New Post: Performance issues

I've found that a DbContext is quite a bit more expensive to create than an NHibernate session. Just like you reuse your NHibernate session factory, so can you reuse a DbContext.

However, DbContext isn't threadsafe so when I have a class that is going to be called from many threads I manage my context with a thread local variable like this:

    private readonly ThreadLocal<DataContext> _contextProvider = new ThreadLocal<DataContext>(() => new DataContext());

Then in the method I just use _contextProvider.Value as I would a new context.
