Azure error handling

This isn't so much about error handling in azure as it is error handling in asp.net.  Ok the title kinda lied.. :) 

Adding error handling in asp.net is easy:

1. Create an error page in your application (eg error/Error.aspx). 


2. In the <customErrors/> config, set the defaultRedirect="error/Error.aspx" and voila!


3. You have a couple of opportunities to handle the error (when it happens, in the page, or in the application):
   
   
   
   • In the page: public void Page_Error(object sender, EventArgs e)
   
   
   • In the application (Global.asax: protected void Application_Error(object sender, EventArgs e)
   
   
   
   


4. Then you can access the actual exception via Server.GetLastError().GetBaseException();

So at work our exceptions get mailed.  Since azure currently doesn't have mail servers, we opted to use SendGrid which seemed quite ok.
