C# engineers for new builds and long-lived systems

Microsoft .NET is the backbone of many enterprise systems, from ERPs and finance tools to customer portals and integration services. Modern .NET runs cross-platform, performs well and fits naturally with Azure, SQL Server and Microsoft 365. Many organisations also carry older .NET Framework applications that still matter to daily operations and need careful attention.

Our .NET developers support IT teams in manufacturing, finance, healthcare and logistics, software vendors building on Microsoft technologies, and businesses moving desktop or WebForms apps to the web. Some roles are mainly greenfield ASP.NET Core work. Others involve keeping a large codebase stable while modernising it piece by piece. We ask which situation applies before recommending anyone.

We match developers on the specific parts of the ecosystem you use, such as Entity Framework, Blazor, MAUI, Azure Functions or Windows services. Once onboarded, they follow your architecture rules, code review standards and release calendar. Nexzem takes care of employment, equipment and continuity, so your technical leads keep full control of design decisions.

What our .NET Developers can do for you

C# and ASP.NET Core developers for enterprise apps, APIs, Azure workloads and legacy .NET Framework migrations.

  1. 01

    ASP.NET Core web APIs

    REST and gRPC services with Entity Framework Core, identity, policy-based authorisation, health checks and Swagger documentation, ready for containers or Azure App Service.

  2. 02

    Enterprise line-of-business apps

    Internal systems for approvals, inventory, HR and finance with role-based access, audit trails and reporting that match how your departments actually work.

  3. 03

    Blazor and MVC frontends

    Interactive web interfaces in Blazor or ASP.NET MVC with Razor, so C# teams can build complete features without switching languages.

  4. 04

    Legacy .NET Framework migration

    Assessment and staged migration of WebForms, WCF or older MVC apps to modern .NET, keeping the business running while each module moves across.

  5. 05

    Azure cloud services

    Azure Functions, Service Bus, Blob Storage, Key Vault and App Service deployments with infrastructure defined in code and pipelines in Azure DevOps or GitHub.

  6. 06

    SQL Server and data work

    Schema design, stored procedure cleanup, query tuning and reporting for SQL Server or PostgreSQL databases that sit behind your .NET applications.

  7. 07

    Desktop and cross-platform apps

    WPF, WinForms maintenance and .NET MAUI apps for teams that still need desktop tools or want one codebase across Windows, Android and iOS.

Why hire .NET Developers through Nexzem

  • Matched to your .NET stack

    We screen for the exact pieces you rely on, from EF Core and Azure to WCF or WinForms, instead of offering a generic C# profile.

  • Trial inside your process

    During a short trial the developer works through your review, branching and release rules, so you see how they fit your governance.

  • Working hours aligned to yours

    Agreed overlap means your architects and the developer can discuss design, review code and handle releases together in real time.

  • Enterprise-friendly confidentiality

    NDAs on request, access through your own identity provider where possible, and complete IP ownership for all deliverables.

  • Stable long-term capacity

    For multi-year systems we plan for continuity, with documented handovers and replacements if a developer has to leave.

How to vet a .NET developer

.NET developers range from those maintaining Windows-only .NET Framework applications to engineers building cloud-native services on modern .NET. Clarify which you need, then check fluency in C#, ASP.NET Core, dependency injection, Entity Framework Core and asynchronous programming. Strong developers understand when Entity Framework is the right tool and when a lighter approach such as Dapper performs better.

Migration experience is valuable because many organizations still run .NET Framework applications. Ask how candidates moved a project to modern .NET, which technologies had no direct equivalent, such as Web Forms or WCF, and how they handled them. Our .NET development page explains our approach to these migrations.

Enterprise skills matter too: integration with Entra ID and Microsoft 365, deployment to Azure or on-premises servers, security practices, logging and testing with xUnit or NUnit. Developers comfortable working within formal change processes and security policies adapt quickly to corporate environments.

  • Strong C# and ASP.NET Core fundamentals.
  • Efficient data access with Entity Framework Core or Dapper.
  • Experience migrating from .NET Framework.
  • Familiar with Azure services and Entra ID.
  • Writes automated tests and uses structured logging.
  • Works comfortably within enterprise processes.
  • Uses source control and CI pipelines in daily work.

Interview questions we use for .NET developers

Our questions reflect enterprise .NET work: APIs, data access, migrations, security and performance. Candidates explain decisions from real projects and review short C# samples, discussing correctness, readability and performance trade-offs that matter in systems used by many people every day.

Strong answers show understanding of async pitfalls, careful database access and practical migration strategies. We also look for awareness of how .NET applications run in containers and the cloud, since many organizations are moving away from Windows-only servers. Real examples from production carry the most weight.

  • What problems can async void and blocking on async code cause?
  • How do you find and fix a slow Entity Framework query?
  • How would you migrate a WCF service to modern .NET?
  • How do you configure authentication with Entra ID in ASP.NET Core?
  • How do you structure a solution so business logic is testable?
  • How would you run a .NET service in Linux containers?
  • How do you handle configuration and secrets across environments?

In-house vs dedicated .NET developer

Large organizations often have in-house .NET teams and add dedicated developers for migrations, integrations or peak workloads. Smaller companies with a single critical .NET application may not need a full-time developer and benefit from dedicated support that scales with demand. In both cases, documented architecture and shared code ownership protect continuity. Clear ownership avoids duplicated effort.

For cloud work, our Azure development services combine .NET expertise with infrastructure, identity and cost management. Dedicated developers can join your existing team or form a small team of their own for a specific modernization program. Clear handover notes keep knowledge in your organization.

Where .NET Developers make a difference

  • Migrating .NET Framework to modern .NET

    An enterprise with a Windows-only .NET Framework application adds developers who upgrade libraries, replace incompatible components and move services to modern .NET in containers, cutting hosting costs and restoring access to current tooling.

  • Microsoft 365 and Teams integration

    A .NET developer connects a line-of-business application to Microsoft Teams, Outlook and SharePoint through Microsoft Graph, so employees receive approvals and notifications where they already work, with single sign-on through Entra ID.

  • ASP.NET Core APIs for new channels

    A company launching mobile and partner channels builds secure ASP.NET Core APIs on top of existing systems, with authentication, rate limiting, logging and documentation that partner developers can use confidently.

  • Maintaining a critical internal system

    A business depending on an older .NET application for daily operations gets a dedicated developer who fixes issues, applies security updates and makes small improvements, while planning a gradual modernization path.

Hiring .NET Developers: FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

How is the price for a .NET developer set?

It depends on seniority, the parts of the Microsoft stack involved, overlap hours and engagement length. We bill monthly per developer after a short trial and confirm the figure following a free consultation.

Can your developers migrate our .NET Framework app to modern .NET?

Yes. They start with an assessment of dependencies and blockers, propose a staged plan and migrate module by module with regression testing at each stage.

Do your .NET developers work with Azure?

Yes. Many have built and deployed on Azure App Service, Functions, Service Bus, SQL Database and Key Vault, using Azure DevOps or GitHub Actions pipelines.

Can they follow our enterprise security policies?

Developers use your devices or VDI if required, your identity provider and your access controls. We sign NDAs on request and you own all IP.

Can we hire a .NET team rather than one developer?

Yes. We can form a small team with .NET developers, a frontend engineer and QA, working as a dedicated unit under your technical lead.

Can your .NET developers work on our on-premises servers?

Yes. Developers can work with on-premises Windows and SQL Server environments through your secure access methods, following your change management and security policies. Many organizations combine on-premises systems with cloud services, and our developers support both.

Do your .NET developers know Blazor?

Yes, several do. Blazor suits internal applications where teams want to use C# across frontend and backend. For public-facing applications with complex interactivity, we may recommend React or Angular with an ASP.NET Core API, depending on your team's skills.

We work with clients across the USA, UK, Australia, UAE, New Zealand and India.
