What is the difference between the 2 in terms of .net programming?

<div>
Programming wise there is no major difference. Memory wise, you consume double the memory.<br />
eg. size<br />
int = 32bits (32), 64bits (64)

<div class="content wysiwyg-content">
I have an application (Winforms and WPF) and a windows service (WCF) which runs on windows 7 x86 (32-bit). If the application is run on a 64-bit system, is it possible to run into some problems?<br />
<br />
If so, then what are the programming considerations to make sure that it works on both?

.NET Application Compatibility on 32-bit and 64-bit

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
