User Story 1565289: [MIEngine Natvis] Support multiple natvis files in visualizerFile launch configuration

I think you want to remove the set and backing field and just have:

        /// <summary>
        /// Collection of natvis files to use when evaluating
        /// </summary>
        public List<string> VisualizerFile { get; } = new List<string>();

Why do we not want the set()?

Why do we not want the set()?

Generally, properties with a collection type shouldn't have a set method. Instead, they get assigned in the constructor and items are added to them.

        }

This is still active.

If it makes your life easier, you can allow a set method, but in this case I would make these other changes:

• Still initialize the backing field to an empty collection so you don't need those null checks.
• Only allow set if the backing field is still an empty collection

The reason I allowed for set is due to the VisualizerFiles assignment in other places throughout the codebase such as the one shown below:

We can disallow the ability to set VisualizerFiles though if you deem it fine.

You can let LaunchOptions.VisualizerFiles be created during the constructor and it will be empty. When we need to assign/pass the Users strings you can use this.VisualizerFiles.AddRange(option.VisualizerFiles).
