Single File Generator Sample

Create a Single File Generator that uses an XML source file to generate a new C# file in Visual Studio.

  • Technologies: Visual Studio 2015 SDK
  • Topics: Visual Studio Shell, MSDBuild, VSX

Description

A single file generator pulls information from a source file and generates a new file from the data. This sample single file generator uses an XML Schema to pull data from an XML file and generate a C# file. The generator leverages CodeDom to generate C# source code. It also demonstrates how to validate an XML document against a schema and communicate errors through the Error List.

Requirements

Visual Studio 2015

Get all samples

Clone the repo (How to):

git clone https://github.com/Microsoft/VSSDK-Extensibility-Samples.git

Run the sample

  1. To run the sample, hit F5 or choose the Debug > Start Debugging menu command. A new experimental instance of Visual Studio will launch.
  2. Once loaded, create a new project. Ex:_ WpfApplication_
  3. Add a new XML file to the project. File > Add > New File
  4. Populate the new XML file with content using the schema from XmlClassGeneratorSchema.xsd. For a working example, Copy/Paste the code from Example.XmlFile.xml into your new XML file.
  5. Open the Properties window for the xml file and set CustomTool to XmlClassGenerator.
  6. Save the XML file. This triggers the single file generator to run and generate a new C# file.
  7. The new C# file is added to the project with the same name as the XML file. This new file appears in Solution Explorer as a dependent of the original XML file node.
  8. Any errors will be reported in the Error List toolwindow.

Project Files

  • AssemblyInfo.cs

This file contains assembly custom attributes.

  • BaseCodeGenerator.cs

Abstract class that implements the IVsSingleFileGenerator interface.

  • BaseCodeGeneratorWithSite.cs

Abstract class that inherits from BaseCodeGenerator and implements the IObjectWithSite interface.

  • XmlClassGenerator.cs

The single file generator class.

  • SourceCodeGenerator.cs

Static class that contains the CodeDom code used to generate source code.

  • XmlClassGeneratorSchema.xsd

XML Schema document tells the generator how to convert source code.

  • Strings.resx

Resource strings (localizable).

Functional Tests

  • Verify the sample builds in Debug Configuration
  • Verify the sample builds in Release Configuration
  • Verify that the generator is properly registered when building
  • Verify that the generator works
  • Verify that the generator fails for bad XML
