We can dynamically reference an assembly by providing only 
partial information, such as specifying only the assembly 
name. When you specify a partial assembly reference, the 
runtime looks for the assembly only in the application 
directory.

We can make partial references to an assembly in your code 
one of the following ways:

1) Use a method such as System.Reflection.Assembly.Load and 
specify only a partial reference. The runtime checks for 
the assembly in the application directory.

method and specify only a partial reference. The runtime 
checks for the assembly in the application directory and in 
the global assembly cache.

A full assembly reference includes the assembly's text 
name, version, culture, and public key token assembly has a 
A full assembly reference is required if you reference any 
assembly that is part of the common language runtime or any 
assembly located in the global assembly cache. You can also 
dynamically reference an assembly by providing only partial 
information, such as specifying only the assembly name.
