Description

Using the csharp generator with an array of objects produce code that cannot be compiled.

I have provided a minimal file to reproduce the problem and an example of the generated code that doesn't compile.

I have also provided the manual fix I need to do everytime I generate code

basically, it's just a minor fix to change:
List<Dictionary>
to
List<Dictionary<string, object>>

Steps to reproduce

Suggest a fix

The generated code is like this:

        public NotificationtestGetElementsV1ResponseMPayload(int pkiNotificationtestID = default(int), List<Dictionary> aObjVariableobject = default(List<Dictionary>))

It should be like this:

        public NotificationtestGetElementsV1ResponseMPayload(int pkiNotificationtestID = default(int), List<Dictionary<string, object>> aObjVariableobject = default(List<Dictionary<string, object>>))

Thanks in advance
