ACCESS ONEDRIVE

Question

I have an MS account and use OneDrive. I am developing a .NET MAUI (8.0) app that should be able to access a specific folder in my OneDrive and download/upload files in this folder. The only authorization required should be my MS account.

This task seems simple, but in reality I am stuck with a lot of problems.

To begin with, I tested the old OneDriveApiBrowserSample for desktop, and it works fine. Then I tried to migrate this code to MAUI, but VS reports unexpected errors: for instance it does not recognize the class DelegateAuthenticationProvider, which according to the documentation should be available in Microsoft.Graph - in fact, it runs with OneDriveApiBrowserSample.

Then I resumed the old GraphTutorial for Xamarin, that I had successfully tested a few years ago - but VS reports the same kind of errors as above.

Browsing the online documentation only increased my confusion, as I find several articles that are obsolete. What is the state of the art approach for my (not-so-simple) requirement?

Answer 1

Hello,

DelegateAuthenticationProvider is no longer a suitable authentication method as an AuthenticationProvider.

Please refer to this document to select the appropriate AuthenticationProvider as the authentication method according to the usage scenario.

• Choose a Microsoft Graph authentication provider based on the scenario.

Best Regards,

Alec Liu.
