It really helped me get started with DI in .NET. using Microsoft.AspNetCore.Mvc.Versioning; This is the way I would do it: EF Core is an object-relational mapping (ORM) framework that simplifies the data During the build phase, I need to add a certificate from Azure Key Vault and also log the thumbprint. ? Before writing any code we need a NuGet package for dependency injection components: Microsoft.Extensions.DependencyInjection. Without Injection doing a unit test for your app is more than trivial as you need to understand the inner workings of the dependency implementation. middleware expects to find static files. First you need to add StructureMap to your project.json dependencies: Now we'll update our static void main to use StructureMap for registering our custom dependencies: At first glance this may seem more complicated than the previous version, and it is, but it is also far more powerful. www.partnercomm.net webBuilder Building a Console App with .NET Generic Host. using Microsoft.Extensions.DependencyInjection; Once you have created the app object and setup your logger it should be easy to pass the thumbprint value into your logger. Use ServiceCollection to add dependencies and after to return the service provider.

System.ArgumentException: Argument passed in is not serializable. Add a reference to Class library dll to your ASP.NET MVC Core application. Implementing key vault as follows: The call to AddAzureKeyVault fails with the error below: Azure.Identity.AuthenticationFailedException No matter what I try, visual studio 2022 I thows; "Unable to access the Azure App Configuration provider. It's not necessary to explicitly apply the [FromServices] attribute to a parameter. By Kirk Larkin, Steve Smith, and Brandon Dahler.
