NHibernate version: 1.0.2.0

Hi there

I'm currently developing a WinForms application using NHibernate and have about 250 mappings in total.

The problem is that BuildSessionFactory is taking 25+ seconds to run which is causing problems for our Windows based app.

I understand that there's a lot of information to process in the mapping files, but is there any way to reduce this startup time, ie caching the result of the process somewhere? Perhaps I should be looking to remove some complexity from my mapping files?

Any ideas would be appreciated.

Thanks for your help.

Try disabling the reflection optimizer (set Environment.UseReflectionOptimizer to false before creating the Configuration).

Excellent, that solved the problem!

I assume this may affect runtime speed in certain areas due to the optimization not having been processed, but I know I can't have it both ways ;-)

Thanks very much :-)

If you are using .NET 2.0, you should look at this forum thread. I think you can have your cake and eat it too!
