Registration-free COM interop is a Microsoft technology that activates COM components without using the Windows registry to store COM registration information. Instead of registering a COM component on a computer during deployment, you create Win32-style manifest files at design time that contain information about binding and activation. These manifest files, rather than registry keys, direct the activation of a COM object.

Using registration-free activation for your assemblies instead of registering them during deployment offers two advantages:

• You can control which DLL version is activated when more than one version is installed on a computer.
• End users can use XCOPY or FTP to copy your application to an appropriate directory on their computer. The application can then be run from that directory.
