/FU (Name Forced #using File)
A compiler option that you can use as an alternative to passing a file name to #using Directive in source code.
Syntax
/FU file
Arguments
file
Specifies the metadata file to reference in this compilation.
Remarks
The /FU switch takes just one file name. To specify multiple files, use /FU with each one.
If you are using C++/CLI and are referencing metadata to use the Friend Assemblies feature, you can't use /FU. You must reference the metadata in code by using #using
—together with the [as friend]
attribute. Friend assemblies are not supported in Visual C++ component extensions C++/CX.
For information about how to create an assembly or module for the common language runtime (CLR), see /clr (Common Language Runtime Compilation). For information about how to build in C++/CX, see Building apps and libraries.
To set this compiler option in the Visual Studio development environment

Select the Configuration Properties > C/C++ > Advanced property page.
