> C# Union schema is unable to handle same type names with different namespaces. It's throwing "SchemaParseException("Duplicate type in union: "...) exception.
> In the below code, key of uniqueSchemas should be FullName of the type which is similar to Java implementation. 
> internal static UnionSchema NewInstance(JArray jarr, PropertyMap props, SchemaNames names, string encspace)
>         {
>             List<Schema> schemas = new List<Schema>();
>             IDictionary<string, string> uniqueSchemas = new Dictionary<string, string>();
>             foreach (JToken jvalue in jarr)
>             {
>                 Schema unionType = Schema.ParseJson(jvalue, names, encspace);
>                 if (null == unionType)
>                     throw new SchemaParseException("Invalid JSON in union" + jvalue.ToString());
>                 string name = unionType.Name;
>                 if (uniqueSchemas.ContainsKey(name))
>                     throw new SchemaParseException("Duplicate type in union: " + name);
>                 uniqueSchemas.Add(name, name);
>                 schemas.Add(unionType);
>             }
>             return new UnionSchema(schemas, props);
