 To load the correct assembly, it's recommended to call the `Load` method by passing the long form of the assembly name. The long form of an assembly name consists of its simple name (such as "System" for the System.dll assembly) along with its version, culture, public key token, and optionally its processor architecture. It corresponds to the assembly's <xref:System.Reflection.Assembly.FullName%2A> property. The following example illustrates the use of a long name to load the System.dll assembly for .NET Framework 4:
