Microsoft Graph for reading my own calendar in C#?

Question

I am not an expert on all things Azure, but I'd like to read my own calendar programmatically. I found some code to access Microsoft Graph and read my calendar, but it seems I have to create an App Registration first, is it possible to SKIP the app registration if I only need to read my OWN calendar? here's my starting point:

var scopes = new[] { "User.Read" };
var options = new TokenCredentialOptions
{
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};

var userName = "myaccount@company.com";
var password = "pwdhere";

var userNamePasswordCredential = new UsernamePasswordCredential(
    userName, password, tenantId, clientId, options);

var graphClient = new GraphServiceClient(userNamePasswordCredential, scopes);   

var events = await graphClient.Me.Calendar.Events
    .Request()
    .Filter("startsWith(subject,'All')")
    .GetAsync();

您需要注册应用程序，否则您甚至无法登录。如果它是您无法控制的 Azure AD，例如您的雇主，则需要让管理员为您创建。
