:

Could not load file or assembly 'NHibernate, Version=3.1.0.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

The environment I am working in is ASP.net 4.0, with some other libraries build on the top of NHibernate: NHibernate Burrows, FluentNHibernate, NHibernate Search, NHibernate Validator.

Should I recompile these libraries as well, with the NHibernate 3.3.0CR1 ?

I have googled around to find a solution, and I have found various hints (ex: deleting the temporarary internet folders, the bindingRedirect tag in the web.config file), but none of them succeeded to solve my problem.

What is the correct solution to this problem ?

Thank you,

C.

In principle yes, unless those projects themselves make builds
available. That is the unfortunate side effect. The bindingRedirect
should work though, except when actual incompatibilities occur.
