How to specify what plugins are required for the project. Prompt developers in a team to install these plugins

Situation

When a project is opened on a freshly installed Rider, and working on that project requires specific plugins to be installed, it might be not clear what plugins need to be installed

Question

How to let other developers in the team know what plugins need to be installed and let them quickly install the necessary those.

Answer

It can be done by sharing the .idea/externalDependencies.xml file through the VCS. The file represents the settings set in Settings | Build, Execution, Deployment | Required Plugins:

• Go to Settings | Build, Execution, Deployment | Required Plugins;
• Add the needed plugins to the list;
• Save the settings;
• Commit the <SolutionFolder>/.idea/externalDependencies.xml file to the VCS;

When another user pulls this change and open this project in Rider, one will be prompted to install missing plugins:
