How can I write Nuspec for MEF Plugin File - mef

Question

I want to write nuspec for MEF plugin.
I can copy xxx.dll to content directory, like below.
<files>
<file src="Alhambra\bin\Release\Plugins\Alhambra.Plugin.SqlServer.dll" target="content\Plugins\Alhambra.Plugin.SqlServer.dll" />
<file src="Alhambra\bin\Release\Alhambra.dll" target="lib\Alhambra.dll" />
</files>
but I can't set file property in user project to copy output directory.
Thanks for any suggestions or code snippets.

My approach would be to add the plugin to the project as a separate file. For that you need an install script (see NuGet docs for this).
My solution for this is the following script:
param($installPath, $toolsPath, $package, $project)
Function add_file($file)
{
$do_add = 1
foreach($item in $project.DTE.ActiveSolutionProjects[0].ProjectItems)
{
if ($item -eq $file)
{ $do_add = 0 }
}
if ($do_add -eq 1)
{
$added = $project.DTE.ItemOperations.AddExistingItem($file)
$added.Properties.Item("CopyToOutputDirectory").Value = 2
$added.Properties.Item("BuildAction").Value = 0
}
}
add_file(<file1>)
add_file(<file2>)
Of course, when the user uninstalls the package, you need to clean up:
param($installPath, $toolsPath, $package, $project)
Function remove_file($file)
{
foreach($item in $project.DTE.ActiveSolutionProjects[0].ProjectItems)
{
if ($item.Name -eq $file)
{
$item.Delete()
}
}
}
remove_file(<file1>)
remove_file(<file2>)
