Adding extra files for MSBuild Deployment
Adding extra files/folders for a MSBuild Deployment that aren't referenced by your project file can be done by adding a target. In this case it is named CustomCollectFiles
MyProject.csproj
<Target Name="CustomCollectFiles">
<Message Text="Collecting extra files" />
<ItemGroup>
<_CustomFiles Include="assets\js\**\*" />
<FilesForPackagingFromProject Include="%(_CustomFiles.Identity)">
<DestinationRelativePath>assets\js\%(RecursiveDir)%(Filename)%(Extension)</DestinationRelativePath>
</FilesForPackagingFromProject>
</ItemGroup>
<Message Text="Finish collecting extra files" />
</Target>
<PropertyGroup>
<CopyAllFilesToSingleFolderForPackageDependsOn>
CustomCollectFiles;
$(CopyAllFilesToSingleFolderForPackageDependsOn);
</CopyAllFilesToSingleFolderForPackageDependsOn>
<CopyAllFilesToSingleFolderForMsdeployDependsOn>
CustomCollectFiles;
$(CopyAllFilesToSingleFolderForMsdeployDependsOn);
</CopyAllFilesToSingleFolderForMsdeployDependsOn>
</PropertyGroup>
