How to get values out of SessionTokenStore in Controller and View

Question

In asp.net 4.8 MVC application, I've used MS Graph to get access token as shown below in Startup.Auth.cs. How do I access values stored in tokenStore in Controller and View. I'm not sure how to assign value from tokenStore to ViewBag.DIsplayName in controller.

var signedInUser = new ClaimsPrincipal(notification.AuthenticationTicket.Identity);
var tokenStore = new SessionTokenStore(confidentialClientApplication.UserTokenCache, HttpContext.Current, signedInUser);

string[] scopes = new string[] { "https://graph.microsoft.com/.default" };

var result = await confidentialClientApplication.AcquireTokenByAuthorizationCode(
	scopes, notification.Code).ExecuteAsync();

var userDetails = await GraphHelper.GetUserDetailsAsync(result.AccessToken);

tokenStore.SaveUserDetails(userDetails);

Hi @Joe Green,

According to your description, I want to confirm whether you are referring to this official example: https://github.com/microsoftgraph/msgraph-training-aspnetmvcapp/tree/main/Demos/03-add-msgraph/graph-tutorial

If this is the case, as we tested, this demo works normally, and the userDetails has been correctly obtained in BaseController and stored in ViewBag. This is test result：

This is the corresponding logic code ( In method onActionExcuting):

So I'm not sure at which step you have the problem. If possible, please provide more details.

Best regards,

Xudong Peng
