OAuth Authentication Code Flow Example Using C#/MSAL.NET & MSAL.js?

Question

I've been studying active-directory-b2c-javascript-nodejs-webapi and specifically index.js.

Has anyone translated this node.js script to C#/MSAL.NET? Perhaps there is already an example somewhere?

I was hoping for a single Visual Studio sln file that has the

1. javascript/MSAL.js front end served with a C#/ASP.NET/MVC project (instead of "npm start" for node.js to serve the javascript) and
2. a C#/ASP.NET/MVC/MSAL.NET WebAPI instead of this second node.js WebAPI to accept the bearer token. I could not find it at sample-v2-code. Perhaps I missed it?

If there is no such example, perhaps someone could point me to the MSAL.NET functions I might need?

Thanks

Answer 1

@Siegfried Heintze , Why would I mix node.js and ASP .Net application in one single solution, when they are two different Server -side languages. For B2C samples, if you plan to use ASP .net core or ASP .net with C# for developing Web Apps or Web APIs, you can check out the following samples:

ASP .Net Sample: https://github.com/Azure-Samples/active-directory-b2c-dotnet-webapp-and-webapi
ASP .Net core Sample: https://github.com/Azure-Samples/active-directory-b2c-dotnetcore-webapp

Both the Samples above uses MSAL for .net and .net core to acquire tokens from B2C.

Also I would like to share you the link where you can find samples available for B2C with various languages like Asp.Net, ASP .Net core, Node.js, and Python.:
https://learn.microsoft.com/en-us/azure/active-directory-b2c/code-samples#web-apps-and-apis

The sample-v2-code that you mentioned, that page contains the application samples for Azure AD and not for Azure AD B2C. Though there is not much difference in the code and the way the libraries are used, but still there are suttle differences like the endpoints etc.

You can find more details on MSAL (including the various platforms where MSAL is implemented) here: https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-overview

You would find all the supported languages and the various functions that can be used in with MSAL for the supported language platforms in that same URL.

Hope this helps.
