It might need some cleanup to handle edge cases, errors, etc.

You need to get the progids for a given extension and use that to look up the handler.

If you are on Windows and want to look up the available file type handlers, you can do that via the Windows registry.

✅ Class instance reference
Like a classic bug is this: 
public struct Point
{
    public int X { get; set; }
    public int Y { get; set; }
}

public class Widget
{
    public Point Location { get; set; }
}
public struct Point
{
    public int X { get; set; }
    public int Y { get; set; }
}

public class Widget
{
    public Point Location { get; set; }
}
and then you have code like this: 
var w = new Widget();
w.Location.X = 42;
var w = new Widget();
w.Location.X = 42;
...and it doesn't get "updated" because of copy semantics with value types.

Unless you have some struct copy thing happening.

I think you are either doing something wrong or completely mis-diagnosing the issue because changing the value of a member of a reference type will absolutely update the instance being referred to 🙂

Variable capture in a closure could be an issue, yeah.

Then the reference you are using is to change the value of the member must be pointing to a different instance.

There is no "snapshot" behavior for reference types.

What you are describing only makes sense if it's a struct.

I have no opinion on Unity but it uses an older non-modern version of .NET and C# and folks here who are familiar with it say don't try to learn Unity until you have a good grasp of C# itself.

I probably learned C# before you were born so I'm not too up to speed on the most recent books, but The C# Players Guide and Head First C# both have good reputations.
