I suspected you overlook that it's an array. So you can either put them in array or List like so

ValidationModelData[] validations = JsonConvert.DeserializeObject<ValidationModelData[]>(validation.JsonMetaData);

You are converting JSON array to C# object. You have to use array or list. I prefer List over array, because if you want to add/remove ValidationModelData then resizing arrays is expensive.

List<ValidationModelData> validations = JsonConvert.DeserializeObject<List<ValidationModelData>>(validation.JsonMetaData);
