(VB.NET UWP/WinRT) SharePoint Online Authentication
Demonstrates how to authenticate with SharePoint Online. The end result of authentication is to establish an HTTP cookie, named "SPOIDCRL", that contains a binary security token to be sent in subsequent SharePoint HTTPS requests.
The SPOIDCRL cookie can be persisted to a file and re-used in subsequent application runs.
Important: This example uses a method, SharePointOnlineAuth, that is introduced in Chilkat v184.108.40.206.
Also Important: Chilkat realizes there may be cases where your situation is such that it does not work, and something additional is required to make it work. If the example does not work out-of-the-box, please send email to firstname.lastname@example.org. The information logged to the LastErrorText property has been carefully crafted to help solve problems quickly. Also, the JSON argument to the SharePointOnlineAuth method provides a means to include additional information, whatever it may be, to handle future unknown situations.
