AssemblyInfo.AssemblyInfoFiles Property

Use the AssemblyInfoFile property to provide the task with the list of AssemblyInfo files that should be updated by the task. This can be a mix of VB, C# and J# AssemblyInfo Files.

When using the MSBuild.ExtensionPack.VersionNumber.Targets file add items to the AssemblyInfoFiles item group to have them processed by the task.

<!-- Add all AssemblyInfo files in all sub-directories to the list of
files that should be processed by the task -->
<ItemGroup>
    <AssemblyInfoFiles>**\AssemblyInfo.*</AssemblyInfoFiles>
</ItemGroup>
