Updates to get the code working

[bdrajer]

Hi,

There's a couple of things that need to be updated to get the sample working - at least for me, and I'm using an MS Office subscription.

Firstly, the steps to register the application in the README file are wrong. The portal linked there (apps.dev.microsoft.com) is for adding Office applications and doesn't allow adding custom new ones. This seems to have been replaced by Azure, and the URL that worked for me is https://aka.ms/AppRegistrations/?referrer=https%3A%2F%2Fdev.onedrive.com ... There's a short explanation here: https://learn.microsoft.com/en-us/onedrive/developer/rest-api/getting-started/app-registration?view=odsp-graph-online . In addition to that, I had to add a web platform in the authentication section for the app and specify a return URL (seems that any one would do).

Also, the target framework version in the C# project need to be updated to 4.6.2, otherwise the login throws a 'The underlying connection was closed' exception, it seems that an old TLS version was being used or something like that.

Hi bdrajer,

Based on your comments it seems you got this app working. Can you share a copy of your working solution project? I am trying to get it working, but no success. Thx.

Hi,

I changed only two things in the source code, the framework version (from 4.5.1 to 4.6.2, to get rid of the "underlying connection was closed" exception) and the MsaClientId (which needs to be set anyway). The biggest problem for me was the outdated README, so if you manage to register the app correctly with the portal I would expect the app itself to work. This did take some tinkering but by going step by step and asking Google for solutions when I ran into problems I was able to pull it off... The page I linked above was the key part of it.

Thx for your response. I am facing like 25 errors, most errors coming from the FormBrowser class. What version MS Graph are you running to have this work? The latest version of Graph(5.47 or .48) requires a higher version of .NET framework (4.7 or higher)

[bdrajer]

Sounds like you're missing some SDK, probably WinForms... My packages.config is unchanged, so all NuGet packages are the default versions. I pulled the sample once again and it builds with no modifications at all, the application runs and I can even open the login dialog - and only then the problems begin due to unrecognised application ID and old TLS.

I've already done the app registration done in Azure. The aim is getting the source code work to work. From the nuget pkg the sample seems to be running Graph 1.21 which is extremely old. Is that version Graph even still supported? Also you mentioned "In addition to that, I had to add a web platform in the authentication section for the app and specify a return URL (seems that any one would do)." How and where are you doing this?

[bdrajer]

I know nothing about Graph, but supposedly it's a REST API so it could be backward compatible. I haven't made any modifications to the NuGet packages, the project builds and works with packages referenced in the last version of the source.

The link I posted states the steps needed for app registration and it mentions registering a mobile platform. In addition to that, I had to add a web platform to make it work (can't remember if the mobile platform that they mentioned was really needed).

I got it to run. My problem now is the Authentication piece. Error is: We're unable to complete your request
invalid_request: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is a URI which matches a redirect URI registered for this client application. I think this has to do with the web platform you mentioned. What is the exact url synteax you used? The source code has: public const string MsaReturnUrl = "urn:ietf:wg:oauth:2.0:oob"; Don't think thats a valid URI.

I now got it working completely and it's loading the OneDrive contents. One of the default Redirect Uri is what did it for me. This would be flawless if it work with the latest Graph API version, because many of the syntax are deprecated in the new NuGet releases. Thx for helping out.
