    But, what does 64-bit SL mean to the end-user? Is it that we can load bigger XAPs or is it that the XAP gets loaded faster or is it that the code runs faster or what?


    And here is the link to the security whitepaper:

    For Silverlight, the main benefit of 64-bit is being able to run inside 64-bit browsers and other 64-bit hosts such as the Windows Sidebar.  Note that you can have a 64-bit OS and still run 32-bit apps, and in fact 32-bit IE is the default on 64-bit Windows 7, but we think 64-bit browsers will become increasingly popular.
    64bit also allows you to take advantage of more memory, so you can have a process that's greater than 2GB.

    Thanks Nick; Ever since the news of SL5 came out, I've heard many [sort of] end users, ask what would be the benefit of running the IE64 and SL5? The memory was one of the things that I had brought up, but wasn't sure with app would run faster and/or load time would also become faster too.

    Infact once I saw WinForm 64-bit version that ran slower than a 32-bit version and the developer told me, there is a lot more prcessing time involved with managing much larger memory that they were allocating and using.
