Eran,
I'd be happy to help find custom step type definitions that would aid you in your development. However,, a little more information would help me to identify an example that would best suit your needs.
Are you looking for a custom step type which always calls into a C# or VB .NET assembly? Do you want the step type to always call the same code each time? Is there any extra functionality you are looking to include in the step type definition (such as extra information in the Result Container of the step)?
I look forward to your response. Have a great day!
