No way to avoid IDP selection prompt when invoking "edit profile" policy in B2C?

[DaRosenberg]

My app is a Xamarin.iOS app targeting an AAD B2C tenant.

To invoke the AAD B2C "edit profile" policy, it seems we need to specify an explicit authority in the call to AcquireTokenAsync(), using one of the overloads that accept an authority parameter.

However, all 4 overloads that accept an authority parameter, also require the behavior parameter, and because the UIBehavior type is a struct it cannot be supplied as null. Nor does it have any static fields to initialize an empty/zero behavior.

As a result, we have to specify either SelectAccount, ForceLogin or Consent, and in my testing, all of them results in the IDP selection UI being displayed before the actual profile edit UI.

How can we avoid showing an IDP selection UI in AAD B2C and instead directly present the user with the actual profile edit UI?

  I believe that this is on the backlog to try and fix this. @negoe : can you please confirm?

@henrik-me another good one;

@jmprieur : makes sense to investigate options.

Proposal is to add a new constant named NoPrompt to the UIBehavior structure.
When the uIBehavior parameter is be set to NoPrompt in overrides of AcquireTokenAsync on public client application, MSAL.NET won't send a prompt=xxx clause any longer.

This is now solved in MSAL.NET 2.6.0
