A private assembly is an assembly that is deployed with an application and is available only for that application. That is, other applications do not share the private assembly. Private assemblies are installed in a folder of the application's directory structure. Typically, this is the folder containing the application's executable file.
For most .NET Framework applications, you keep the assemblies that make up an application in the application's directory, in a subdirectory of the application's directory. You can override where the CLR looks for an assembly by using the <codeBase> element in a configuration file.
