Install NHibernate 3.2 with NuGet

Question

I'm new to NHibernate and have been trying to get up and running with it, Fluent NHibernate and NHProf using NuGet. After reading this article (http://gurustop.net/blog/2011/03/13/nhibernate-3-1-0-on-nuget-important-details) it seems that v3.1 shouldn't be directly installed, however, there appears no such warning for v3.2.

After successfully installing NHibernate 3.2 and NHProf using NuGet, I'm unable to install Fluent NHibernate as it says it's "Already referencing a newer version of NHibernate".

Also, when I run my app I get the following error "Could not load file or assembly 'NHibernate.ByteCode.Castle' or one of its dependencies". The following link (Could not load file or assembly in NHibernate) suggests installing a number of additional assemblies, which is what I was hoping to avoid by using NuGet in the first place.

At this point would it just be easier to follow the steps on NHForge to get things up and running as the packages on NuGet don't appear to be compatible?

Answer 1

NHibernate 3.2 comes with its own proxy factory. If you're using a config file, you just need to remove the proxyfactory configuration property.

I believe the version of Fluent NHibernate that you're using defaults to use NHibernate.ByteCode.Castle. In that case, you would need to override that setting with the built in NHibernate 3.2 proxy factory:

.ProxyFactoryFactory("NHibernate.Bytecode.DefaultProxyFactoryFactory, NHibernate") 

Answer 2

Each version of Fluent NHibernate uses an exact version of NHibernate (included in the Fluent NHibernate package) You should remove the NHibernate package and add only Fluent NHibernate

Answer 3

If you use the Nuget Package Manager Console instead of the GUI to get the package (Install-Package FluentNHibernate) you will get version 1.3.0.717 which is compatible with NHibernate 3.2

I tried and is working fine for me. I answered this already on this link: which version of fluent nhibernate is compatible with nhibernate 3.2

Answer 4

I'm using this consctruction in config file to make FluentNhibernate work with NHibernate 3.2

 <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="NHibernate" publicKeyToken="aa95f207798dfdb4" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-3.2.0.1001" newVersion="3.2.0.1001" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

NHibernate 3.2 comes with its own mapping configuration (Conform). FluentNHibernate only works with NHibernate 3.1 as a result of this, you can't use 3.2 (I had the same problem). So you'll have to manually download 3.1 and reference that unless NuGet allows you to use 3.1 directly.

Your other option is to remove all references to 3.2 and then install FluentNHibernate from NuGet, then the dependency resolver will kick in and automatically include NHibernate 3.1 for you.
