Assembly registration tool (Regasm.exe)
The Assembly registration tool reads the metadata in the Assembly and adds the required items to the Registry. The registry allows COM client programs to create. NET Framework classes transparently. Once the class is registered, any COM Client program can use it, as if the class is a COM class. Class is registered only once when the program is installed. Class instances in the Assembly cannot be created from COM until they are actually registered.
NET Service Installation Tool (Regsvcs.exe)
The. NET Service Installation Tool performs the following operations:
- Load and register the assembly.
- Generate and register the Type Library and install it in the specified COM + 1.0 application.
- Configure the service to be added to the class programmatically.
