Uploading PBIX File in C# sample (HELP!)

Hi brunozanoelo 

You don't really need redirect url for a native app. All you need to use the usercredential approach which is commented on the code you need to uncomment that. Because powerbi no longer support the client id with out Azure AD registration.

 // create new ADAL authentication context 
      var authenticationContext =
        new AuthenticationContext(ProgramConstants.AzureAuthorizationEndpoint);

            //use authentication context to trigger user login and then acquire access token
            //var userAuthnResult =
            //  authenticationContext.AcquireTokenAsync(ProgramConstants.PowerBiServiceResourceUri,
            //                                          ProgramConstants.ClientID,
            //                                          new Uri(ProgramConstants.RedirectUri),
            //                                          new PlatformParameters(PromptBehavior.Auto)).Result;


            // use authentication context to trigger user sign-in and return access token 
            var userCreds = new UserPasswordCredential("[email protected]", "myEasyToCrackPassword");

            var userAuthnResult = authenticationContext.AcquireTokenAsync(ProgramConstants.PowerBiServiceResourceUri,
                                                                          ProgramConstants.ClientID,
                                                                          userCreds).Result;

Update your username and password in the userpasswordcredentials
