input includes member definitions that are not available on the target type.

InvalidOperationException

input contains a "__type" property that indicates a custom type, but the type resolver that is currently associated with the serializer cannot find a corresponding managed type.

-or-

input contains a "__type" property that indicates a custom type, but the result of deserializing the corresponding JSON string cannot be assigned to the expected target type.

-or-

input contains a "__type" property that indicates either Object or a non-instantiable type (for example, an abstract type or an interface).

-or-

An attempt was made to convert a JSON array to an array-like managed type that is not supported for use as a JSON deserialization target.

It is not possible to convert input to the target type.

This deserialization method does not try to cast the root of the object graph to a specific type, as with the Deserialize(Of T) method.
