You are developing an assembly that will be used by multiple applications. You need to install the assembly in
the Global Assembly Cache (GAC). Which two actions can you perform to achieve this goal? (Each correct
answer presents a complete solution. Choose two.)

A.
Use the Assembly Registration tool (regasm.exe) to register the assembly and to copy the assembly to the
GAC.

B.
Use the Strong Name tool (sn.exe) to copy the assembly into the GAC.

C.
Use Microsoft Register Server (regsvr32.exe) to add the assembly to the GAC.

D.
Use the Global Assembly Cache tool (gacutil.exe) to add the assembly to the GAC.

E.
Use Windows Installer 2.0 to add the assembly to the GAC.

Explanation:
There are two ways to deploy an assembly into the global assembly cache:
Use an installer designed to work with the global assembly cache. This is the preferred option for installing
assemblies into the global assembly cache.
Use a developer tool called the Global Assembly Cache tool (Gacutil.exe), provided by the Windows
Software Development Kit (SDK).
Note:
In deployment scenarios, use Windows Installer 2.0 to install assemblies into the global assembly cache. Use
the Global Assembly Cache tool only in development scenarios, because it does not provide assembly
reference counting and other features provided when using the Windows Installer.
