.NET components

Hi,

I'm struggling to find .NET equivalents for current used COM Automations. Any help or hint in the right direction would be very helpful. Currently open .NET equivalents for COM components are:
- Microsoft Scripting Runtime
- Microsoft Shell Controls and Automation
- Microsoft Script Control 1.0
- Microsoft VBScript Regular Expressions 5.5
- Navision Contact Search 1.0

Thanks in advance.
