Blazor is a popular framework for building interactive web applications using C# of JavaScript. It is on top of ASP.NET, which provides a robust and platform for web development. However, sometimes developers may encounter issues with Blazor's ASP.NET Identity scaffolding not working as expected. In this article, we will explore some possible solutions to this problem.

Check ASP.NET Identity Configuration

The step in troubleshooting the ASP.NET Identity scaffolding issue is to ensure that the configuration is set up correctly. This includes checking the connection , database provider, and other relevant settings. Here is an example of how the configuration should look like:

public void ConfigureServices(IServiceCollection )
    services.AddDbContext(options =>

    services.AddDefaultIdentity(options => options..RequireConfirmedAccount = true)

Verify Database Connection

If the ASP.NET Identity scaffolding is still not working, it is important to verify that the application can connect to the database. This can be done by checking the connection string and ensuring that the database server is running. Additionally, it is recommended to check the database schema and make sure that it matches the ASP.NET Identity requirements.

Update NuGet Packages

Another common cause of ASP.NET Identity scaffolding issues is outdated or incompatible NuGet packages. It is important to regularly update the packages used in the project to ensure compatibility and stability. To update the packages, open the NuGet Package Manager in Visual Studio and click on “Updates” to see if there are any available updates for the installed packages. Update the packages and rebuild the project to see if the issue is resolved.

Reinstall ASP.NET Identity

If none of the above solutions work, it may be necessary to reinstall the ASP.NET Identity scaffolding. This can be done by removing the existing scaffolding and then adding it back to the project. To remove the scaffolding, open the Package Manager in Visual Studio and run the following command:

Scaffold- "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -Force

Replace “YourConnectionString” with the actual connection string for your database. After removing the scaffolding, add it back to the project by running the following command:

Scaffold-DbContext "YourConnectionString" Microsoft.AspNetCore.Identity.EntityFrameworkCore -OutputDir Models -Force

, replace “YourConnectionString” with the actual connection string for your database. After adding the scaffolding back, rebuild the project and see if the issue is resolved.


ASP.NET Identity scaffolding is a powerful tool for managing user authentication and authorization in Blazor applications. However, it may encounter issues at times. By following the steps outlined in this article, you should be able to troubleshoot and resolve most ASP.NET Identity scaffolding issues.
