How do I get the Visual Studio Online credentials cached in the registry? http://stackoverflow.com/questions/20809207/how-do-i-get-the-visual-studio-online-credentials-cached-in-the-registry

ByUsingTfsClientCredentialsStorage.fsx

#r "Microsoft.TeamFoundation.Client"
#r "Microsoft.VisualStudio.Services.Common"
#r "System.Net.Http"

open System
open Microsoft.TeamFoundation.Client

// retrieve VssToken

// for the logged in user "IdeUser"
let vssTokenIdeUser = TfsClientCredentialStorage.RetrieveConnectedUserToken()

let tokenStorage = Microsoft.VisualStudio.Services.Common.TokenStorage.VssTokenStorageFactory.GetTokenStorageNamespace "VisualStudio"
let vssTokens = tokenStorage.RetrieveAll "VssApp" |> Array.ofSeq
for t in vssTokens do
    printfn "%s %s %s %s" t.Resource t.Type (t.GetProperty "UserId") (t.GetProperty "UserName")

// create a TfsClientCredentials by retrieving an IssuedToken

let ccs = TfsClientCredentialStorage()
let ct = ccs.RetrieveToken(Uri "https://ctaggart.visualstudio.com", Microsoft.VisualStudio.Services.Common.VssCredentialsType.Federated) :?> CookieToken
let cc = CookieCredential(false, ct)
let tcc = TfsClientCredentials cc

// use the TfsClientCredentials to authenticate with 

let tfs = new TfsTeamProjectCollection(Uri "https://ctaggart.visualstudio.com/DefaultCollection", tcc)
tfs.Authenticate()

Interesting.

One question, what package you downloaded to use "Microsoft.VisualStudio" namespace.
I'm not found this, can you help me ?
