Hi,

What is the context in which you are calling for the data.

Your answer has already been supplied to you.

You are working in STA app and should do this work asynchronously.

Large data blocks = long waiting time.

Dear NhibernateUsers, 

 

I am also getting same errors.Could anyone please help on this.For large data,  
 query.List();   taking alot of time and  finally giving  error  like " The CLR 
has been unable to transition from COM context 0xd89ba8 to COM context 0xd89af0 
for 60 seconds  "  but for less data It's working fine.

 

Regards,

Raju Kushwaha

likely either doing a non pumping wait or processing a very long running 
operation without pumping Windows messages. This situation generally has a 
negative performance impact and may even lead to the application becoming non 
responsive or memory usage accumulating continually over time. To avoid this 
problem, all single threaded apartment (STA) threads should use pumping wait 
primitives (such as CoWaitForMultipleHandles) and routinely pump messages 
during long running operations.'

 

 

I am getting above error at below line 
System.Collections.IList list = query.List();

 

and here IQuery is interface of NHibernate.
