"Application Scenario"

Assembly A accesses the members of the class that are defined by Assembly b for the Internal access type.

"How to use"

When building Assembly B , introduce System.Runtime.CompilerServicesto add InternalsVisibleTo attribute

Example

Assembly b--

using System; using System.Runtime.CompilerServices; // for InternalsVisibleTo Properties // the internal types in the current assembly can be set by the following assemblies // any code access (no matter what version or language culture) [Assembly:internalsvisibleto (" Assembly A's name, publickey=1234 ... " )]internalsealedclass someinternaltype{...}

Assembly a--

using System; Internal Sealed class Foo {  privatestatic  Object SomeMethod () {    //  This assembly a can access the internal type in another assembly    ,// as if it were a public type    new  Someinternaltype ();     return sit;  }}

Note

Do not specify a version number when adding InternalsVisibleTo attribute, language culture and processor architecture
