.NET 3.5 Web应用程序-移植到64位-潜在问题

Question

I have an existing ASP.net 3.5 web application. This is tested and working in a 32 bit environment. There is a plan to move this application to a 64 bit environment.

As a first step, the plan is to compile the entire application in "Any CPU" Is anyone aware of any plan / checklists that can be used in porting from 32-bit to 64-bit?

As the hardware is still in procurement, it will be a while before the actual system testing will start and hence we want to try and minimize the amount of issues that come up during the actual system testing.

Answer 1

Firstly: get hold of a cheap 64 bit laptop or desktop, and start testing on that. You don't need a full meaty server to start doing smoke tests.

Secondly: do you perform any native interop (eg using a COM component)? That's where I'd expect potential errors.

Answer 2

Check out this MSDN article on migrating from 32bit to 64bit with .Net. Contains issues, things to watch out for, and what the framework promises. (I never trust any framework's guarantee..it's always a strongly worded promise in the best of times :-)
