Importance of setting cpu architecture type in Visual Studio C# [duplicate]

Question

Is it really important to specify architecture type if I'm making a simple Windows program that utilizes HttpWebRequests, or is it ok to leave it as "Any CPU"?

Answer 1

Any CPU means the .NET framework just-in-time (JIT) compiler will compile your intermediate language (IL) to either x86 or x64 at runtime on the client machine, based on its architecture. If you are not linking to any DLLs that are specifically either x86 or x64, then you are safe to (and should) leave the configuration as Any CPU.
