WCF and Idealblade

Hi,

I created a WCF service, in this service I use idealblade to retrieve the data and send the entities to the client.

I have a class, this class have a constructor and in this constructor I create an instance of my entityManager (this is inside a private variable of the class).

After that the other methods use this private variable to do my queries.

The WCF service is by session so when the session is closed I do a disconnect to my private variable and I put it null.

So I open my client first time I retrieve data from a table it works without any problem.

I close my client, I open it again I do the same call and I got an error than I cannot run the query in this thread because it's use by another thread .....

I don't understand why ?

So I remove the private variable and create a variable inside each methods that do a call to the database in the WCF service and I don't have this error anymore.

But is not really a good pratice, I want to have a private variable inside the class and I was expecting no problem of threading because the client is closed etc...

Regards
