Is my VB.Net/SQL db application compatible with Vista 64-bit?

I have a VB.Net application using .Net Framework 2.0 and SQL Express for the database.
Will this work with 64-bit edition of Windows Vista?

    Accepted Solution

    It depends. There are so many variables.

    SQL Express is not 64-bit.
    It should work on a 64-bit Vista using Windows on Windows (WOW), if you have SQL Express with SP2.

    There have been problems with the SQL Server Management Studio Express (again, you must have SP2 or later).

    I'm not a developer, so I have no experience with the VB.Net side - but this link may interest you.

    Are you using the 64-bit version of the .NET Framework?

    Generally speaking, everything from the 32bit version of VB.Net will work  on Vista 64.   The default for most .Net applications is "Any CPU", which means that it will try to run as a 64 bit application on Vista 64 automagically.

    There are a few "gotchas" that you might run accross with a 64bit app... but they generally occur when doing low-level things like P/Invoke and IntPtr conversion.
