Steps to reproduce

1. Create a class that derives from Dictionary<string, object>:

   public class Metadata : Dictionary<string, object>
   {
     // ...
   }
   

2. Create a GraphQL object type for that class and specify some fields:

   [ObjectType]
   public sealed class MetadataType : ObjectType<Metadata>
   {
     protected override void Configure(IObjectTypeDescriptor<Metadata> descriptor)
     {
       descriptor
         .BindFieldsExplicitly();
   
       descriptor.Field("all")
         .Type<NonNullType<ListType<NonNullType<MetadataEntryType>>>>()
         .Resolve(ctx => ctx.Parent<Metadata>().Select(e => new MetadataEntry(e.Key, e.Value)));
   
       descriptor.Field("value")
         .Argument("key", a => a.Type<NonNullType<StringType>>())
         .Type<JsonType>()
         .Resolve(ctx => ctx.Parent<Metadata>().TryGetValue(ctx.ArgumentValue<string>("key"), out var value) ? value : null);
     }
   }
   
   public record MetadataEntry(string Key, object? Value);
   
   [ObjectType]
   public sealed class MetadataEntryType : ObjectType<MetadataEntry>
   {
     protected override void Configure(IObjectTypeDescriptor<MetadataEntry> descriptor)
     {
       // ...
     }
   }
   

3. Try to access the new field:

   query {
     metadata {
       all {
         key
         value
       }
   
       key1: value(key: "key1")
       key2: value(key: "key2")
       key3: value(key: "key3")
     }
   }
   

What is expected?

The specified resolver is called once per Metadata object (in this example) and successfully receives the actual object (as Metadata in this example) by calling ctx.Parent<Metadata>().

It is not automatically resolved as a list, which would violate the specified schema.

What is actually happening?

The specified resolver is invoked for each element of the enumerable object and receives System.Collections.Generic.KeyValuePair`2[System.String,System.Object] (in this example) by calling ctx.Parent<Metadata>()

Exception has occurred: CLR/HotChocolate.GraphQLException
An exception of type 'HotChocolate.GraphQLException' occurred in HotChocolate.Execution.dll but was not handled in user code: 'The resolver parent type of field `Metadata.value` is `System.Collections.Generic.KeyValuePair`2[System.String,System.Object]` but the resolver requested the type `HotChocolateIssue.Metadata`. The resolver was unable to cast the parent type to the requested type.'
