Release 10.1A: OpenEdge Development:
.NET Open Clients

> ## Session-free threading model

> Open Client applications that use the session-free model are presumed to employ a threading model such that each request executes on a separate thread. This becomes particularly important in the following areas:

> - When the application constrains the size of the connection pool, requests can become blocked if connections are unavailable. This is accomplished by the Open Client Runtime blocking the thread on which the request is run.

> - Certain request-specific methods must be executed on the same thread on which the request was run. See the "Common methods" section for more details.
