.NET Core Generator Requirements

Official Content
This documentation is valid for:


To build .NET Core applications, you need to install .NET Core SDK 3.1.x, which is available here: .NET Core SDK 3.1.x (LTS).

If .NET Core SDK is not installed, the following error will be displayed: "error: Dotnet.exe doesn't exist. Install .NET Core SDK."
After installing the SDK, it is necessary to close GeneXus and open it again.

Optional: Run .NET Core applications using IIS

By default, the .NET Core generator runs web applications in the Kestrel web server that is included in .NET Core SDK. To run the application with IIS working as a reverse proxy in front of Kestrel, install ASP.NET Core Runtime 3.1.x Hosting Bundle.

Remember to set the generator Web Server property to "Internet Information Server."


This article is valid for GeneXus 16 upgrade 8 or higher. For previous versions, read .Net Core Generator Requirements (GeneXus 16 Upgrade 7 or prior).
