This is something I missed most in Visual Studio 2012. When we try to change the code when debugging 64-bit applications in Visual Studio 2012, we are thrown with this message.
|Changes to 64-bit applications are not allowed in Visual Studio editions prior to Visual Studio 2013|
But not anymore. Visual Studio 2013 Preview gives us the ability to modify the code while debugging 64-bit applications. Isn't it just great. There were 2,613 votes for the request asking this features to be included in next Visual Studio releases in Visual Studio UserVoice Site.
