GoogleScope is not declared

Question

I'm trying to access a Gmail account with OAuth. Following the example of
https://www.limilabs.com/blog/oauth2-gmail-imap-installed-applications
- I use nuget to download the Google.Apis.Auth package
- Register the application
- I put the imports namespaces

Imports Google.Apis.Auth.OAuth2
Imports Google.Apis.Auth.OAuth2.Flows
Imports Google.Apis.Auth.OAuth2.Requests
Imports Google.Apis.Auth.OAuth2.Responses

Imports Limilabs.Client.Authentication.Google

Imports Limilabs.Client.IMAP

Below I put:

Dim clientID As String = "XXX.apps.googleusercontent.com"
Dim clientSecret As String = "IxBs0g5sdaSDUz4Ea7Ix-Ua"

Dim clientSecrets = New ClientSecrets With { _
     .ClientId = clientID, _
     .ClientSecret = clientSecret _
}

Dim credential = New GoogleAuthorizationCodeFlow( _
     New GoogleAuthorizationCodeFlow.Initializer With { _
         .ClientSecrets = clientSecrets, _
         .Scopes = { _
             GoogleScope.ImapAndSmtp.Name, _
             GoogleScope.UserInfoEmailScope.Name}_
})

But the word GoogleScope in the last 2 lines tells me that it is not declared, what am I missing?
Thanks.

Answer 1

GoogleScope class is declared in Limilabs.Client.Authentication.Google namespace.

You need to import it.

I already have that namespace imported, and that class does not exist. My version of mail.dll is somewhat old, it is 3.0.12102.1426, is this the problem?

This is very old version.
