Can a cloud-enabled Windows app support itself financially?

Standard

Which Windows and/or Windows Phone app business model suits an app with a Microsoft Azure backend?

It would seem that an app purchased from the Windows Store for, let’s say, $1.49 (which is one-time revenue) would quickly be consumed by the continuous (variable) cost of the cloud services it interacts with. What is viable? Ads? In-app credits that get consumed and replenished based on backend usage?

SharePoint 2010 Advanced Developer and IT Professional Training

Standard

Earlier this year I was fortunate to take a week off and virtually attend the SharePoint 2010 Ignite Developer training. This was an intense deep dive into the new capabilities of SharePoint 2010 and included a number of virtual labs where we got to practice new learnings on actual servers.

After digging around my email for links to these training materials for download I was pleased to find that this training has now been made public, including many of the virtual lab exercises! See links below and enjoy.

HttpWebRequest, HttpWebResponse, and the WebException

Standard

Calling the GetResponse() method on the HttpWebRequest class yields some interesting results. It determines that a status code of anything else but 200 (OK) is an exceptional case and throws a WebException exception.

The following code demonstrates how to return the status code even if the URL in the request is not OK.

HttpStatusCode httpStatusCode;
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://invalidsitename.net/");
try
{
    using (HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse())
    {
        httpStatusCode = httpWebResponse.StatusCode; //OK
    }
}
catch (WebException webException)
{
    if (webException.Response != null)
    {
        HttpWebResponse httpWebExceptionResponse = (HttpWebResponse)webException.Response;
        httpStatusCode = httpWebExceptionResponse.StatusCode; //Something other than OK
    }
    else
    {
        throw webException; //Invalid host name
    }
}
return httpStatusCode;
