.NET Target Platform
The .NET Target Platform option specifies the target platform for the generated VLF.NET application.
The default value is AUTO which means that the runtime platform is determined by the operating system architecture. Setting the option to X86 will force the generated VLF-NET application to run in 32-bit.
Generally designers do not need to change this value unless their VLF.NET application has to specifically run as a 32-bit application.
An example of such a situation is when an application uses a 32-bit ActiveX control (such as Office Excel 2003 Web Component), it is necessary to force the generated VLF.NET application to run in 32-bit because 32-bit ActiveX cannot be hosted in 64-bit applications. It this case you would set .NET Target Platform to X86.
