[Feature Request] Support for public clients (Authorization code grantype workflow) in MSAL.NET

[dishantbuch]

MSAL client type

Public

Problem statement

Background:

We/Altera team is working on adding the Third-party Identity federation support in our product and we are considering ADFS, EntraID, OCTA, Auth0 etc.
To achieve this integration, we have started working on a POC (Proof Of Concept) using MSAL.
Currently we are using MSAL (Microsoft Authentication library) for federating to ADFS & EntraID.
We are now extending this POC to also federate to OCTA and Auth0.
Query/Need Information

Recently, MSAL.NET introduced support for both the public client and client credential workflows for non-Microsoft/third-party IDPs like Okta:

#1538

The Confidential Client support became generally available (GA) in MSAL.NET version 4.6, whereas Public Client support remains in the experimental phase.

Based on our review of the latest codebase, the Public Client functionality still appears to be marked as experimental.

Proposed solution

Request for Clarification from Microsoft

At this stage, we would like to get more clarity on Microsoft’s future strategy regarding MSAL.NET support for third-party IDPs. Specifically:

Will full support for third-party IDPs be provided in future MSAL.NET releases?
Is there a roadmap or commitment to stabilize current experimental features (e.g., Public Client workflow) for broader compatibility?

Alternatives

If MSAL is not supporting third party IDPs for Authorization code grantype workflow then can Microsoft suggest any other OIDC client library that can be used instead of MSAL?

Support for non-Microsoft IDPs is best effort only for confidential client. We will generally ask the community to propose fixes.

Microsoft IDPs such as Entra have complex scenarios like multi-tenancy. But if you do not need those, a general purpose SDK will work.

I understand that MS generally ask the community to propose a fixes and thanks for claryfing that my friend. I would like to know whether adding official support for public client support (For authorization code grant workflow) in MSAL is in future roadmap and it will always be like - "Can be used"?
