1. do I need to create a html file to call this xbap from browser? If I need to, can you please give me the sample tags how to call?
2. I tried to call xbap it looked like it was executing but did not, it seems like certificates or permissions are the issue, if I want to give certificate or permissions, how can I do it on the Virtual directory? I am using IIS 7
3. Do I need to install MIME types on IIS to exec my xbap file? Reason is I got a script from msdn which installs it but it was giving me error, if I need to have them installed, is there any better and guaranteed approach to do the same on IIS 7.
