I am updating a text box on an xmal page. I was getting an issue "UnauthorizedAccessException when trying to update the UI.

A bit of searching and I found the solution was as follows:

 
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
this.ResponseText.Text = "Using HttpWebRequest: " + resultString;
}
);

Its cool that my issue is resolved, but i need to understand whts going on above. I dont understand the syntax "() >={//code} . Can anyone break this down, for an absolute novice?

It is a "Lambda" expresion/function, also known as an anonymous function. Search the articles in this web site for lambda; there are more than ten articles. Also search for anonymous but you will get many results that are not about anonymous functions; you just need to overlook articles that are not relevant. You can find ample explanations in the articles in this web site.
