# Registration-free COM interop

By Roy Osherove July 28, 2003 In [.Net Quotations](https://osherove.com/blog/category/net-quotations)

**Historical article** · Originally published July 28, 2003; technical details may be outdated.

_[Registration-free COM interop](http://www.123aspx.com/redir.aspx?res=30741) activates a component without using the Windows registry to store assembly information. Instead of registering a 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 an object.
