The expected result after running this code is that the member.Roles collection will be populated with the member's roles.

var member = await MemberManager.GetCurrentMemberAsync();
var userData = new
{
    member.Id,
    member.Email,
    member.Name,
    Roles = member.Roles.Select(x => x.RoleId).ToArray()
};

However, when stepping through the code the member.Roles collection is empty.

Changing the code to fetch the roles by calling MemberManager.GetRolesAsync(member) directly does return the expected collection.

var member = await MemberManager.GetCurrentMemberAsync();
var roles = await MemberManager.GetRolesAsync(member);
var userData = new
{
    member.Id,
    member.Email,
    member.Name,
    Roles = roles.ToArray()
};

However, when stepping through the code I see that now the member.Roles collection is populated.

It's not clear if this is the intended usage or a bug.

Some more contextual information:

• This logic is a snippet from a method defined in an abstract class that extends Umbraco.Cms.Web.Common.Views.UmbracoViewPage
• Views that implement the abstract class (using the @inherits directive) will call this method as any other helper method in a Razor page.
• The IMemberManager instance is being resolved by calling Context.RequestServices.GetRequiredService<IMemberManager>()
