Chapter 4. Publishing applications with .NET Core 3.1


.NET Core 3.1 applications can be published to use a shared system-wide version of .NET Core or to include .NET Core.

The following methods exist for publishing .NET Core 3.1 applications:

  • Framework-dependent deployment (FDD) - The application uses a shared system-wide version of .NET.
Note

When publishing an application for RHEL, Red Hat recommends using FDD, because it ensures that the application is using an up-to-date version of .NET Core, built by Red Hat, that uses a set of native dependencies.

  • Self-contained deployment (SCD) - The application includes .NET. This method uses a runtime built by Microsoft.

Prerequisites

  • Existing .NET Core application.

    For more information on how to create a .NET Core application, see

4.1. Publishing .NET Core applications

The following procedure outlines how to publish a framework-dependent application.

Procedure

  1. Publish the framework-dependent application:

    $ dotnet publish my-app -f netcoreapp3.1 -c Release
    Copy to Clipboard Toggle word wrap

    Replace my-app with the name of the application you want to publish.

  2. Optional: If the application is for RHEL only, trim out the dependencies needed for other platforms:

    $ dotnet restore my-app -r rhel.9-x64
    $ dotnet publish my-app -f netcoreapp3.1 -c Release -r rhel.9-x64 --self-contained false
    Copy to Clipboard Toggle word wrap
    Note

    If you are using an arm64/aarch64 machine, use:

    $ dotnet restore my-app -r rhel.9-arm64
    $ dotnet publish my-app -f netcoreapp3.1 -c Release -r rhel.9-arm64 --self-contained false
    Copy to Clipboard Toggle word wrap
