-refonly (Visual Basic)

The -refonly option indicates that the primary output of the compilation should be a reference assembly instead of an implementation assembly. The -refonly parameter silently disables outputting PDBs, as reference assemblies cannot be executed.

Every compiler option is available in two forms: -option and /option. The documentation only shows the -option form.

Syntax

Console

-refonly

Remarks

Visual Basic supports the -refonly switch starting with version 15.3.

Reference assemblies are a special type of assembly that contain only the minimum amount of metadata required to represent the library's public API surface. They include declarations for all members that are significant when referencing an assembly in build tools, but exclude all member implementations and declarations of private members that have no observable impact on their API contract. For more information, see Reference assemblies in .NET Guide.

The -refonly and -refout options are mutually exclusive.
