Programatically adding "Birthday" to Google Contacts using Google contact API?

I am trying to add "Birthday" value to Google Contact using Google Contact API (C#). Can anyone help me out her开发者_运维知识库e.

I am using Google Data API Setup(1.4.0.2). I got one solution as specified on this link

But to implement accepted solution i need to upgrade to the latest version of the client library i.e API 3.0.

But for .Net i am not getting Version 3 API. What should i do in such situation?

Thanx

The answer is here:

The .NET client library only uses Version 2... Birthday API functions are availble in Verison 3. My suggestion is to recompile the .NET client library using Version 3 of the API and try to iron out a few things of the errors yourself. It's a good exercise for fun and certainly not impossible.

Much better answer than just saying "It's impossible".

You might want to check the API Documentation of Google Contact APIs for .NET.

There is an example on that Exact page on how you add contacts.
