Description

Hi.
When generating an API spec with the C # generator, I would like to have the "_id" field created. However, the generator creates the property "Id" from this. Can this problem be fixed? I absolutely need the property name "_id".

Thank you.

Research direction

Start with the C# generator and reproduce the reported OpenAPI case where a property named "_id" becomes "Id". Trace the property-name handling and identify the relevant generator tests, if present. Done means the generated C# property retains the requested "_id" name without breaking existing naming behavior.
