I'm trying to use linq to NHibernate (with Fluent NHibernate) but I have problems with linq query. Everytime I try to execute it I get this message :
"Method 'get_IsReadOnlyInitialized' in type 'NHibernate.Linq.Util.DetachedCriteriaAdapter' from assembly 'NHibernate.Linq, Version=1.1.0.1001, Culture=neutral, PublicKeyToken=null' does not have an implementation."
Does anybody know how to fix this problem? I tried with solution form this page with model context but it didn't help.
This is the code:
using(var session = NHibernateHelper.OpenSession()) { var informations = (from i in session<Information>() where i.Text=="some text" select i).ToList(); } Everything is fine if I don't use the where part but if I use it I get this error. I think that the problem is in NHibernate.Linq.dll

"As long as LINQ to SQL lives under Entity Framework, it's dead.
More importantly: when it comes to querying databases, LINQ is in most cases a significantly more productive querying language than SQL. Compared to SQL, LINQ is simpler, tidier, and higher-level.
LINQ syntax is typically less efficient than a foreach loop. It's good to be aware of any performance tradeoff that might occur when you use LINQ to improve the readability of your code. And if you'd like to measure the performance difference, you can use a tool like BenchmarkDotNet to do so.
You should not use NHibernate.Linq.dll with NHibernate 3.0! NHibernate 3.0 has Linq included (a by far better version than the old extension dll), you just need to add using NHibernate.Linq; and use session.Query<T>() instead of session.Linq<T>().
