Suggestion: Support [IgnoreDataMember]

[Tornhoof]

Currently the [IgnoreMember] Attribute is used to annotate properties which should be excluded.
I suggest to additionally support [IgnoreDataMember] (which is part of System.Runtime.Serialization) to do the same.
Reason: Easier migration from other serializers and it would not be necessary to have the MessagePack library in all the projects with base types for serialization.

Yes, [DataContract] can be [MessagePackObject], [DataMember(Order)] as Int Key, [DataMember(Name)] as String Key.

The issue is that IgnoreDataMember is not part of .NET standard 1.4, so currently it can't be supported. However I can imagine it being added easily when future versions of .NET standard get released / ported to.

Really?
If I look into the nuget package https://www.nuget.org/packages/System.Runtime.Serialization.Primitives/ then the type is contained in .net standard 1.3

When you open up the solution and you attempt to use it (which I tried), it gives you a warning. My source is this: .NET Standard 1.4 API. I suppose @neuecc would need to add that package as dependency in order for this to work.

It is trivial to implement, there are around 4 places where you would need to add checks for it and that's about it.

[Tornhoof]

Yes, but since DataContract/member support is not yet in (atleast I get exceptions if I use DataMember(Order=1) instead of Key(1) and those attributes are actually define in System.Runtime.Serialization.Primitives I guess it will sooner or later show up anyway.

[AronParker]

Sure, if neuecc wants to add it I would help him if he likes.

[neuecc]

Thanks, I've added dependency(this is prepare workspace, not yet implemented).

IgnoreDataMember has been supported 1.1.2.
