Solved Issue: Unable to find the required services. Please add all the required services by calling 'IServiceCollection.AddHealthChecks'

I am using ASP.NET Core 5, .NET Core 3.0.100, and Visual Studio 2022 Community. I followed the Microsoft guide and added endpoints.MapHealthChecks("/health") in my Startup.cs, but I'm encountering the following error:

Message=Unable to find the required services. Please add all the required services by calling 'IServiceCollection.AddHealthChecks' inside the call to 'ConfigureServices(...)' in the application startup code Source=Microsoft.AspNetCore.Diagnostics.HealthChecks

In our application, we encountered an error related to adding all the required services by calling 'IServiceCollection.AddHealthChecks'.

To resolve this issue , you need to ensure that you have properly configured health checks in ASP.NET Core application.

Here's a step-by-step solution to address this issue:

1. First, ensure that you have the necessary NuGet packages installed for health checks. You can install them using the following command in the NuGet Package Manager Console:

Install-Package Microsoft.Extensions.Diagnostics.HealthChecks

2. Next, navigate to your application's Startup.cs and in case .NET>=6 then program.cs file.
3. Inside the ConfigureServices method, make sure to add health checks using the AddHealthChecks method. This method is typically called on an instance of IServiceCollection.

    public void ConfigureServices(IServiceCollection services)
    {
        // Other service configurations
        
        services.AddHealthChecks();
        
        // Additional service configurations
    }
    

4. You can also configure specific health checks by chaining methods to the AddHealthChecks call. For example:

    services.AddHealthChecks()
            .AddCheck("DatabaseHealthCheck", new DatabaseHealthCheck())
            .AddCheck("ExternalServiceHealthCheck", new ExternalServiceHealthCheck());
  

This code ensuring that the required services are added using IServiceCollection.AddHealthChecks, you should be able to resolve the error related to health checks in your ASP.NET Core application.
