The Domain-Specific Designer Wizard provides the following solution templates:

• Task Flow

• Class Diagrams

• Minimal Language

• Component Models

For more information, see Choosing a Domain-Specific Language Solution Template.

The wizard creates a Visual Studio solution that has the following projects:

• Dsl

  The Dsl project defines the domain-specific language and its editing and processing tools.

• DslPackage

  The DslPackage project determines how the language tools integrate with Visual Studio.

You can use the DSL Tools graphical interface to add elements and relationships to your domain-specific language. After you have added the elements, you can define their appearance by mapping them to shapes, customizing colors, and adding decorators. You can also add the elements to the toolbox.

Dsl provides one level of validation to make sure that the domain model meets the basic requirements for code generation. Typically, when you create your own domain-specific language, you would add your own validation to express your business logic rules. For more information about custom validation, see Adding Validation to Domain-Specific Language Solutions.

We recommend that you validate your domain-specific language often when you are designing it. If your domain-specific language has validation errors, you cannot generate source code. The process of generating source code from the templates is called transformation. Whenever you modify the language definition, also make sure to modify the templates. For more information, see Walkthrough: Creating a Domain-Specific Language Solution.

You can provide additional code to refine the behavior of the model and to define constraints over your language. If required, you can make significant changes by modifying the text templates.

DSL Tools generates a package that is hosted in Visual Studio. The package displays a toolbox, a DSL explorer, and other UI elements that let users create models by using your domain-specific language.

When you build and run the DSL Tools solution in Visual Studio, a second instance of Visual Studio shows you how your domain-specific language looks to the user of the language. After you verify that everything works correctly, you can create a deployment package to distribute your domain-specific language. For more information, see Deploying Domain-Specific Language Solutions.
