Integrating Azure AD into a Windows desktop application using interactive authentication

There's a newer version of this sample taking advantage of the Microsoft identity platform (formerly Azure AD v2.0) and MSAL.NET.

Check it out: https://github.com/azure-samples/ms-identity-dotnet-desktop-msgraph.

If you really need to access this Azure AD v1.0 | ADAL.NET sample, you can navigate to the master branch, but please know that it's no longer supported.
