Namespace aliasing and extension methods

One of the interesting thing that i learned today is, namespace aliasing can break extension methods declared in the name space.

To safeguard against this situation add the same namespace again without alias. For example

using alias=X.Y.Z;

should be changed to

using alias=X.Y.Z;

using X.Y.Z

and everything works,

Happy Coding,

IIS Url Rewrite and HTTP POST data

If you play around with IIS Url Rewriting rules and try to do redirects on an HTTP POST you loose your POST data. To make sure you get the post data you have to set the `redirectType` to `Temporary` within your rules. So the action configuration looks like this <action redirectType=" Temporary " type="Redirect" url="http://{HTTP_HOST}{REQUEST_URI}"> </action> You may think what scenario warrant a POST request redirect. We faced one such scenario while doing SSO with a federated Identity Provider (IP) such as Google, Azure AD. In federated authentication scenario once the user is authenticated by the IP, it redirects back to your site with claim tokens in a POST request over secure channel (https). In our case we wanted to redirect to user back http after receiving the request. But any redirects were causing loss of token. By doing a 307 (Temporary) redirect we were able to preserve the post data.

Caching Images downloaded from web on Windows Phone Isolated storage

I was helping on a Windows Phone application where the requirement was to cache the images the phone downloads on the isolated storage for offline viewing. I wanted a solution which was simple and as transparent as possible. While researching I found someone wrote a Silverlight converter for loading images from isolated storage. Taking that as a base I created a converted which can Load image from web (http + https), and persist it to isolated storage. In case of network connectivity issues can load the same image from isolated storage. It does that by mapping the http url to a isolated storage location. In case the network is down and the image is neither there in cache, loads a default image, passed as parameter to converter. Here is the gist for the implementation. To use the converter Import the name space. Declare the converter as resource. Set the Image Source Property to use this converter like this
