How .NET Core performes? 

Performance is a key reason companies choose to hire .NET Core developers (or just “.NET”). Independent benchmarks consistently place ASP.NET Core among the fastest web frameworks worldwide. According to TechEmpower, ASP.NET Core ranks in the top tier in raw throughput and latency. Microsoft’s ongoing enhancements to the runtime and garbage collector have significantly improved CPU usage and memory efficiency. 

ASP.NET Core’s Kestrel web server, introduced in .NET Core, provides high-speed request handling and asynchronous processing. Compared to Node.js or JavaScript, .NET Core often delivers faster API responses and better resource utilization, making it ideal for high-concurrency environments. 

Why hire .NET Core developers? 

.NET Core developers bring experience with modern development practices, including DevOps pipelines, containerization, microservices, and frontend integration using Blazor, React, or Angular. These developers can design clean architectures, write scalable APIs, and ensure long-term maintainability of your codebase. For your web development project, you can hire ASP.NET developers. 

Web application development  

Web development using .NET Core allows for rapid delivery of secure, high-performing applications. Developers use Razor Pages or the MVC pattern to create modular apps with clear separation of concerns. With built-in support for identity management, HTTPS, data protection, and input validation, .NET Core simplifies secure web development. 

Full-stack .NET Core applications often integrate front-end frameworks (React, Vue, Angular) via REST APIs or server-side rendering using Blazor. Developers follow modern UI/UX practices and mobile-responsive layouts, ensuring compatibility across devices. 

Cloud application development 

.NET Core is cloud-native by design. Developers use it to build and deploy scalable, containerized applications across Azure, AWS, or Google Cloud. Features like dependency injection, background services, and gRPC enable efficient cloud service development. 

Azure services, such as Azure Functions, App Services, and Cosmos DB, are tightly integrated with .NET Core, streamlining deployments. Kubernetes and Docker support enable developers to build distributed, microservices-based architectures with resilient failover and auto-scaling. 

Microsoft’s Azure documentation provides extensive resources for implementing .NET Core in cloud-native environments. 

Enterprise-grade app development 

.NET Core supports enterprise-grade architecture patterns, including layered architecture, CQRS, domain-driven design (DDD), and clean architecture. Developers leverage libraries such as Entity Framework Core, AutoMapper, MediatR, and Serilog for maintainable codebases. 

With enterprise security in mind, .NET Core provides built-in features for token-based authentication (OAuth, JWT), role-based access control, audit logging, and GDPR-compliant data handling. Developers also build APIs using OpenAPI/Swagger standards for easy integration with internal and third-party systems. 

Migration to .NET Core  

Migrating legacy .NET Framework apps to .NET Core allows companies improve performance, reduce hosting costs, and increase portability. Hire .NET developers to handle this transition by rewriting or porting existing codebases, refactoring outdated dependencies, and implementing modern architecture principles. Migration also supports containerization, cross-platform deployment (Linux, macOS), and better testing and CI/CD automation. Resources such as Microsoft’s Porting Assistant for .NET help guide developers through this process efficiently. 

CMS development 

Many organizations require custom content management systems (CMS) built to their workflows. You can hire .NET developers to implement headless CMS solutions, create custom content structures, and integrate digital asset management systems. CMS platforms such as Umbraco and Orchard Core are built on .NET Core and allow for full extensibility. Developers can also build secure admin panels with granular permissions, content scheduling, and version control, tailored to industries like publishing, healthcare, and e-commerce. 

Post-development maintenance 

Maintenance services ensure long-term application reliability. .NET Core developers perform ongoing monitoring, bug fixing, refactoring, and performance optimization. They use observability tools (Application Insights, ELK Stack) to proactively detect and resolve issues. 

Regular updates ensure compatibility with the latest .NET versions and security patches. Developers also manage database maintenance, third-party library updates, and code health reviews as part of their post-launch support.

What industries benefit from .NET development 

You can hire .NET developers to work on a project in any sector. The framework’s flexibility and cross-platform support make it ideal for industries requiring speed, security, and regulatory compliance. Developers can tailor solutions across domains such as biotech, energy, healthcare, and travel. 

Biotech 

In biotech, .NET developers build applications for data analysis, laboratory automation, and research workflows. These solutions often involve processing high-volume datasets from instruments, integrating with electronic lab notebooks (ELNs), or complying with regulatory standards like FDA 21 CFR Part 11. 

With .NET Core’s performance and compatibility with Python and R via .NET Interactive or ML.NET, biotech firms can leverage advanced analytics while maintaining enterprise reliability. Microsoft Azure’s offerings also support HIPAA and HITRUST compliance, making it a natural fit for biotech platforms. 

Oil and gas 

In the energy sector, .NET Core supports real-time data processing, predictive maintenance, and field service applications. Developers build solutions that integrate SCADA systems, monitor pipeline telemetry, or manage supply chains across upstream and downstream operations. 

Due to harsh operational environments, .NET Core’s compatibility with Windows IoT and Azure IoT Hub enables edge computing and remote monitoring. These apps often interface with rugged devices and require efficient communication protocols such as MQTT, REST, or Modbus.
