Accessing the UserManager Object in ASP.NET Identity Web Forms

In modern web development, user management is crucial for applications. When using ASP.NET Identity with Web Forms, many developers encounter a common problem: how to access UserManager to retrieve user information, such as the username of a non-current user. This guide outlines a step-by-step approach to solving this issue effectively.

Understanding the Problem

When you're working with ASP.NET Identity in a Web Forms application, you may need to access user information for users that are not currently logged in. This is where the UserManager comes into play. The UserManager class is responsible for managing user accounts, and provides methods to fetch user details, but accessing this object might not be straightforward, particularly for those new to ASP.NET Identity.

The Challenge

Your specific challenge here is to find the UserManager object in a Web Forms context. You need it to utilize methods like FindById to fetch user information using their unique identifier, or userID, but the UserManager isn't readily exposed in the method you are using.

The Solution

To retrieve the UserManager, you can create an instance of it using a UserStore. Follow these steps to implement the solution effectively:

Step-by-Step Implementation

Create UserStore Instance: Start by creating an instance of the UserStore. The UserStore utilizes the default connection string named DefaultConnection.
