<P>I am new to Leadtools and fear that I am in the deep end of the pool.

It appears you were using the COM programming interface in version 14.5. If yes, then the old COM objects were not migrated to LEADTOOLS 16.x.
Since you're using .NET, there is no need for you to look for a COM interface. Instead, you can use the native .NET classes in your project.

However, the design of the .NET classes is different from that of the old COM objects, so you will need to re-write the parts of your program that use LEADTOOLS.

If you face any problem while migrating, check our .NET demos that install with the toolkit and feel free to contact us if you can't find the answer there.
