Frequently Asked Questions

What is the difference between ASP.NET and ASP.NET Core?

ASP.NET is the original, Windows-only framework for building web applications. ASP.NET Core is the modern, open-source, and cross-platform evolution of the framework.

It is significantly faster, more modular, and designed for building cloud-native applications. All new development should be done on ASP.NET Core (now simply part of the unified .NET platform, e.g., .NET 8).

Are ASP.NET developers only for building web applications?

While web applications are a primary focus, the .NET platform and the C# language are incredibly versatile. An expert ASP.NET developer's skills are applicable to building a wide range of solutions, including backend APIs for mobile apps, IoT services, desktop applications, and even game development with engines like Unity.

Why is Azure proficiency important for an ASP.NET developer?

Azure is Microsoft's cloud platform, and it has deep, native integration with the .NET stack. An ASP.NET developer proficient in Azure can build highly scalable, resilient, and cost-effective applications by leveraging services like Azure App Service, Azure Functions, Azure SQL Database, and Azure DevOps.

This synergy allows for faster development and more powerful solutions.

How much does it cost to hire an ASP.NET developer?

The cost varies significantly based on location, experience, and engagement model. Hiring developers from a certified offshore partner like Developers.dev provides access to top-tier, vetted talent at a more competitive price point than hiring locally in the US or Western Europe.

We offer flexible models, including Time & Materials, Fixed-Price Projects, and dedicated PODs (cross-functional teams) to fit different budget and project needs.

What is a 'POD' model and how does it benefit me?

A POD model provides you with a dedicated, cross-functional team of experts, not just individual developers. A typical ASP.NET development POD might include a project manager, a UI/UX designer, several .NET developers, and a QA engineer.

This 'ecosystem of experts' approach ensures all aspects of your project are covered, leading to better collaboration, higher quality, and faster time-to-market compared to hiring individual freelancers.
