Strategies for Building High-Performance Web Applications with .NET

Microsoft’s .NET is a versatile framework, one that is extensively used by skilled professionals to create a variety of applications. Whether you’re looking to create web applications, mobile apps, desktop apps, gaming, IoT, or AI applications, hiring .NET developers can give you access to one of the most dynamic and comprehensive software development platforms in the software industry.

Strategies for Building High-Performance Web Applications with .NET

In this blog post, we will explore how to build high-performance web applications with .NET, underscoring why .NET developers are such a crucial asset in modern software development.

Why .NET?

.NET has a vibrant ecosystem, a large community of developers, and comprehensive tooling support from Visual Studio and Azure. It offers an optimized development framework for building applications for Windows, macOS, Linux, and the cloud. Plus, its multi-language support and inherent scalability make it a popular choice among developers.

Building Web Applications with ASP.NET

ASP.NET, a subset of .NET, provides the tools and libraries needed to build web applications. Let’s look at how to create a high-performance application with ASP.NET.

Step 1: Use the latest version of .NET

Each new version of .NET comes with enhancements in terms of performance and security. Therefore, it’s always beneficial to work with the latest version. As of my knowledge cutoff in September 2021, .NET 6.0 was in preview with its general availability expected later in the year. Always ensure you’re using the latest stable version of .NET.

Step 2: Select the Right Project Template

ASP.NET Core offers several project templates, including MVC, Razor Pages, and Blazor. While all these templates offer different capabilities, Blazor Server and Blazor WebAssembly are becoming increasingly popular due to their ability to create interactive web UIs using C# instead of JavaScript.

Step 3: Leverage Dependency Injection

ASP.NET Core comes with built-in support for dependency injection (DI). DI allows for better code organization and facilitates more efficient unit testing. It is a great way to keep your application loosely coupled and easy to maintain.

High-Performance Techniques in .NET

The following are some of the key techniques to ensure your web applications are high-performance:

Utilize Async and Await

Async programming is essential for managing long-running tasks without blocking the main execution thread. This is crucial in web applications where blocking can cause the app to become unresponsive. The `async` and `await` keywords in C# make asynchronous programming straightforward.

public async Task<IActionResult> GetUsers()
    var users = await _userService.GetUsersAsync();
    return Ok(users);

Employ Caching

Caching can dramatically improve the performance of your web application by storing the results of expensive operations and reusing them. ASP.NET provides several caching options such as in-memory caching, distributed caching, and response caching.

public class UserController : Controller
    private readonly IUserService _userService;
    private readonly IDistributedCache _cache;

    public UserController(IUserService userService, IDistributedCache cache)
        _userService = userService;
        _cache = cache;

    public async Task<IActionResult> GetUsers()
        var cacheKey = "UserList";
        var users = await _cache.GetStringAsync(cacheKey);

        if (users == null)
            users = JsonConvert.SerializeObject(await _userService.GetUsersAsync());
            var options = new DistributedCacheEntryOptions().SetSlidingExpiration(TimeSpan.FromMinutes(5));
            await _cache.SetStringAsync(cacheKey, users, options);

        return Ok(JsonConvert.DeserializeObject<List<User>>(users));

Optimize Data Access

Entity Framework Core (EF Core) is a commonly used Object-Relational Mapper (ORM) with .NET, which reduces the need to write a lot of data access code. However, without proper usage, EF Core can cause performance issues.

1. Avoid Selecting Unnecessary Data: Instead of fetching complete entities, select only the necessary properties.

var users = await _context.Users
    .Select(user => new { user.Id, user.Username })

2. Batch Your Queries: EF Core has several techniques for batching queries together, reducing the number of trips to the database.

var tasks = new[]

User[] users = await Task.WhenAll(tasks);

Profiling and Diagnostics

Regular profiling and diagnostics are necessary to keep track of your application’s performance, a task expertly performed when you hire .NET developers. Equipped with tools like PerfView, Visual Studio Profiler, and dotTrace, these professionals can help analyze the runtime behavior of your application and locate any performance bottlenecks. Their technical expertise and deep understanding of the .NET ecosystem make them invaluable assets for maintaining and enhancing the performance of your software solutions.


.NET is a powerful, versatile platform for building high-performance web applications. By employing best practices and taking advantage of the features and tools provided by the platform, developers can create robust, scalable, and efficient applications that provide a high-quality user experience.

From employing asynchronous programming to optimizing data access, the .NET ecosystem provides developers with a host of options and opportunities to build high-performance applications. This wide array of possibilities makes it a wise decision to hire .NET developers, who can leverage these advantages to create robust, highly efficient software. So, whether you’re a seasoned .NET developer or just starting on your journey, or even a business looking to hire .NET developers, keep these tips in mind to ensure that your applications are as performant as they can be.

Always remember that the process of performance optimization is iterative. Skilled .NET developers make one change at a time, measure performance, and then make the next change. This way, they’re able to isolate any issues and understand exactly how changes are affecting application performance. The key is to continuously learn, adapt, and apply these learnings to your .NET projects. Good luck!
