 | **ExcludeByTypeName** | Sets this value to exclude types from being registered by their full name. You can use '*' wildcards. You can also use ',' to separate multiple filters. |
 | **ExcludeByAttribute** | Excludes matching types by the specified attribute type being present. |
 | **KeySelector** | Sets this property to add types as keyed services. This property should point to one of the following: <br>- The name of a static method in the current type with a string return type. The method should be either generic or have a single parameter of type `Type`. <br>- A constant field or static property in the implementation type. |
-| **CustomHandler** | Sets this property to invoke a custom method for each type found instead of regular registration logic. This property should point to one of the following: <br>- Name of a generic method in the current type. <br>- Static method name in found types. <br>This property is incompatible with `Lifetime`, `AsImplementedInterfaces`, `AsSelf`, and `KeySelector` properties. |
