Error at when calling below method to get AccessToken
return authContext.AcquireToken(this.PowerBiAPI, this.ClientID, new Uri(this.RedirectUrl)).AccessToken;
Error is :

Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application. at Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.RunAsyncTask[T](Task`1 task) at DSLUI.Controllers.BusinessLogic.ReportService.GetAccessToken()
Here this.ClientID is generated for App Type: Native

Solved! Go to Solution.
As i am using App type Native,AAD popup comming at server side causing this issue.
Then i changes it to App Type to Web app, and getting access token using below code, Issue got resolved.
public async Task<string> GetAccessToken() { try { var password = Utility.Decrypt(this.PWBI_Psw); var content = new FormUrlEncodedContent(new[] { new KeyValuePair<string, string>("grant_type", "password"), new KeyValuePair<string, string>("scope", "openid"), new KeyValuePair<string, string>("username", this.PWBI_User), new KeyValuePair<string, string>("password", password), new KeyValuePair<string, string>("client_id", this.ClientID), new KeyValuePair<string, string>("client_secret", this.ClientSecretKey), new KeyValuePair<string, string>("resource", this.PowerBiAPI) }); string tokenEndpointUri = string.Format(this.TokenEndpointUri, this.TenantID); using (var client = new HttpClient()) { HttpResponseMessage res = client.PostAsync(tokenEndpointUri, content).Result; string json = await res.Content.ReadAsStringAsync(); var obj = JObject.Parse(json); var AccessToken = (string)obj["access_token"]; return AccessToken; } } catch (Exception ex) { throw ex; } }
