How to generate documentation for other projects within solution using DocFx - documentation-generation

Question

I am using DocFx to automatically generate documentation in Visual Studio 2015.
Per the Getting Started instructions, I added an empty ASP.NET 4 Web Application and used the Nuget Console to install the DocFx build package (e.g. Install-Package docfx.msbuild). I built the site and it it generated documentation for code within the project.
I was wondering how to configure docfx.json to get DocFx to document code in other projects within the solution.

Answer 1

In docfx.json, there is an array of metadata. The example metadata has a src object with files and exclude properties.
To point to another project in your solution, add a cwd property to metadata and change folders (i.e. "../Another.Project").
{
"metadata": [
{
"src": [
{
"files": [ "**/*.csproj" ],
"exclude": [ "**/bin/**", "**/obj/**", "_site/**" ],
"cwd": "../Another.Project"
}
],
"dest": "obj/api"
}
],
"build": ...
}

Answer 2

This worked for me.
directory structure
+---ClassLibrary
| \---ClassLibrary.csproj
\---DocFxProject
\---docfx.json
docfx.json contents
cwd and src are synonyms for the same property
{
"metadata":
[
{
"src":
[
{
"files": [ "**/ClassLibrary.csproj" ],
"src": "..",
"exclude": [ "**/obj/**", "**/bin/**" ]
}
],
"dest": "obj/api"
}
],
"build": { ... }
}
