Setting Up Azure Data Fabric Workspaces and Lakehouses Using C# SDKs

Introduction

Azure Data Fabric is Microsoft’s unified and intelligent data platform designed to simplify and centralize data governance, management, and access across distributed systems. It integrates multiple data services such as Data Factory, Synapse Analytics, and Data Lake Storage—into a coherent framework that empowers organizations to seamlessly ingest, store, process, and analyze structured, semi-structured, and unstructured data.

The core component of this modern data architecture is the Lakehouse, which combines the scalability and flexibility of data lakes with the transactional consistency and performance of traditional data warehouses. This hybrid approach supports a wide variety of workloads from large-scale data ingestion and processing to advanced analytics and machine learning without needing to duplicate or move data across silos.

This article offers a comprehensive, hands-on guide for setting up Azure Data Fabric components using C# SDKs. We will walk through each major step from provisioning cloud infrastructure to building a fully operational Lakehouse environment using industry-grade best practices and reusable C# code.

Prerequisites

Before you begin setting up Azure Data Fabric workspaces and lakehouses using C#, ensure you have an active Azure subscription with sufficient permissions—ideally, the Contributor role on the target resource group. You’ll need a development environment such as Visual Studio 2022 or later, or Visual Studio Code with the latest .NET SDK installed. Additionally, install the following necessary NuGet packages.

dotnet add package Azure.Identity 
dotnet add package Azure.ResourceManager 
dotnet add package Azure.ResourceManager.DataFactory 
dotnet add package Azure.ResourceManager.Synapse 
dotnet add package Azure.ResourceManager.Storage 

Understanding Azure Data Fabric Architecture

Azure Data Fabric is a unified analytics ecosystem that integrates multiple data services to deliver end-to-end data solutions. At the heart of this architecture is the resource group, which acts as a container for managing related resources such as compute, storage, networking, and analytics.

A typical Azure Data Fabric setup includes.

  • Resource Group: A Logical container that holds and organizes all resources deployed for the solution.
  • Azure Data Factory: A Data orchestration service that ingests, transforms, and moves data from over 90 sources, including on-premises and cloud systems.
  • Synapse Analytics Workspace: Unified analytics engine that supports T-SQL, Spark, pipelines, and integrated data exploration features.
  • Lakehouse: Hybrid data architecture combining the performance of data warehouses with the flexibility of data lakes. This Supports ML, analytics, and BI use cases.
  • Azure Data Lake Storage Gen2: Scalable file storage that supports hierarchical namespaces, ideal for structured and unstructured data.
  • Managed Identities: Secure authentication for inter-service communication without the need to manage secrets.
  • Private Endpoints and RBAC: Access control and network security to ensure compliance and protect sensitive data.

These components are tightly integrated and help deliver a secure, scalable, and high-performance data platform suitable for enterprise-grade solutions.

Setting Up Authentication in C#

To interact securely with Azure services through code, authentication is a critical step. Azure SDKs for .NET provide robust support for identity management using the DefaultAzureCredential class from the Azure.Identity package. This class simplifies authentication by automatically choosing the best available credential based on the environment the app is running in. It’s especially useful for developers because it supports multiple identity sources out of the box without requiring any code changes.

Here are the supported authentication mechanisms used by DefaultAzureCredential.

  • Azure CLI credentials: When the developer is logged in through the Azure CLI (az login), the SDK reuses that session.
  • Environment variables: It checks for specific environment variables like AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET.
  • Managed Identity: In deployed environments like Azure App Service or Virtual Machines, it uses the system-assigned or user-assigned identity.
  • Visual Studio or Visual Studio Code: Automatically picks up Azure credentials from the IDE’s signed-in session.
  • Interactive browser login: For local development, if none of the above work, it can prompt a login via browser (when enabled).
using Azure.Identity; 
using Azure.ResourceManager; 
 
// Use DefaultAzureCredential to authenticate with Azure 
var credential = new DefaultAzureCredential(); 
 
// Instantiate the ARM client with the credential 
var armClient = new ArmClient(credential); 

This setup ensures that you can develop and test locally with your IDE or CLI credentials and seamlessly transition to production with Managed Identities, improving both security and developer experience.

Creating Azure Resource Group

var armClient = new ArmClient(credential); 
var subscription = armClient.GetDefaultSubscription(); 
var rgData = new ResourceGroupData("East US"); 
var rgLro = await subscription.GetResourceGroups().CreateOrUpdateAsync("datafabric-rg", rgData); 

Provisioning Azure Data Factory

var dfData = new FactoryData("East US"); 
var dfLro = await subscription.GetResourceGroups()["datafabric-rg"] 
   .GetFactories().CreateOrUpdateAsync("df-instance", dfData); 

Data Factory enables ingesting data from over 90 sources, scheduling and transforming it via pipelines.

Provisioning Synapse Analytics Workspace

var synapseClient = armClient.GetSynapseWorkspaces(); 
var synapseData = new SynapseWorkspaceData("East US") 
{ 
   Identity = new ManagedServiceIdentity(ManagedServiceIdentityType.SystemAssigned), 
   DefaultDataLakeStorage = new DataLakeStorageAccountDetails 
   { 
       AccountUrl = "https://storageaccount.dfs.core.windows.net", 
       Filesystem = "lakehouse-container" 
   } 
}; 
var synLro = await subscription.GetResourceGroups()["datafabric-rg"] 
   .GetSynapseWorkspaces().CreateOrUpdateAsync("synapse-workspace", synapseData); 

Creating Azure Storage for Lakehouse

var storageData = new StorageAccountCreateOrUpdateContent( 
   new StorageSku(StorageSkuName.StandardLRS), StorageKind.StorageV2, "East US") 
{ 
   IsHnsEnabled = true // Important for hierarchical namespace (Data Lake) 
}; 
var storageLro = await subscription.GetResourceGroups()["datafabric-rg"] 
   .GetStorageAccounts().CreateOrUpdateAsync("datalakestore", storageData); 

Creating a Lakehouse Resource in Synapse

A lakehouse is often represented as a Spark-enabled workspace with structured metadata.

var lakehouseData = new LakehouseData("East US") 
{ 
   StorageAccountUrl = "https://datalakestore.dfs.core.windows.net", 
   ContainerName = "lakehouse-container" 
}; 
await synapseClient.CreateOrUpdateLakehouseAsync("datafabric-rg", "synapse-workspace", "lakehouse1", lakehouseData); 

Configuring SQL Pools and Access Roles

// Add dedicated SQL pools: 

var sqlPoolData = new SqlPoolData("East US") 
{ 
   Sku = new SynapseSku("DW100c") 
}; 
await synapseClient.CreateOrUpdateSqlPoolAsync("datafabric-rg", "synapse-workspace", "sqlpool1", sqlPoolData); 


// Assign RBAC roles programmatically: 

var roleAssignment = new RoleAssignmentCreateParameters 
{ 
   PrincipalId = userObjectId, 
   RoleDefinitionId = roleId 
}; 
await armClient.GetRoleAssignments().CreateOrUpdateAsync(roleScope, roleNameGuid, roleAssignment); 

Automating Infrastructure with C# Scripts

// Main automation program: 

public static async Task Main(string[] args) 
{ 
   var credential = new DefaultAzureCredential(); 
   var armClient = new ArmClient(credential); 
 
   // Create RG, Storage, DF, Synapse, Lakehouse 
   await CreateResourceGroup(armClient); 
   await ProvisionDataFactory(armClient); 
   await ProvisionSynapse(armClient); 
   await SetupLakehouse(armClient); 
} 

Monitoring and Cost Management

  • Use Azure Monitor to log Data Factory runs and Synapse sessions.
  • Use tagging for chargeback.
var updateParams = new FactoryPatch() 
{ 
   Tags = new Dictionary<string, string> { { "env", "prod" }, { "owner", "data-team" } } 
}; 
await dfClient.Factories.UpdateAsync(rgName, dfName, updateParams); 

Best Practices and Governance

Effective management and governance are essential to ensure your Azure Data Fabric environment is secure, scalable, and compliant with organizational standards. Implementing best practices not only protects your data assets but also simplifies management and reduces operational risks. Governance involves setting policies, managing access controls, and applying standards that maintain consistency across your data infrastructure.

Key best practices and governance strategies include.

  • Enable Private Endpoints: Secure your Azure resources by limiting network access to private virtual networks, reducing exposure to the public internet, and minimizing the attack surface.
  • Use Azure Key Vault for Secrets Management: Store and manage sensitive information such as API keys, connection strings, and certificates securely in Azure Key Vault instead of hardcoding them in applications or configuration files.
  • Implement Role-Based Access Control (RBAC): Assign permissions based on user roles to enforce the principle of least privilege, ensuring users and services only have the access they need.
  • Tag All Resources: Apply consistent and meaningful tags to your resources for cost tracking, operational management, and auditing purposes. Tags help categorize resources by environment, owner, department, or project.
  • Apply Azure Policies: Use built-in or custom Azure Policies to enforce organizational rules such as naming conventions, resource types, allowed locations, and security configurations automatically.
  • Automate Infrastructure Deployment: Use Infrastructure as Code (IaC) tools like ARM templates or Terraform with C# SDK automation to ensure repeatable and consistent provisioning of resources.
  • Regular Monitoring and Alerts: Utilize Azure Monitor, Log Analytics, and Alerts to proactively track the health, performance, and security of your Data Fabric components.

Following these best practices and governance guidelines helps create a secure, compliant, and efficient data platform that supports your organization's growth and regulatory requirements.
