How to migrate ASP.NET Core 5 code to ASP.NET Core 6

Microsoft’s ASP.NET Core 6, which has been available for production use since November 8, introduces a simplified hosting model that reduces the boilerplate code that you would otherwise need to write to get your ASP.NET Core application up and running. ASP.NET Core 6 makes a bit easier to create a new web application from scratch, compared with ASP.NET Core 5.

But what if you want to update an ASP.NET Core 5 project to ASP.NET Core 6? In that case, you should be aware of the code you will need to write to migrate ASP.NET Core 5 code to ASP.NET Core 6. This article presents several code samples that show how you can do this.

To work with the code examples provided in this article, you should have Visual Studio 2022 installed in your system. If you don’t already have a copy, you can download Visual Studio 2022 here.

Create an ASP.NET Core Web API project in Visual Studio 2022

First off, let’s create an ASP.NET Core project in Visual Studio 2022. Following these steps will create a new ASP.NET Core Web API 6 project in Visual Studio 2022:

1. Launch the Visual Studio 2022 IDE.
2. Click on “Create new project.”
3. In the “Create new project” window, select “ASP.NET Core Web API” from the list of templates displayed.
4. Click Next.
5. In the “Configure your new project” window, specify the name and location for the new project.
6. Optionally check the “Place solution and project in the same directory” check box, depending on your preferences.
7. Click Next.
8. In the “Additional Information” window shown next, ensure that the check box that says “Use controllers…” is checked, as we’ll be using controllers instead of minimal APIs in this example. Leave the “Authentication Type” set to “None” (default).
9. Ensure that the check boxes “Enable Docker,” “Configure for HTTPS,” and “Enable Open API Support” are unchecked as we won’t be using any of those features here.
10. Click Create.

We’ll use this ASP.NET Core 6 Web API project to illustrate migrations of ASP.NET Core 5 code to ASP.NET Core 6 in the subsequent sections of this article.
