ClickOnce for .NET on Windows

  • Article

This article describes the differences between ClickOnce for .NET Core 3.1, .NET 5, and later, versus ClickOnce for .NET Framework.

Publish tool

Starting in Visual Studio 2019, ClickOnce for .NET Core 3.1 and .NET 5 or later uses the Publish tool instead of the Publish Wizard and properties pages. The Publish tool creates a .pubxml file, called a publish profile. Most of the properties previously available in the wizard are available to configure in the Publish tool. For detailed instructions, see Deploy a .NET Windows application using ClickOnce.

MSBUILD

For building from the command line using MSBUILD, you need to specify the .pubxml file. For more information, see Build .NET ClickOnce applications from the command line.

ApplicationDeployment class

In .NET Core 3.1, .NET 5, and .NET 6, you don't have programmatic access to the ApplicationDeployment class or to other APIs in the System.Deployment.Application namespace.

Starting in .NET 7, you can access properties in the ApplicationDeployment class using environment variables. For more information, see Access ClickOnce deployment properties in .NET.

Mage.exe

In .NET Core 3.1 and .NET 5 and later, use dotnet-mage.exe instead of Mage.exe to create the ClickOnce deployment.

You can install dotnet-mage.exe using the NuGet package.

To access activation data using dotnet-mage.exe, see Access ClickOnce activation data for .NET.
