    <!--
      The task calculates SourceLink URL for a given SourceRoot.

      If the SourceRoot is associated with a git repository with a recognized host the <see cref="SourceLinkUrl"/>
      output property is set to the content URL corresponding to the domain, otherwise it is set to string "N/A".

      Recognized hosts are specified via Hosts parameter (initialized from SourceLinkAzureDevOpsServerHost item group).
      Host specification includes the host domain, a port (optional) and virtual directory (optional).

      Since the virtual directory of a Azure DevOps Server can't be inferred from the repository URL, at least one host has to be specified.

      Example of SourceLinkAzureDevOpsServerGitHost items:

      <ItemGroup>
        <SourceLinkAzureDevOpsServerGitHost Include="mytfs1.com/tfs" ContentUrl="http://mytfs1.com"/>
        <SourceLinkAzureDevOpsServerGitHost Include="mytfs2.com/tfs" />           ContentUrl defaults to https://mytfs2.com
        <SourceLinkAzureDevOpsServerGitHost Include="mytfs3.com:8080/tfs" />      ContentUrl defaults to https://mytfs3.com:8080
      </ItemGroup>

      ContentUrl is optional. If not specified it defaults to "https://{domain}" or "http://{domain}", based on the scheme of SourceRoot.RepositoryUrl.
   
      In common cases ContentUrl does not include the virtual directory. 
      The directory is appended to the ContentUrl automatically when the SourceLink URL is constructed.
