How to Use the Language for MPS Programs

Please follow these instruction in this order:

Prerequisites

Install the following plugins:
- LangDoc
- TextGenGen

Generating TextGen

Right-click the language item in the project explorer
Trigger Generate TextGen

Building the plugin

Right-click the language item in the project explorer and select Rebuild Language CsBaseLanguage
Then, right-click the whole project in the project explorer and rebuild it as well (we could not have rebuilt it whole in the first place because of errors of not having the language built before)
Expand the CsBaseLanguage.build item in the project explorer
Right-click the CsBaseLanguage item with a spider icon
Trigger the option Run CsBaseLanguage
The plugin ZIP file is located in the directory hierarchy of the project (go to build/artifacts/CsBaseLanguage)

Plugin Instalation

Go to File > Settings > Plugins > the Sprocket icon (top right part of the window) > Install Plugin from Disk
Locate the plugin ZIP file
Click on the OK button
Restart your MPS

Usage

Create a new Solution project
Create a new model
Right-click your model and select Model Properties
Under the tab Used languages, add a dependency on the C# base language
- Use the plus button on the right
- Type in CsBaseLanguage
- Select the corresponding item
Now you can use the root concept File after right-clicking your model and selecting Add

C# Standard Library

If you want to use the C# standard library:

Install it as separate plugin called CsStdLibrary
Put the models corresponding to C# standard library namespaces (e.g. System, System.Collections) into the dependencies of your model
