Visual Studio 64-bit application Compilation

The platform under Visual Studio compilation option build contains x64, any CPU, and x86. X86 indicates that it can only run in a 32-bit environment, x64 indicates that it can only run in a 64-bit environment, and any CPU indicates that your Assembly can adapt to 32-bit or 64-bit environment changes, however, if your Assembly depends on an Assembly compiled with the x86 option, which of the following statements can only be used for compiling your Assembly, rather than any CPU compilation? If any CPU is used for compiling, the following error occurs during running:

Unhandled exception: system. badimageformatexception: cocould not load file or ASSE

Gram with an incorrect format.
File Name: 'sourcecode. hostclientapi, version = 4.0.0.0, culture = neutral, publicke
Ytoken = 16a2c5aaaa1b130d'

The reason is that if any CPU is used for compilation, the default running on 64-bit machines is 64-bit. Generally, 10 Assembly needs to call a 32 com library, as long as x86 compilation is used, the program is a 32-bit program that runs on the 64-bit system by running wow64. Therefore, if the Assembly needs to use the Win32 library, you must note that the default any CPU cannot be used in the compilation option.

If your Assembly has an Assembly compiled by calling VC ++, if Microsoft Visual C ++ 2005/2008/SP1 redistributable package (x86) update package is not installed, a similar error may occur:

The specific use of Microsoft Visual C ++ redistributable package versions 2008, SP1 depends on the version of Visual Studio used by your applications.

Microsoft Visual C ++ 2008 SP1 redistributable package (x86 ).

The above problem occurs in my summary of the problems I encountered when I was preparing to deploy the application on Windows Server 2008 R2 server core. It took nearly one day, we hope to help students who encounter similar problems in the future and save more time.
