Partial classes and partial methods are two programming language features of .NET programming languages that make it possible for developers to extend and enhance auto-generated code. In a nutshell, a partial classes allow for a single classs members to be divided among multiple source code files.

At compile-time these multiple files get combined into a single class as if the classs members had all been specified in a single file. Partial methods are methods defined in a partial class that are (optionally) divided across two files. With partial methods one file contains the method signature - the method name, its return type, and its input parameters - while the body is (optionally) defined in a separate file. If the partial methods body is not defined then the compiler automatically removes the partial method signature and all calls to the method at compile-time…
