Answer 1

Couple of points:

1. The Org url should look like https://yourcrm.dynamics.com. Read more

2. The GitHub issue says:

https://login.microsoftonline.com/{Guid} (where the Guid is the tenant ID
or
https://login.microsoftonline.com/domainName where the domain name is a domain associated with your tenant
or
https://login.microsoftonline.com/common

    string organizationUrl = "https://yourcrm.dynamics.com";
    string appKey = "*****";
    string aadInstance = "https://login.microsoftonline.com/";
    string tenantID = "myTenant.onmicrosoft.com";
    string clientId = "UserGUID****";
    public Task SendData()
    {
        return AuthenticateWithCRM();
    }

    public async Task AuthenticateWithCRM()
    {
        ClientCredential clientcred = new ClientCredential(clientId, appKey);
        AuthenticationContext authenticationContext = new AuthenticationContext(aadInstance + tenantID);
        AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(organizationUrl, clientcred);
        using (HttpClient httpClient = new HttpClient())
            {
                httpClient.BaseAddress = new Uri(organizationUrl);

                .

                .
             }

    }
