error TF30063: Force prompt for credentials when connecting programmatically to visualstudio.com

Question

I'm aware of alternate credentials (Authenticating to hosted TFS: TF30063: You are not authorized to access .visualstudio.com) but I need users to be prompted for the credentials when connecting to visualstudio.com.

Similar in spirit to the code below, which does not work

var aTeamProjects = new TfsTeamProjectCollection(m_oTfsCollectionUri);
aTeamProjects.ClientCredentials.PromptType = CredentialPromptType.PromptIfNeeded;
aTeamProjects.Authenticate();

In the code above the Authenticate-request results in TF30063: You are not authorized to access .visualstudio.com.

It is a client app (e.g. windows form, console app) or a web app? Try it with var c = new VssClientCredentials(); TfsTeamProjectCollection _tfs = new TfsTeamProjectCollection(m_oTfsCollectionUri, c);_tfs.EnsureAuthenticated(); — starian chen-MSFT, Sep 07 '17 at 02:21

Does it prompt a window for authentication? You can clear credentials in Credential Manager, if doesn't work, clear C:\Users\[username]\AppData\Local\.IdentityService — starian chen-MSFT, Sep 14 '17 at 01:45
Are there related credentials in Credential Manager? (You can open a new thread for new issue/question) — starian chen-MSFT, Sep 15 '17 at 06:39

The solution is working on a new project with the code below. Then provide the credentials if it is asked when running an app.

var credentials = new VssClientCredentials();
credentials.PromptType = CredentialPromptType.PromptIfNeeded;
var aTeamProjects = new TfsTeamProjectCollection(m_oTfsCollectionUri, credentials);
aTeamProjects.EnsureAuthenticated();

Without ever being prompted for anything I kep getting: Microsoft.TeamFoundation.TeamFoundationServerUnauthorizedException: TF30063: You are not authorized to access vs.com ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized. – John Grabanski Jul 11 '18 at 20:38
@JohnGrabanski having the same problem with `VssClientCredentials` with 15.0 TFS client API. Have you found the reason ? [there is credentials prompt bug described](https://learn.microsoft.com/en-us/azure/devops/integrate/get-started/client-libraries/samples?view=azure-devops#visual-studio-sign-in-prompt-microsoft-account-or-azure-active-directory-backed-for-soap-services) – oleksa Apr 25 '19 at 07:46
