UpackLib.NET

This library is a work-in-progress set of utilities for working with Universal Packages and feeds.

Installation

Add a reference to Inedo.UPack using NuGet package manager.

Creating a Package

Use the UniversalPackageBuilder class to create a new .upack file:

var metadata = new UniversalPackageMetadata
{
    Group = "my/group",
    Name = "MyPackage",
    Version = UniversalPackageVersion.Parse("1.0.0"),
    Title = "My Test Package",
    Description = "This is where a useful description would go.",
    ["_customProperty"] = "I am a custom, extended property."
};

using (var builder = new UniversalPackageBuilder("MyPackage.upack", metadata))
{
    // Recursively add all files and directories from C:\Test\MyFiles to the package
    await builder.AddContentsAsync(@"C:\Test\MyFiles", "", true);
}

Opening a Package

Create an instance of the UniversalPackage class:

using (var package = new UniversalPackage("MyPackage.upack"))
{
}

Read Package Metadata

Access the properties on a UniversalPackage instance:

Console.WriteLine($"Package name: {package.Name}");
Console.WriteLine($"Package version: {package.Version}");

// The UniversalPackage class only provides basic metadata.
// To get a copy of all metadata, call the GetFullMetadata method.
var fullMetadata = package.GetFullMetadata();
Console.WriteLine($"Package title: {fullMetadata.Title}");

Extract Package Contents

Use the ExtractContentItemsAsync method on a UniversalPackage instance:

await package.ExtractContentItemsAsync(@"C:\Test\UnpackedPackage");

Opening the Package Registry

Use the GetRegistry method on the PackageRegistry class:

using (var registry = PackageRegistry.GetRegistry(true /*true for user registry*/))
{
}

Registering a Package

Lock the package registry and call the RegisterPackageAsync method on a PackageRegistry instance:

await registry.LockAsync();
await registry.RegisterPackageAsync(
    new RegisteredPackage
    {
        Group = "my/group",
        Name = "MyPackage",
        Version = "1.0.0",
        InstallPath = @"C:\Test\UnpackedPackage",
        InstallationDate = DateTimeOffset.Now.ToString("o"),
        InstallationReason = "No reason - just a test!",
        InstalledUsing = "My upack client",
        InstalledBy = "Steve"
    }
);

Getting a List of Registered Packages

Call the GetInstalledPackagesAsync method on a PackageRegistry instance:

foreach (var p in await registry.GetInstalledPackagesAsync())
    Console.WriteLine($"{p.Name} {p.Version}");

Connecting to a Universal Package Feed

Create a new instance of the UniversalFeedClient class:

var feed = new UniversalFeedClient("http://upack.example.com/feed");

List Feed Packages in a Group

Call ListPackagesAsync on a UniversalFeedClient instance:

var packages = await feed.ListPackagesAsync("my/group", null);

Download a Feed Package to a File

Call GetPackageStreamAsync on a UniversalFeedClient instance to get a stream:

using (var packageStream = await feed.GetPackageStreamAsync(UniversalPackageId.Parse("my/group/MyPackage"), UniversalPackageVersion.Parse("1.0.0")))
using (var fileStream = File.Create(@"C:\Test\DownloadedPackage.upack"))
{
    await packageStream.CopyToAsync(fileStream);
}

Upload a Package to a Feed

Call UploadPackageAsync on a UniversalFeedClient instance:

using (var fileStream = File.OpenRead(@"C:\Test\SourcePackage.upack"))
{
    await feed.UploadPackageAsync(fileStream);
}
