How to include Swashbuckle .xml files in your Service Fabric project

If you’re using Swashbuckle’s IncludeXmlComments() option, then your build needs to output an XML file containing the various comments.

By default, the XML file will not be included in your Service Fabric deployment. To get it to work, one way is to add the following section to your Web project’s .csproj:

  <Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
    <ItemGroup>
      <DocFile Include="bin\x64\$(Configuration)\$(TargetFramework)\win7-x64\*.xml" />
    </ItemGroup>
    <Copy SourceFiles="@(DocFile)" DestinationFolder="$(PublishDir)" SkipUnchangedFiles="false" />
  </Target>

You should also make sure that your xml file is output for all of these different build configurations, again in your Web project’s .csproj:

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <DocumentationFile>bin\Debug\net46\win7-x64\WebHost.xml</DocumentationFile>
    <NoWarn>1701;1702;1705;1591</NoWarn>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">
    <DocumentationFile>bin\Debug\net46\win7-x64\WebHost.xml</DocumentationFile>
    <NoWarn>1701;1702;1705;1591</NoWarn>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <DocumentationFile>bin\Release\net46\win7-x64\WebHost.xml</DocumentationFile>
    <NoWarn>1701;1702;1705;1591</NoWarn>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|x64'">
    <DocumentationFile>bin\Release\net46\win7-x64\WebHost.xml</DocumentationFile>
    <NoWarn>1701;1702;1705;1591</NoWarn>
  </PropertyGroup>
