How to get Claims for multiple users with AspNetCore.Identity?

Question

In my .NET 6 application I want to display all users with their claims.

Currently I use the UserManager to get all users like this:

var users = await _userManager
      .Users
      .AsNoTracking()
      .ToListAsync(cancellationToken);

Then I loop through all the users and call await _userManager.GetClaimsAsync(user) to get the claims for each user.

This results in many database requests as a request gets fired for every user. When there are multiple thousand users present it really harms the performance.

Is there a better way to do these kind of bulk operations with AspNetCore.Identity?

Answer 1

if role-related services are enabled and claims are related to roles you can use

var users = await _userManager.GetUsersInRoleAsync("Role1");

otherwise, you will have to create navigational properties manually.
