I use linux in my laptop. and I don't like to have a windows on it (any way). My collage website designed with .net and aspx. It has greate features and the site application is something like a desktop application in a browser (greate job). Somehow it's nothing but shit: The website just work with IE in windows OS (I think. May be it use windows librarys, if it's possible for a website).
I tried a lot to open the site with linux(installing ie with wine) but there is no success!
Is there any way to open the site in linux? Or there is no IE/Window specific site's and I don't installed IE correctly?

The Google Chrome browser has some add-in extensions that let you run a tab in IE mode. Some only run on Windows, but others don't care. You might want to check them out.
