Overview

PackageCatalog represents a searchable package source. Before using a catalog, you must first obtain a PackageCatalogReference and connect to it. Once connected, you can search for packages using various filters.

​
Class Definitions

​
PackageCatalogReference

runtimeclass PackageCatalogReference
{
    Boolean IsComposite { get; };
    PackageCatalogInfo Info { get; };
    
    IAsyncOperation<ConnectResult> ConnectAsync();
    ConnectResult Connect();
    
    String AdditionalPackageCatalogArguments;
    IVectorView<SourceAgreement> SourceAgreements { get; };
    Boolean AcceptSourceAgreements;
    TimeSpan PackageCatalogBackgroundUpdateInterval;
    Boolean InstalledPackageInformationOnly;
    AuthenticationArguments AuthenticationArguments;
    AuthenticationInfo AuthenticationInfo { get; };
    
    IAsyncOperationWithProgress<RefreshPackageCatalogResult, Double> 
        RefreshPackageCatalogAsync();
}

​
PackageCatalog

runtimeclass PackageCatalog
{
    Boolean IsComposite { get; };
    PackageCatalogInfo Info { get; };
    
    IAsyncOperation<FindPackagesResult> FindPackagesAsync(FindPackagesOptions options);
    FindPackagesResult FindPackages(FindPackagesOptions options);
}

​
PackageCatalogInfo

runtimeclass PackageCatalogInfo
{
    String Id { get; };
    String Name { get; };
    String Type { get; };
    String Argument { get; };
    DateTime LastUpdateTime { get; };
    PackageCatalogOrigin Origin { get; };
    PackageCatalogTrustLevel TrustLevel { get; };
    Boolean Explicit { get; };
    Int32 Priority { get; };
}

​
Connecting to a Catalog

​
Basic Connection

var manager = new PackageManager();
var catalogRef = manager.GetPredefinedPackageCatalog(
    PredefinedPackageCatalog.OpenWindowsCatalog
);

// Connect to catalog
var connectResult = await catalogRef.ConnectAsync();

if (connectResult.Status == ConnectResultStatus.Ok)
{
    var catalog = connectResult.PackageCatalog;
    Console.WriteLine("Connected to catalog");
    
    // Now you can search
}
else
{
    Console.WriteLine($"Connection failed: {connectResult.Status}");
    Console.WriteLine($"Error: 0x{connectResult.ExtendedErrorCode:X}");
}

​
Connection with Agreement Acceptance

Some catalogs require accepting source agreements: 
var catalogRef = manager.GetPackageCatalogByName("customsource");

// Check for required agreements
var agreements = catalogRef.SourceAgreements;
if (agreements.Count > 0)
{
    Console.WriteLine("Source requires acceptance of agreements:");
    foreach (var agreement in agreements)
    {
        Console.WriteLine($"- {agreement.Label}");
        Console.WriteLine($"  {agreement.Text}");
        Console.WriteLine($"  URL: {agreement.Url}");
    }
    
    // Accept agreements
    catalogRef.AcceptSourceAgreements = true;
}

var connectResult = await catalogRef.ConnectAsync();

​
Authentication

For catalogs requiring authentication: 
var catalogRef = manager.GetPackageCatalogByName("privatecatalog");

// Check authentication requirements
var authInfo = catalogRef.AuthenticationInfo;
if (authInfo != null && authInfo.AuthenticationType == AuthenticationType.MicrosoftEntraId)
{
    // Set up authentication
    var authArgs = new AuthenticationArguments()
    {
        AuthenticationMode = AuthenticationMode.SilentPreferred,
        AuthenticationAccount = "[email protected]"
    };
    catalogRef.AuthenticationArguments = authArgs;
}

var connectResult = await catalogRef.ConnectAsync();

​
Searching for Packages

​
FindPackagesOptions

runtimeclass FindPackagesOptions
{
    FindPackagesOptions();
    
    IVector<PackageMatchFilter> Selectors { get; };
    IVector<PackageMatchFilter> Filters { get; };
    UInt32 ResultLimit;
}
Search Logic:
  • Selectors - You must match at least ONE selector (OR logic)
  • Filters - You must match ALL filters (AND logic)
  • Final result = (Selector1 OR Selector2 OR ...) AND Filter1 AND Filter2 AND ...

​
PackageMatchFilter

​
Field
PackageMatchField
required
The field to search
​
Value
String
required
The value to match
​
Option
PackageFieldMatchOption
required
How to match the value
PackageMatchField values:
  • CatalogDefault - Default search across all fields
  • Id - Package identifier
  • Name - Package name
  • Moniker - Package moniker (short name)
  • Command - Executable command
  • Tag - Package tags
  • PackageFamilyName - Package family name
  • ProductCode - Product code
PackageFieldMatchOption values:
  • Equals - Case-sensitive exact match
  • EqualsCaseInsensitive - Case-insensitive exact match
  • StartsWithCaseInsensitive - Case-insensitive prefix match
  • ContainsCaseInsensitive - Case-insensitive substring match
var options = new FindPackagesOptions();

// Search by package ID
var filter = new PackageMatchFilter()
{
    Field = PackageMatchField.Id,
    Value = "Microsoft.PowerToys",
    Option = PackageFieldMatchOption.Equals
};
options.Selectors.Add(filter);

var result = await catalog.FindPackagesAsync(options);

if (result.Status == FindPackagesResultStatus.Ok)
{
    Console.WriteLine($"Found {result.Matches.Count} packages");
    
    foreach (var match in result.Matches)
    {
        var package = match.CatalogPackage;
        Console.WriteLine($"ID: {package.Id}");
        Console.WriteLine($"Name: {package.Name}");
        Console.WriteLine($"Version: {package.DefaultInstallVersion.Version}");
    }
    
    if (result.WasLimitExceeded)
    {
        Console.WriteLine("Results were truncated");
    }
}

​
Search by Name (Partial Match)

var options = new FindPackagesOptions();

// Search for packages containing "visual studio"
var filter = new PackageMatchFilter()
{
    Field = PackageMatchField.Name,
    Value = "visual studio",
    Option = PackageFieldMatchOption.ContainsCaseInsensitive
};
options.Selectors.Add(filter);

// Limit results
options.ResultLimit = 10;

var result = await catalog.FindPackagesAsync(options);

​
Multiple Selectors (OR Logic)

var options = new FindPackagesOptions();

// Find by ID OR moniker
options.Selectors.Add(new PackageMatchFilter()
{
    Field = PackageMatchField.Id,
    Value = "Microsoft.VisualStudioCode",
    Option = PackageFieldMatchOption.Equals
});

options.Selectors.Add(new PackageMatchFilter()
{
    Field = PackageMatchField.Moniker,
    Value = "vscode",
    Option = PackageFieldMatchOption.EqualsCaseInsensitive
});

// This will find packages matching EITHER selector
var result = await catalog.FindPackagesAsync(options);

​
Using Filters (AND Logic)

var options = new FindPackagesOptions();

// Selector: search for packages with "microsoft" in name
options.Selectors.Add(new PackageMatchFilter()
{
    Field = PackageMatchField.Name,
    Value = "microsoft",
    Option = PackageFieldMatchOption.ContainsCaseInsensitive
});

// Filter: only packages with specific tag
options.Filters.Add(new PackageMatchFilter()
{
    Field = PackageMatchField.Tag,
    Value = "developer-tools",
    Option = PackageFieldMatchOption.Equals
});

// This finds packages with "microsoft" in name AND tag "developer-tools"
var result = await catalog.FindPackagesAsync(options);

​
Search All Packages

// Empty options returns all packages (up to ResultLimit)
var options = new FindPackagesOptions()
{
    ResultLimit = 100 // Limit to 100 packages
};

var result = await catalog.FindPackagesAsync(options);

Console.WriteLine($"Total packages: {result.Matches.Count}");
if (result.WasLimitExceeded)
{
    Console.WriteLine("More packages available, but limited to 100");
}

​
Working with Results

​
FindPackagesResult

runtimeclass FindPackagesResult
{
    FindPackagesResultStatus Status { get; };
    IVectorView<MatchResult> Matches { get; };
    Boolean WasLimitExceeded { get; };
    HRESULT ExtendedErrorCode { get; };
}
FindPackagesResultStatus values:
  • Ok - Search successful
  • BlockedByPolicy - Blocked by group policy
  • CatalogError - Catalog error occurred
  • InternalError - Internal error
  • InvalidOptions - Invalid search options
  • AuthenticationError - Authentication failed
  • AccessDenied - Access denied to catalog

​
MatchResult

runtimeclass MatchResult
{
    CatalogPackage CatalogPackage { get; };
    PackageMatchFilter MatchCriteria { get; };
}

foreach (var match in findResult.Matches)
{
    var package = match.CatalogPackage;
    var criteria = match.MatchCriteria;
    
    Console.WriteLine($"Package: {package.Name}");
    Console.WriteLine($"Matched on: {criteria.Field} = {criteria.Value}");
    
    // Access package details
    if (package.DefaultInstallVersion != null)
    {
        var version = package.DefaultInstallVersion;
        Console.WriteLine($"Version: {version.Version}");
        Console.WriteLine($"Publisher: {version.Publisher}");
        Console.WriteLine($"Display Name: {version.DisplayName}");
    }
    
    // Check if update available
    if (package.IsUpdateAvailable)
    {
        Console.WriteLine("Update available!");
    }
}

​
CatalogPackage

runtimeclass CatalogPackage
{
    String Id { get; };
    String Name { get; };
    PackageVersionInfo InstalledVersion { get; };
    IVectorView<PackageVersionId> AvailableVersions { get; };
    PackageVersionInfo DefaultInstallVersion { get; };
    PackageVersionInfo GetPackageVersionInfo(PackageVersionId versionKey);
    Boolean IsUpdateAvailable { get; };
    
    IAsyncOperation<CheckInstalledStatusResult> CheckInstalledStatusAsync(InstalledStatusType checkTypes);
    CheckInstalledStatusResult CheckInstalledStatus(InstalledStatusType checkTypes);
    
    IReference<Int32> CatalogPriority { get; };
}

​
Getting Package Metadata

var package = match.CatalogPackage;
var version = package.DefaultInstallVersion;

// Get catalog metadata (requires contract v6+)
var metadata = version.GetCatalogPackageMetadata();

Console.WriteLine($"Publisher: {metadata.Publisher}");
Console.WriteLine($"License: {metadata.License}");
Console.WriteLine($"Description: {metadata.Description}");
Console.WriteLine($"Package URL: {metadata.PackageUrl}");
Console.WriteLine($"Publisher URL: {metadata.PublisherUrl}");

// Tags
if (metadata.Tags.Count > 0)
{
    Console.WriteLine("Tags: " + string.Join(", ", metadata.Tags));
}

// Icons
foreach (var icon in metadata.Icons)
{
    Console.WriteLine($"Icon: {icon.Url} ({icon.Resolution}, {icon.Theme})");
}

// Agreements
foreach (var agreement in metadata.Agreements)
{
    Console.WriteLine($"Agreement: {agreement.Label}");
    Console.WriteLine($"  {agreement.Text}");
    Console.WriteLine($"  URL: {agreement.Url}");
}

​
Getting Specific Version

var package = match.CatalogPackage;

// List all available versions
foreach (var versionId in package.AvailableVersions)
{
    Console.WriteLine($"Available: {versionId.Version} (Channel: {versionId.Channel})");
}

// Get specific version
if (package.AvailableVersions.Count > 0)
{
    var versionKey = package.AvailableVersions[0];
    var versionInfo = package.GetPackageVersionInfo(versionKey);
    
    Console.WriteLine($"Version: {versionInfo.Version}");
    Console.WriteLine($"Display Name: {versionInfo.DisplayName}");
    Console.WriteLine($"Publisher: {versionInfo.Publisher}");
}

​
Composite Catalogs

Composite catalogs combine multiple sources for unified searching: 
var manager = new PackageManager();

var options = new CreateCompositePackageCatalogOptions();

// Add catalogs to composite
options.Catalogs.Add(
    manager.GetPredefinedPackageCatalog(PredefinedPackageCatalog.OpenWindowsCatalog)
);
options.Catalogs.Add(
    manager.GetLocalPackageCatalog(LocalPackageCatalog.InstalledPackages)
);

// Set search behavior
options.CompositeSearchBehavior = CompositeSearchBehavior.RemotePackagesFromAllCatalogs;

// Set installed scope filter
options.InstalledScope = PackageInstallScope.User;

var compositeCatalog = manager.CreateCompositePackageCatalog(options);
var connectResult = await compositeCatalog.ConnectAsync();

if (connectResult.Status == ConnectResultStatus.Ok)
{
    // Search across all catalogs
    var findOptions = new FindPackagesOptions();
    var result = await connectResult.PackageCatalog.FindPackagesAsync(findOptions);
    
    foreach (var match in result.Matches)
    {
        var package = match.CatalogPackage;
        
        // Check if installed
        if (package.InstalledVersion != null)
        {
            Console.WriteLine($"{package.Name} (Installed: {package.InstalledVersion.Version})");
            
            if (package.IsUpdateAvailable)
            {
                Console.WriteLine($"  Update available: {package.DefaultInstallVersion.Version}");
            }
        }
        else
        {
            Console.WriteLine($"{package.Name} (Not installed)");
        }
    }
}
CompositeSearchBehavior values:
  • LocalCatalogs - Search only local catalogs
  • RemotePackagesFromRemoteCatalogs - Search remote catalogs without checking installed status
  • RemotePackagesFromAllCatalogs - Search remote catalogs and check local catalogs for installed versions
  • AllCatalogs - Search both local and remote catalogs

​
Catalog Refresh

Update a catalog to get the latest package information: 
var catalogRef = manager.GetPredefinedPackageCatalog(
    PredefinedPackageCatalog.OpenWindowsCatalog
);

var operation = catalogRef.RefreshPackageCatalogAsync();
operation.Progress = (op, progress) =>
{
    Console.WriteLine($"Refresh progress: {progress}%");
};

var result = await operation;

if (result.Status == RefreshPackageCatalogStatus.Ok)
{
    Console.WriteLine("Catalog refreshed successfully");
}
else
{
    Console.WriteLine($"Refresh failed: {result.Status}");
    Console.WriteLine($"Error: 0x{result.ExtendedErrorCode:X}");
}
