ASP.NET developers for business-critical systems
Hire an ASP.NET developer from Ecomsolver to look after the internal systems your business cannot afford to have go down: portals, ERP add-ons, reporting tools and line-of-business apps built on Web Forms, MVC or ASP.NET Core. Our developers can support the system you have today while planning how to modernize it.
Many teams run older .NET Framework apps on Windows servers that are harder to host and secure each year. Your developer can migrate them to ASP.NET Core, containerize them, move them to Azure or AWS and set up CI/CD. They work in your Azure DevOps or GitHub, join your Teams or Slack, and overlap with your working hours.
What your ASP.NET developer can do
Support for existing .NET apps
Take over Web Forms, MVC or ASP.NET Core applications, fix bugs, add features and handle production issues during your business hours.
Migration to ASP.NET Core
Move .NET Framework apps to ASP.NET Core in planned stages, replacing unsupported libraries and keeping the current system live until cutover.
Web APIs and integrations
Build ASP.NET Core Web APIs for mobile apps, SPAs and partners, and integrate with Dynamics, SAP, payment gateways or other line-of-business systems.
SQL Server and data work
Optimize slow SQL Server queries and stored procedures, refactor data access with Entity Framework Core and build reports your teams rely on.
Cloud and DevOps
Containerize apps with Docker, deploy to Azure App Service or AWS, and set up CI/CD pipelines in Azure DevOps or GitHub Actions.
Modern frontends and AI
Pair your .NET backend with Blazor, React or Angular frontends, and add AI features such as document search or chat through Azure OpenAI.

Hiring ASP.NET developers: FAQs
Ask us on WhatsApp. A real person replies, usually within minutes during working hours.
Ask on WhatsAppCan I hire an ASP.NET developer to maintain an old Web Forms application?
Yes. Many clients hire an ASP.NET developer from us specifically to support Web Forms or MVC apps that are still critical to their operations. The developer sets up the environment, documents the system and handles fixes and features while you decide on modernization.
How do you migrate a .NET Framework app to ASP.NET Core?
The developer first audits dependencies and identifies libraries that do not run on ASP.NET Core. Then they migrate in stages, often starting with shared libraries and APIs, while the existing app stays live. Each stage is tested on staging before release.
Do your ASP.NET developers work with Azure?
Yes. They deploy to Azure App Service, Azure SQL and Azure Functions, set up pipelines in Azure DevOps or GitHub Actions, and can use Azure OpenAI for AI features. They also work with AWS if that is your cloud provider.
How do I hire an ASP.NET developer from Ecomsolver?
Book a free consultation and share your .NET version, hosting and goals. We send matched ASP.NET developer profiles for you to interview. Once approved and the NDA is signed, the developer starts onboarding, full-time, part-time or hourly.
Will the developer follow our security and change control rules?
Yes. Your developer works within your access policies, uses the accounts and VPN you provide, follows your change approval process and documents releases. We sign an NDA before any access, and all code stays in your repositories.
