My WEB site does not work with IE 11

I am developing a WEB site using VS 2010 with SQL Server 2008 R2 and have discovered that it does not work with IE Version 11.  It works with Versions 9and 10 along with Google Chrome, Safari, and Mozilla FireFox.  I've had problems with other WEB sites while attempting to use IE 11.  How can I modify my site to work with IE 11 or is this a Microsoft problem?  Thank you for any information you choose to provide.......................................Phil Hoop
