Please see my comments to the question.
dean rezo asked:Can you give me more details about architectures: x86-64 and Itanium (IE64)?
Sure. Please see:
When you build a .NET project, you have four options for the "Platform" option ("Platform" means instruction-set architecture
in Visual Studio and MSBuild jargon): one 32-bit architecture, two 64-bit architectures, plus "AnyCPU". "Any CPU" is possible because CIL code of an assembly is generally abstracted from the instruction-set architectures, as .NET is based on JIT compilation. Please see:
In a .NET assembly, using a specific instruction-set architecture generally makes no sense. However, it is important when some native code is used, or the assembly is used by some native (unmanaged) code. Even in this case, most of the assemblies involved in some process/application should be compiled (marked) as "Any CPU".
