Opening and closing connection to CRM from web application

Posted on by Genato 56

Ok as i mention am working on ASP.NET MVC5 application and am having hard time finding what is the best practice to create, keep open and to close connection to Dynamics CRM 365?

I found some many posts and blogs but everyone pulling on his side of the road.

Some say it's better for every request to open new connection in using statement so it could be closed right away (that's sounds good but it's a possible that requests will be slow because on every request it needs to open new connection to CRM). 
Some say it' better to make singleton object on application scope, keep it open during application lifetime and reuse it on every request.

Normally i would use OrganizationServiceProxy in some simple console app but in this case am not sure should i use OrganizationServiceProxy or CrmServiceClient or something else?

If anyone have or had some similar problem, any hint would be great.

Thank you :)

    No,

    You can use conn.Dispose() when you are done with the connection.

    This is basically the same for every class that implements the IDisposable Interface.

    If you use the Crm Service Client, you can set it to use the IDisposable Interface:

    using (CrmServiceClient conn = new CrmServiceClient(creds, authType, internalUrl, "443", orgName, true, true, null))

    {

    }

    The IOrganizationService does not implement the IDisposable Interface.

    Hope this helps.
