386Hello,
I got an email about "D365 Platform Modernization: Deprecate legacy authentication-WS-Trust" last week. I compared my code with the one mentioned in that email about how to determine that my code is using WS-trust， I found that I was using the OrganizationServiceProxy class，It belongs to ws-trust.
I found an article published in 2019 on the official website about how to use CrmServiceClient to connect to organizational services. Please see the following code. But I feel like this code also belongs to ws-trust, not Office 365.
I just want to make sure that the way I connect to the organization service given in the following code belongs to wstrust, and if it still belongs to ws-trust, if I want to change it based on the code in it, how do I need to change this code to change my security protocol from ws-trust to office 365?
static void Main(string[] args)
{
// e.g. https://yourorg.crm.dynamics.com
string url = "";
// e.g. you@yourorg.onmicrosoft.com
string userName = "";
// e.g. y0urp455w0rd
string password = "";
string conn = $@"
Url = {url};
AuthType = Office365;
UserName = {userName};
Password = {password};
RequireNewInstance = True";
using (var svc = new CrmServiceClient(conn))
{
WhoAmIRequest request = new WhoAmIRequest();
WhoAmIResponse response = (WhoAmIResponse)svc.Execute(request);
Console.WriteLine("Your UserId is {0}", response.UserId);
Console.WriteLine("Press any key to exit.");
Console.ReadLine();
}
}
