.NET to .NET Core API Conversion

I have an API service written in .NET that needs to be converted to .NET Core. The project has a few third-party libraries, so familiarity with these is a plus. It's crucial that the new API retains all the functionality of the original.

Ideal Skills and Experience:
- Proficiency in .NET and .NET Core
- Experience with API development
- Familiarity with desktop application user interface interactions
- Knowledge of third-party libraries used in .NET
- Attention to detail for maintaining API functionality
