C# - Why Is System.Data.Services.MimeTypeAttribute Now Only A Class Level Attribute

I'm getting started with Astoria/ADO.NET Data Services/WCF Data Services. Looking through a lot of the code samples out there, it appears that the MimeType attribute used to be a method level attribute. After installing the latest update, it is now a class level attribute.

If I have more than one Service Operation that I want to return as a certain MimeType, then it appears now that I have to create a new service for each operation. Is this correct?

Most examples are like this:

[WebGet]
[SingleResult]
[MimeType("application/pdf")]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}

I get "Attribute 'MimeType' is not valid on this declaration type. It is only valid on 'class' declarations." when I compile, because now I can't do this.

Now, I have to do this:

[MimeType("FooPDF", "application/pdf")]
public class FooService : DataService<FooDBEntities>
{
public static void InitializeService(DataServiceConfiguration config)
{
config.SetServiceOperationAccessRule("FooPDF", ServiceOperationRights.All);
}
[WebGet]
[SingleResult]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}
}

What's worse is that I can't add duplicate MimeType attributes to my class.
