Global Assembly Cache

Each computer where the common language runtime is installed has a machine-wide code cache called the global assembly cache. The global assembly cache stores assemblies specifically designated to be shared by several applications on the computer.

You should share assemblies by installing them into the global assembly cache only when you need to. As a general guideline keep assembly dependencies private and locate assemblies in the application directory unless sharing an assembly is explicitly required. In addition it is not necessary to install assemblies into the global assembly cache to make them accessible to COM interop or unmanaged code.

In a strongly typed language all variables have a type that must be declared. In addition the compiler verifies the type consistency of expressions (and expressions are always of a type defined by the C# language or are user-defined types).

RE: What is GAC? What are Strong and Weak Types?

As a practical matter working in a strongly typed language means that you need to need to be very clear about the type of the information that will be stored in a variable. Strong typing enforces programming discipline and clarity about the contents of variables. It also prevents possible program errors that can occur in weakly typed environments when the compiler finds the wrong kind of value in a type. Another way of thinking of this is that weak typing allows a programmer to be lazy in a possibly dubious type conversion the compiler guesses what the programmer most likely meant (which can occasionally introduce errors).

A machine-wide code cache that stores assemblies specifically installed to be shared by many applications on the computer. Applications deployed in the global assembly cache must have a strong name.
