> .NET binary writer doesn't get `System.Enum` field as an enum and uses
> `WriteObject()->Write()` instead of `WriteEnum()`.
> Consider:
> {code:c#}
> enum TestEnum {
> Foo, Bar
> }
> class TestClass {
> Enum enm = TestEnum.Foo;
>
> //Not
> //TestEnum enm = TestEnum.Foo;
> }
> cache.Put(key, new TestClass())
> {code}
> This code fails with the exception if 'enm' field declared as 'System.Enum'.
> I see 2 basis of the problem:
> # `System.Enum.IsEnum()` is false whereas certain enum like our 'TestEnum'
> returns True of course.
> # When e build user-type scheme, we rely on declared type of class field by
> FieldInfo. But not on real type of the field value. Here we get System.Enum
> with 'IsEnum==false'. When we serialize user-type object, we check type of
> the field instance. Here we get certain enum with 'IsEnum==true'.
> There are several approaches to fix this:
> 1) Refactor user-type scheme building to check filed value type instead of
> declared field type. Think doesn't worth `System.Enum`.
> 2) Fix `BinaryWriter.Write<T>(T obj)` so that it would check if `obj` is
> `System.Enum` and call `WriteEnum<T>(T val)`
> 3) Fix `BinarySystemHandlers.FindWriteHandler(Type type)` so that it deal
> with `SystemEnum`.
> 4) Fix `TypeCaster<T>.Cast<TFrom>(TFrom obj)` so that it deals with
> `System.Enum`.
> #4 looks the most universal to me.
> {code:c#}
> InvalidCastException: Specified cast is not valid: System.Enum ->
> System.Int32]
