One of the standout features in .NET 8.0 is the improved support for Azure Functions and serverless computing. The introduction of .NET Standard 3.0 and the migration to .NET 6.0 as the underlying runtime have brought several performance and productivity enhancements to Azure Functions.
Improved Cold Start Times
With .NET 8.0, the cold start times for Azure Functions have been significantly reduced, providing a more responsive and efficient serverless experience. This is achieved through various optimizations, including:
a. Native AOT Compilation: The new Native AOT (Ahead-of-Time) compilation feature in .NET 8.0 helps to reduce the startup time of your Azure Functions by pre-compiling the code to native machine code.
[FunctionName("MyFunction")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
return new OkObjectResult($"Hello, {name}");
}
b. Reduced Dependency Load: .NET 8.0 has streamlined the dependency loading process, minimizing the number of assemblies that need to be loaded during a cold start, further improving the overall startup performance.
c. Reduced Memory Footprint
.NET 8.0 also introduces improvements in memory management, leading to a reduced memory footprint for Azure Functions. This is particularly beneficial for cost-effective serverless computing, as it can help you optimize your Azure Functions to run within the available memory limits.
[FunctionName("MyFunction")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
// Use Span<byte> to read the request body
var buffer = new byte[1024];
int bytesRead;
using (var ms = new MemoryStream())
{
bytesRead = await req.Body.ReadAsync(new Memory<byte>(buffer));
await ms.WriteAsync(buffer.AsMemory(0, bytesRead));
// Return the response using Memory<byte>
return new OkObjectResult(ms.ToArray());
}
}
By leveraging the new `Span<T>` and `Memory<T>` types, you can reduce the amount of memory required for your Azure Functions, leading to more efficient resource utilization and potentially lower costs.
2. Azure Service Bus and Message Queuing
.NET 8.0 also brings improvements to working with Azure Service Bus and message queuing scenarios. These enhancements can help you build more reliable, scalable, and responsive cloud-based applications.
a. Azure Service Bus Triggers
One of the notable features in .NET 8.0 is the introduction of Azure Service Bus Triggers for Azure Functions. This allows you to easily integrate your Azure Functions with Azure Service Bus topics and queues, simplifying the implementation of event-driven architectures.
[FunctionName("ProcessQueueMessage")]
public static async Task Run(
[ServiceBusTrigger("my-queue", Connection = "ServiceBusConnectionString")]
string myQueueItem,
ILogger log)
{
log.LogInformation($"C# ServiceBus queue trigger function processed message: {myQueueItem}");
// Process the message
await ProcessMessageAsync(myQueueItem);
}
private static async Task ProcessMessageAsync(string message)
{
// Implement your message processing logic here
await Task.Delay(1000);
}
By using the `[ServiceBusTrigger]` attribute, you can seamlessly connect your Azure Function to Azure Service Bus, allowing you to focus on the business logic instead of managing the underlying infrastructure.
b. Improved Message Handling
.NET 8.0 also includes enhancements to the Azure Service Bus SDK, making it easier to handle messages reliably and efficiently. This includes features like:
i. Batch Message Processing: Leverage the new `ReceiveMessages` method to fetch and process messages in batches, improving throughput and reducing the overall number of roundtrips to the Service Bus.
var receiver = new ServiceBusReceiver("my-queue", new ServiceBusConnectionOptions
{
TransportType = ServiceBusTransportType.AmqpWebSockets
});
var messages = await receiver.ReceiveMessagesAsync(maxMessages: 10, maxWaitTime: TimeSpan.FromSeconds(5));
foreach (var message in messages)
{
// Process the message
await ProcessMessageAsync(message.Body.ToString());
// Complete the message
await receiver.CompleteMessageAsync(message);
}
ii. Automatic Message Completion: The SDK now supports automatic message completion, reducing the boilerplate code required to handle message lifecycles.
These improvements simplify the integration between your .NET 8.0 applications and Azure Service Bus, leading to more efficient and reliable message processing.
3. Azure SQL and Entity Framework Core Enhancements
.NET 8.0 also introduces several enhancements to the integration with Azure SQL and the Entity Framework Core (EF Core) library, making data-driven Azure applications more powerful and efficient.
a. Improved Performance with EF Core 8.0
The latest version of EF Core, which is tightly integrated with .NET 8.0, brings performance optimizations that can significantly improve the responsiveness of your Azure-hosted applications. These include:
i. Intelligent Caching: EF Core 8.0 introduces a new intelligent caching mechanism that can automatically identify and cache frequently accessed data, reducing the number of database queries.
using (var context = new MyDbContext())
{
var customers = await context.Customers.ToListAsync();
// The first query will trigger a database call, but subsequent
// queries for the same data will use the cached results
var customer = await context.Customers.FindAsync(1);
}
ii. Optimized Query Execution: The query engine in EF Core 8.0 has been enhanced to generate more efficient SQL queries, reducing the overall load on the Azure SQL database.
b. Azure SQL Data Types and Features
.NET 8.0 also provides better integration with the latest Azure SQL data types and features, allowing you to leverage the full capabilities of your Azure SQL databases.
public class Customer
{
public int Id { get; set; }
public string Name { get; set; }
public string? MiddleName { get; set; }
public DateTime CreatedAt { get; set; }
public DateTimeOffset UpdatedAt { get; set; }
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>()
.Property(c => c.MiddleName)
.HasColumnType("nvarchar(50)");
modelBuilder.Entity<Customer>()
.Property(c => c.CreatedAt)
.HasColumnType("datetime2(3)");
modelBuilder.Entity<Customer>()
.Property(c => c.UpdatedAt)
.HasColumnType("datetimeoffset(3)");
}
In this example, we're leveraging the new data type mappings in EF Core 8.0 to take advantage of the Azure SQL-specific data types, such as `nvarchar(50)`, `datetime2(3)`, and `datetimeoffset(3)`. This allows for more precise data modeling and storage in your Azure SQL databases.
4. Azure Authentication and Identity Management
.NET 8.0 also brings improvements to Azure authentication and identity management, making it easier to integrate your applications with Azure Active Directory (Azure AD) and other identity providers.
a. Azure AD B2C Integration
.NET 8.0 simplifies the integration with Azure AD B2C (Business-to-Consumer), allowing you to quickly set up secure user authentication and authorization for your Azure-hosted applications.
services.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme)
.AddAzureADB2C(options =>
{
options.Instance = "https://myb2ctenant.b2clogin.com/";
options.Domain = "myb2ctenant.onmicrosoft.com";
options.ClientId = "your-client-id";
options.CallbackPath = "/signin-oidc";
});
By using the `AddAzureADB2C` method, you can easily configure your .NET 8.0 application to integrate with Azure AD B2C, handling user authentication and authorization seamlessly.
b. Support for OIDC and OAuth 2.0
.NET 8.0 also includes improved support for OpenID Connect (OIDC) and OAuth 2.0, simplifying the integration with various identity providers, including Azure AD.
services.AddAuthentication(options =>
{
options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddCookie(CookieAuthenticationDefaults.AuthenticationScheme)
.AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options =>
{
options.Authority = "https://login.microsoftonline.com/your-tenant-id";
options.ClientId = "your-client-id";
options.ClientSecret = "your-client-secret";
options.ResponseType = "code";
options.SaveTokens = true;
});
This example demonstrates how you can configure your .NET 8.0 application to use OpenID Connect for authentication, allowing users to sign in with their Azure AD accounts.
5. Azure Monitoring and Logging Improvements
Finally, .NET 8.0 introduces enhancements to Azure monitoring and logging, making it easier to gather insights and troubleshoot your cloud-based applications.

using OpenTelemetry.Resources;
using OpenTelemetry.Trace;
var resourceBuilder = ResourceBuilder.CreateDefault()
.AddService("MyService");
var tracerProvider = Sdk.CreateTracerProviderBuilder()
.SetResourceBuilder(resourceBuilder)
.AddAzureMonitorTraceExporter()
.Build();
using (var tracer = tracerProvider.GetTracer("MyService"))
{
using (var span = tracer.StartActiveSpan("MyOperation"))
{
// Perform some operation
await DoSomethingAsync();
}
}
By configuring the OpenTelemetry integration and using the `AzureMonitorTraceExporter`, you can seamlessly send your tracing data to Azure Monitor, enabling advanced monitoring and troubleshooting capabilities.

var loggerFactory = LoggerFactory.Create(builder =>
{
builder.AddAzureMonitor(options =>
{
options.ApplicationId = "my-app-id";
options.LogLevel = LogLevel.Information;
});
});
var logger = loggerFactory.CreateLogger<MyClass>();
logger.LogInformation("This is a log message sent to Azure Monitor.");
In this example, we're configuring the `AzureMonitorLoggerProvider` to send our application's logs directly to Azure Monitor, providing a seamless integration between your .NET 8.0 application and the Azure monitoring platform.
