验证.Net后端服务器中的Google ID令牌

所以，我有一个Java脚本和一个.NET后端.在Javascript中，当用户登录时，我会获取Google ID令牌，我想将其传递给后端，并且: 1)验证令牌 2)提取电子邮件，用户名等.

So, I have a Java-script and a .NET backend. In the Javascript i fetch the Google ID token when the user log in and the I would like to pass this to the backend and: 1) Validate the token 2) Extract the email, username etc.

这在Java文档中进行了解释: https://developers.google.com/identity/sign-in/web/backend-auth

This is explained in documentation for java: https://developers.google.com/identity/sign-in/web/backend-auth

主要是:

GoogleIdToken idToken = verifier.verify(idTokenString);

GoogleIdToken idToken = verifier.verify(idTokenString);

并且:

字符串email = payload.getEmail();

String email = payload.getEmail();

在Java中是如此简单！但是在.NET中该怎么办?我找不到文档！我找到了以下线程，但似乎是一个非常复杂的解决方案.那真的是最简单的方法吗?

So simple in Java! But what to do in .NET? I cannot find the documentation! I found the following thread, but it seems like a quite complicated solution. Is that really the most easy way?
