ASP.NET Core Blazor Server: Handling State Management with a Custom Service Across Multiple Components
I'm currently working on an ASP.NET Core Blazor Server application and I'm facing challenges with state management across multiple components. I have created a custom service to manage a user profile but I'm running into issues where the state does not seem to persist as expected across different components. Here’s a basic structure of my custom service: ```csharp public class UserProfileService { private UserProfile _userProfile; public UserProfile GetUserProfile() => _userProfile; public void SetUserProfile(UserProfile profile) { _userProfile = profile; } } ``` I register this service in the `Startup.cs` like this: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddRazorPages(); services.AddServerSideBlazor(); services.AddSingleton<UserProfileService>(); } ``` In one component, I attempt to set the user profile: ```razor @inject UserProfileService UserProfileService <button @onclick="UpdateProfile">Update Profile</button> @code { private void UpdateProfile() { UserProfileService.SetUserProfile(new UserProfile { Name = "John Doe" }); } } ``` Then, in another component, I try to retrieve the profile: ```razor @inject UserProfileService UserProfileService <h3>User Profile</h3> <p>@UserProfileService.GetUserProfile()?.Name</p> ``` However, when I update the profile in the first component and navigate to the second component, the displayed name remains `null` or empty. I’ve checked that the service is properly registered as a singleton, so I expect it to maintain the state across components. One thing I noticed is that when I refresh the page, the data resets, which is not the behavior I expected. Has anyone faced similar issues with state management in Blazor Server? What am I missing here? I would appreciate any insights or best practices on how to correctly manage state in this scenario.
