Web Development Best Practice

[Rui]

Hello I was looking at your samples in the SDK.
In bestpracticewebdevelopmenttwo you have:

public class ContextFactory
    {
        public static NorthwindContext GetContextPerRequest()
        {
            HttpContext httpContext = HttpContext.Current;
            if (httpContext == null)
            {
                return new NorthwindContext();
            }
            else
            {
                int contextId = Thread.CurrentContext.ContextID;
                int hashCode = httpContext.GetHashCode();
                string key = string.Concat(hashCode, contextId);

                NorthwindContext context = httpContext.Items[key] as NorthwindContext;
                if (context == null)
                {
                    context = new NorthwindContext();
                    httpContext.Items[key] = context;
                }

                return context;
            }
        }
    }

Using this method how will the NorthwindContext be disposed?

Hello Rui,

You have probably seen the old version of this example, available with Q3 2011 of OpenAccess SDK.

In the latest release of the SDK (available on our web site for free) you can check the refactored and renamed sample now called "Managing OpenAccess Context" in the ASP.NET category. There, you will find the following way of disposing the OpenAccessContext in case you have chosen to store it in the HttpContext:

public class Global : HttpApplication
{
    protected void Application_EndRequest(object sender, EventArgs e)
    {
        NorthwindContext context = ContextFactory.GetContextPerRequest();
        if (context != null)
        {
            context.Dispose();
        }
    }
}

I hope that helps. Let me know if you have any further questions. 

All the best,
Ivailo
