Registering a license

When you use Metalama for the first time, the license registration UI will open, where you can choose between the 45-day evaluation mode, the Metalama Free, or registering a license key.

To change your license after the activation UI has closed, you can choose one of the following approaches.

With the Visual Studio tooling

You can manage your Metalama licenses using Visual Studio Tools for Metalama and PostSharp. For instructions on how to install it, see Installing Visual Studio Tools for Metalama and PostSharp.

To access these options:

1. In the top-level menu, choose Extensions > Metalama + PostSharp > Options.
2. Go to the License tab.

With the command-line tool

You can manage licensing options using the metalama CLI tool.

First, install the Metalama Command Line Tools as detailed in Installing the Metalama Command Line Tool.

The following commands are available:

By editing the configuration file

To manually register a license for the current user, do the following:

1. Open the Metalama licensing JSON configuration file licensing.json. This file is located in the %appdata%\\.metalama directory on Windows, and in the ~/.metalama directory on Linux and Mac.

2. Set the license key as the license value. If the file doesn't exist, it should contain the following content (where 123-ABCDEFGHIJKLMNOPQRSTUVXYZ is a placeholder for the actual license key):

   {
     "license": "123-ABCDEFGHIJKLMNOPQRSTUVXYZ"
   }
   

With an environment variable or MSBuild property

The license key can be stored as the value of the MetalamaLicense MSBuild property. This allows for the following:

• Storing the license as a value of the MetalamaLicense environment variable.
• Storing the license in the source code repository using the Directory.Build.props file.
• Storing the license in the .csproj project file.
