This article show how to upgrade an ASP.NET Framework MVC app to ASP.NET Core MVC using the Visual Studio [.NET Upgrade Assistant](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.upgradeassistant) and the [incremental update](xref:migration/inc/overview) approach.
## Upgrade using the .NET Upgrade Assistant
If your .NET Framework project has supporting libraries in it's solution that are required, they should be upgraded to .NET Standard 2.0, if possible. For more information, see [Upgrade supporting libraries](/aspnet/core/migration/inc/start#upgrade-supporting-libraries).
1. Install the [.NET Upgrade Assistant](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.upgradeassistant) Visual Studio extension.
1. Open the ASP.NET MVC solution in Visual Studio.
1. In **Solution Explorer**, right click on the project to upgrade and select **Upgrade**. Select **Side-by-side incremental project upgrade**, which is the only upgrade option.
1. For the upgrade target, select **New project**.
1. Name the project and select the template. If the project you're migrating is a API project, select **ASP.NET Core Web API**. If it's an MVC project or MVC and Web API, select **ASP.NET Core MVC**.
1. Select the target framework version and then select **Next**. For more information, see [.NET and .NET Core Support Policy](https://dotnet.microsoft.com/platform/support/policy/dotnet-core).
1. On the **Summary of changes** step, select **Finish**.
1. The **Summary** step displays **`<Framework Project>` is now connected to `<Framework ProjectCore>` via Yarp proxy.** and a pie chart showing the migrated endpoints. Select **Upgrade Controller** and then select a controller to upgrade.
1. Select the component to upgrade, then select **Upgrade selection**.
