c#

I have a ClickOnce program that associates with a given extension and that works fine if the file is located on the file system. My problem comes in when this file is downloaded from a website. I have a web handler that prompts the user to Click to download the file. Upon clicking the link the user is presenter with an Open or Save Dialog. If the user chooses Open the program will not launch. If the user saves the file to their hard drive and then clicks the file the association will work.

Any advice on getting the association to work on the prompt when the user clicks Open or is a Save required?

-Edit : Tested this on both IE8 and Chrome with same result.

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
