Omaha COM interface

Omaha's COM interface described in file omaha\goopdate\omaha3_idl.idl.
Also after build Omaha client you can find it at:
omaha\scoons-out\opt-win\staging\idls
or
omaha\scoons-out\dbg-win\staging\idls

1. You need to convert type library omaha3_idl.tlb to assembly.
   • Launch "Developer Command Prompt for VS2015".
   • Locate omaha\scoons-out\opt-win\staging\idls\omaha3_idl.idl
     or
     omaha\scoons-out\dbg-win\staging\idls\omaha3_idl.idl.
   • Call tlbimp omaha3_idl.idl. This makes GoogleUpdate3Lib.dll.
2. You need to add reference to GoogleUpdate3Lib.dll in your .Net application.
   • Call "Add reference..." in VS2015 for your application project. Browse and select GoogleUpdate3Lib.dll.
3. You need to add using directive in your source code.
   • Before you can use the COM interfaces and classes you need to add uses directive in your source code.
