Generate launch.json from the Web Client in Business Central – Wave 1 2025

With the 2025 Wave 1 release of Microsoft Dynamics 365 Business Central, developers get a significant productivity boost: the ability to generate a launch.json file directly from the Web Client! This is a feature that eliminates the need to manually configure environment settings in Visual Studio Code (VS Code), especially useful when working across multiple environments or containers.

What is launch.json?

In AL development for Business Central, the launch.json file defines how your AL project connects to your Business Central environment. It includes settings like:

{
  "name": "Your Environment",
  "type": "al",
  "request": "launch",
  "server": "https://your-environment-url",
  "serverInstance": "BC",
  "authentication": "UserPassword",
  "tenant": "your-tenant-id"
}

You can now generate the launch.json configuration directly from the Web Client using just a few clicks. No more copying URLs, figuring out authentication types, or guessing server details.

Steps to Generate:

1. Log into your Business Central Web Client.
2. Navigate to the Help & Support page (? page=134).
3. Scroll down to the Troubleshooting section.
4. Look for the new Download launch.json button (or similar option).
5. Click it – a launch.json file will be downloaded, pre-filled with your current environment’s configuration.

Second option will be navigate Installed extensions and download launch.json

The introduction of the launch.json generation feature in the Business Central Wave 1 2025 web client is a welcome addition for AL developers. It promises to streamline the initial setup process, reduce configuration errors, and enhance overall development efficiency.
