      Description

      Given the class and enum:

      class Person
      {
      	public Color FavoriteColor { get; set; }
      }
       
      enum Color
      {
      	Blue,
      	SomethingElse
      }
      

      The following code snippet will not work:

      Builders<Person>.IndexKeys.Ascending(x => x.FavoriteColor);
      Builders<Person>.Filter.Eq(x => x.FavoriteColor, Color.Blue);
      // other builders as well
      

      Workaround

      Use the string field name of the member. Even if you have mapped it to a different element name, as long as the member name is used, it will still get mapped:

      Builders<Person>.IndexKeys.Ascending("FavoriteColor");
