Hire.NET developers in Turkey..NET is the backbone of many enterprise systems: ERP and CRM extensions, banking and insurance back ends, B2B portals, integration services and internal line-of-business applications. Our C# and.NET developers join your team or deliver a module end to end, working in your repositories, Azure subscriptions or on-premise servers, with a large daily overlap with European working hours. Below you will find when.NET is the right choice, typical projects, a seniority matrix, the ecosystem we work with, how we vet candidates, KPIs, pricing factors and how the contract protects your IP and data.

What.NET is and when to choose it
Modern.NET (8 and later) is a cross-platform, open-source runtime that runs on Windows, Linux and containers. With C#, ASP.NET Core, Entity Framework Core and a strong tooling ecosystem, it is a natural fit for organisations already invested in Microsoft technologies, Azure, SQL Server or Active Directory, and for systems where long-term support, performance and maintainability matter more than trendiness.
Typical problems.NET teams face
- Business-critical applications still on.NET Framework 4.x and Windows-only servers
- Monolithic solutions with slow builds and tightly coupled projects
- Integrations with SAP, ERP or legacy SOAP services that only one person understands
- Performance issues caused by inefficient Entity Framework queries
- Hard-to-hire senior.NET talent in local markets
Typical.NET projects
| Project type | Example scope |
|---|---|
| Web APIs and microservices | ASP.NET Core REST or gRPC services, authentication with Entra ID (Azure AD) or IdentityServer, API gateways |
| Enterprise web applications | Blazor, Razor Pages or MVC front ends; Angular or React SPAs over a.NET back end |
| Integration and middleware | Message-based integrations with Azure Service Bus or RabbitMQ, ERP and SAP connectors, scheduled workers |
| Modernisation | Moving.NET Framework applications to modern.NET, containerisation, cloud migration |
| Desktop and mobile | WPF and WinForms maintenance,.NET MAUI for cross-platform apps |
Seniority matrix

- EF Core change tracking, migrations and query performance
- Authentication and authorisation with JWT, OAuth 2.0 and Entra ID
- Testing approach and designing for testability
Practical task
Candidates build a small ASP.NET Core API with validation, persistence and tests, or refactor a legacy service class. We review structure, naming, error handling and tests.
Code review criteria
| Criterion | What we look for |
|---|---|
| Architecture | Clear separation of concerns without over-engineering |
| Correctness | Validation, null handling, cancellation tokens |
| Performance | Efficient queries, no blocking calls in async code |
| Security | Secrets out of code, input validation, proper authorisation checks |
| Tests | Meaningful unit and integration tests |
Typical team compositions
| Scenario | Suggested composition |
|---|---|
| Extending an existing product | 1–2 mid-level or senior.NET developers in your team |
| New enterprise application | 1.NET lead, 2–3.NET developers, 1 front-end developer, 1 QA engineer, part-time DevOps |
| .NET Framework modernisation | 1 architect, 2–3 senior developers, 1 QA engineer, DevOps for the cloud move |
Engagement and delivery models
Our.NET developers work remotely, on-site or in a hybrid setup. Remote is the most common setup; on-site or hybrid is often preferred for systems running on in-house servers, for regulated environments or during intensive analysis phases.
- Dedicated specialist (staff augmentation): one or more.NET developers join your team full time, follow your processes and report to your lead.
- Dedicated team: a cross-functional team with a lead, sized from 1 to 200+ people, that owns a product area or a backlog.
- Project-based delivery: a defined scope with milestones and acceptance criteria, delivered by a team we manage.
- Extended coverage: 7/24 shift plans for support, monitoring or release windows where the work needs it.
Process and typical timeline
| Step | What happens | Typical duration |
|---|---|---|
| 1. Discovery call | We clarify scope, stack, seniority, time zone overlap and working model | 1–2 days |
| 2. Shortlist | We share pre-screened.NET profiles with our technical assessment notes | About 1 week |
| 3. Your interviews | You interview the candidates; a trial task can be added | A few days |
| 4. Contract and onboarding | Service agreement, NDA and DPA signed, access set up, equipment ready | Typical start in 1–2 weeks |
| 5. Ongoing delivery | Regular check-ins, performance reviews and a replacement process if the fit is not right | For the agreed term |

Security, data protection, NDA and IP
You sign a B2B service agreement with 360 Soft; the specialists are engaged by us in Turkey. All work product is assigned to you under an IP assignment clause, and every team member signs confidentiality and IP undertakings before getting access. Where personal data is processed, we sign a GDPR data processing agreement (DPA) with Standard Contractual Clauses, or the UK IDTA for UK clients, and we comply with Turkey’s data protection law KVKK. Developers work in your repositories, Azure tenants and servers with access you control and can revoke. Turkish banking rules (BDDK) apply where our team works on regulated systems in Turkey; your own sector rules apply in your country.
Legal note
This page is general information, not legal advice. Contract terms are agreed per project. Our team operates under Turkish law and Turkish sector rules; the local rules of your own country (for example on data protection, sector regulation or contractor classification) also apply, so we recommend a review by your own counsel.
Illustrative scenario: moving from.NET Framework to modern.NET
Illustrative scenario, not a client case. A distributor runs its order management on ASP.NET MVC 5 and.NET Framework 4.7 on Windows servers. A small team first adds integration tests, extracts shared libraries to.NET Standard, then moves the API layer to ASP.NET Core in containers while the old UI keeps running. After the cut-over, the application runs on Linux containers and releases go through an automated pipeline.
