A MSBuild task to convert XML documentation to Markdown syntax. Support both .Net Framework and .Net Core projects.

• Provide full information from the XML documentation file.
• Provide easy reading facilities - parameter table, link tooltip, etc.
• Provide table of contents to type and member links.
• Highlight code block through <code lang="csharp"> tag.
• Reference System types to official MSDN pages.

If you are using Visual Studio:

• In Visual Studio, right click project name to open project properties window.
• Switch to Build tab, in Output section, check XML documentation file checkbox.
• Install Vsxmd package from NuGet.
• Build the project, then a markdown file is generated next to the XML documentation file.

If you are using .Net Core CLI:

• Open project's CSPROJ file, declare DocumentationFile property in PropertyGroup section. The path is relative to the project directory. MSBuild Reserved and Well-Known properties are also available for this property.
• Run dotnet add package Vsxmd to install the the package to the project.
• Run dotnet build to build the project and generate the XML documentation and Markdown files.

There are some properties to customize the Markdown file generation process. They are all optional. If you want to use them, declare them in CSPROJ file's PropertyGroup section.

It is used to specify the generated Markdown file path. It defaults to the XML documentation file name with .md extension, under the same folder as the XML file. Similar to DocumentationFile property, the path is relative to the project directory and MSBuild properties are available.

<PropertyGroup>
    <DocumentationMarkdown>$(MSBuildProjectDirectory)\API.md</DocumentationMarkdown>
</PropertyGroup>

A boolean flag to delete the XML documentation file after the Markdown file is generated.

<PropertyGroup>
    <VsxmdAutoDeleteXml>True</VsxmdAutoDeleteXml>
</PropertyGroup>

There are some extended features based on XML documentation. They are not described in XML recommended tags, but they are worth to use.

To highlight code block in the Markdown file, declare the attribute lang in <code> tag and set it to a program language identifier.

<code lang="javascript">
    function test() {
        console.log("notice the blank line before this function?");
    }
</code>

This library provides the following programmatic API to convert XML documentation file to Markdown syntax programmatically.

• Converter : IConverter
  • string ToMarkdown()
  • static string ToMarkdown(XDocument document)

The best demo is this project's documentation file, Vsxmd.md. It is generated by this project itself.

The syntax for the list comment tag is not well defined. It will be skipped during render. If you have ideas, please open an issue.

This project is initially inspired from a gist. But in the later releases, the implementation is rewritten.
