Libraries Reference

The Power Platform Developer Suite (PPDS) ships a set of focused .NET libraries you can compose in your own applications. PPDS.Auth resolves credentials, PPDS.Dataverse manages connection pools and bulk operations on top of that, PPDS.Migration layers dependency-aware export and import on top of the pool, and PPDS.Plugins is a standalone net462 package of attributes for declarative plugin registration. The CLI, MCP server, and VS Code extension are all built on these same libraries.

Packages

Package	Published stable version	Target	Description
PPDS.Auth	1.1.2	net8.0;net9.0;net10.0	Credential providers, auth profiles, DPAPI-encrypted credential store
PPDS.Dataverse	1.3.2	net8.0;net9.0;net10.0	Connection pooling, bulk operations, throttle-aware resilience
PPDS.Migration	1.2.2	net8.0;net9.0;net10.0	Parallel exporter and tiered importer over CMT-format archives
PPDS.Plugins	3.0.1	net462	Declarative attributes for plugin steps, images, and Custom APIs
PPDS.Query	1.0.2	net8.0;net9.0;net10.0	SQL engine, FetchXML translation, and ADO.NET provider

Versions above were verified from public packages on October 30, 2026. See the maintenance release notes for the changes and validation scope.

PPDS.Plugins targets net462 as a compatibility baseline; plugin consumers can target .NET Framework 4.6.2 through 4.8. The CLI's accepted package asset groups are a separate deployment constraint; see plugin packages. The other libraries target .NET 8, 9, and 10.

PPDS.Auth

Handles credential acquisition, profile storage, and token caching. Profiles are persisted to disk with DPAPI encryption on Windows and platform keychain integration on other OSes.

Installation

dotnet add package PPDS.Auth

Key types

Type	Purpose
ICredentialProvider	Abstraction over all auth flows; returns authenticated ServiceClient
CredentialProviderFactory	Builds an ICredentialProvider from an AuthProfile
AuthMethod	Enum of supported flows (9 total — see below)
AuthProfile	Serialized profile with environment URL, tenant, and auth method
ProfileStore	File-backed profile collection
ISecureCredentialStore / NativeCredentialStore	Platform-specific secret storage
ProfileEncryption	DPAPI wrapper used by the profile store
IGlobalDiscoveryService	Resolves Dataverse environments via Global Discovery

Supported AuthMethod values: InteractiveBrowser, DeviceCode, ClientSecret, CertificateFile, CertificateStore, ManagedIdentity, GitHubFederated, AzureDevOpsFederated, UsernamePassword.

Usage

Register the shared singletons in DI, then create a provider from a profile:

using Microsoft.Extensions.DependencyInjection;
using PPDS.Auth.Credentials;
using PPDS.Auth.DependencyInjection;
using PPDS.Auth.Profiles;

var services = new ServiceCollection();
services.AddAuthServices();

var provider = services.BuildServiceProvider();
var profileStore = provider.GetRequiredService<ProfileStore>();
var credentialStore = provider.GetRequiredService<ISecureCredentialStore>();

var profile = profileStore.Get("dev");
using var credentials = await CredentialProviderFactory.CreateAsync(profile, credentialStore);

using var client = await credentials.CreateServiceClientAsync(profile.EnvironmentUrl);

AddAuthServices registers ProfileStore, EnvironmentConfigStore, and ISecureCredentialStore as singletons. They are file-backed and intended to be shared for the lifetime of the process.

PPDS.Dataverse

Connection pooling, bulk operation wrappers, throttle detection, and metadata queries over the Dataverse SDK. Pool connections are keyed by application user, and the pool tracks live degrees-of-parallelism hints from each connection so multi-tenant batch workloads stay within service-protection limits.

Installation

dotnet add package PPDS.Dataverse

Key types

Type	Purpose
IDataverseConnectionPool	Checkout-based pool with DOP tracking, throttle retries, and ExecuteAsync helper
IPooledClient	Scoped pool checkout — returns to pool on dispose
DataverseOptions / DataverseConnection	Configuration shape for the pool
IBulkOperationExecutor	CreateMultiple / UpdateMultiple / UpsertMultiple / DeleteMultiple wrappers
IMetadataQueryService	Cached entity and attribute metadata
IQueryExecutor	Query execution with pagination
IThrottleTracker	Per-connection throttle state

Usage

using Microsoft.Extensions.DependencyInjection;
using PPDS.Dataverse.BulkOperations;
using PPDS.Dataverse.Configuration;
using PPDS.Dataverse.DependencyInjection;
using PPDS.Dataverse.Pooling;

var services = new ServiceCollection();
services.AddDataverseConnectionPool(options =>
{
    options.Connections.Add(new DataverseConnection("Primary", connectionString));
    options.Pool.MaxPoolSize = 50;
});

var provider = services.BuildServiceProvider();
var pool = provider.GetRequiredService<IDataverseConnectionPool>();
var bulk = provider.GetRequiredService<IBulkOperationExecutor>();

await pool.EnsureInitializedAsync();

var result = await bulk.CreateMultipleAsync(
    entityLogicalName: "contact",
    entities: contacts,
    options: new BulkOperationOptions { BatchSize = 1000 });

AddDataverseConnectionPool has an overload that binds from IConfiguration, including multi-environment configs — see the XML docs on ServiceCollectionExtensions for the full configuration schema.

PPDS.Migration

Parallel export and dependency-ordered import over CMT-format ZIP archives. Migration does not take raw connection strings — it resolves IExporter and IImporter from DI on top of a PPDS.Dataverse connection pool.

Installation

dotnet add package PPDS.Migration

Key types

Type	Purpose
IExporter (default: ParallelExporter)	Reads a schema and writes a CMT ZIP
IImporter (default: TieredImporter)	Dependency-graph import with resumable phases
ExportOptions / ImportOptions	Parallelism, bypass flags, date shifting, user mapping
ISchemaGenerator	Builds a MigrationSchema from Dataverse metadata
IProgressReporter	Streams phase and entity progress
ExportResult / ImportResult	Counts, warnings, errors, timing

IExporter.ExportAsync takes (string schemaPath, string outputPath, ExportOptions? options, IProgressReporter? progress, CancellationToken cancellationToken) and returns Task<ExportResult>. IImporter.ImportAsync takes (string dataPath, ImportOptions? options, IProgressReporter? progress, CancellationToken cancellationToken) and returns Task<ImportResult>. Both interfaces also expose overloads that take pre-parsed MigrationSchema / MigrationData + ExecutionPlan for reuse across multiple runs.

Usage

using Microsoft.Extensions.DependencyInjection;
using PPDS.Dataverse.Configuration;
using PPDS.Dataverse.DependencyInjection;
using PPDS.Migration.DependencyInjection;
using PPDS.Migration.Export;
using PPDS.Migration.Import;

var services = new ServiceCollection();
services.AddDataverseConnectionPool(options =>
{
    options.Connections.Add(new DataverseConnection("Primary", connectionString));
});
services.AddDataverseMigration();

var provider = services.BuildServiceProvider();
var exporter = provider.GetRequiredService<IExporter>();
var importer = provider.GetRequiredService<IImporter>();

var exportResult = await exporter.ExportAsync(
    schemaPath: "./schema.xml",
    outputPath: "./export/data.zip",
    options: new ExportOptions { MaxDegreeOfParallelism = 8 });

var importResult = await importer.ImportAsync(
    dataPath: "./export/data.zip",
    options: new ImportOptions { BypassCustomPluginExecution = true });

AddDataverseMigration throws InvalidOperationException if AddDataverseConnectionPool has not been called first — the importer and exporter require a registered IDataverseConnectionPool.

PPDS.Plugins

Attribute-based plugin registration. Decorate your plugin classes and the CLI (or your own tooling) reads the attributes to register steps, images, and Custom APIs against Dataverse. The package retains its net462 compatibility target for .NET Framework plugin projects.

Installation

dotnet add package PPDS.Plugins

Attributes and enums

Type	Purpose
PluginStepAttribute	Message, entity, stage, mode, filtering, impersonation, bypass, invocation source
PluginImageAttribute	Pre/post images, attributes, entity alias, step linkage
CustomApiAttribute	Custom API unique name, binding, function/action, privilege
CustomApiParameterAttribute	Request/response parameters for a Custom API
PluginStage, PluginMode, PluginImageType	Step configuration enums
PluginDeployment, PluginInvocationSource	Deployment target and pipeline source (new in 2.1)
ApiBindingType, ApiParameterType, ParameterDirection, ApiProcessingStepType	Custom API enums (new in 2.1)

Compatibility with 2.x

PluginStepAttribute gained Deployment, RunAsUser, CanBeBypassed, CanUseReadOnlyConnection, and InvocationSource properties. CustomApiAttribute and CustomApiParameterAttribute add full Custom API authoring. These additions are source-compatible with 2.x. Version 3.0.0 changed the strong-name identity: consumers bound to the old public key token must rebuild against 3.x. See the Plugins changelog.

Usage

using Microsoft.Xrm.Sdk;
using PPDS.Plugins;

[PluginStep(
    Message = "Update",
    EntityLogicalName = "account",
    Stage = PluginStage.PostOperation,
    Mode = PluginMode.Synchronous,
    FilteringAttributes = "name,telephone1",
    CanUseReadOnlyConnection = false)]
[PluginImage(
    ImageType = PluginImageType.PreImage,
    Name = "PreImage",
    Attributes = "name,telephone1,revenue")]
public class AccountUpdatePlugin : IPlugin
{
    public void Execute(IServiceProvider serviceProvider)
    {
        // context.PreEntityImages["PreImage"] is populated by the registered image
    }
}

[CustomApi(
    UniqueName = "ppds_ProcessOrder",
    DisplayName = "Process Order",
    BindingType = ApiBindingType.Global)]
[CustomApiParameter(
    Name = "OrderId",
    Type = ApiParameterType.Guid,
    Direction = ParameterDirection.Input)]
[CustomApiParameter(
    Name = "ConfirmationNumber",
    Type = ApiParameterType.String,
    Direction = ParameterDirection.Output)]
public class ProcessOrderPlugin : IPlugin
{
    public void Execute(IServiceProvider serviceProvider) { /* ... */ }
}

PPDS.Query

The query library translates SQL to FetchXML and executes queries through the Dataverse connection pool. Its ADO.NET provider exposes PpdsDbConnection, PpdsDbCommand, and PpdsDbDataReader in PPDS.Query.Provider.

dotnet add package PPDS.Query

See the Query library guide and examples.

Versioning

Each library is versioned independently and follows semantic versioning. PPDS.Plugins is on the stable 3.x line; Auth, Dataverse, Migration, and Query each have their own stable 1.x line. The PPDS CLI pins specific library versions per release, so upgrading the CLI is the simplest way to stay on a known-good set.

Breaking changes are listed in each package's CHANGELOG.md in the main repo: PPDS.Auth, PPDS.Dataverse, PPDS.Migration, PPDS.Plugins, PPDS.Query.
