In short
Grape5 places India-based, pre-vetted .NET developers who build and maintain production C# systems: ASP.NET Core APIs, Entity Framework Core data layers, and background services.
Each is dedicated to your product, managed and backed by Grape5, with a free replacement if the fit is wrong and at least 4 hours of daily overlap with US hours.
When to hire .NET developers
- You are moving a legacy .NET Framework 4.x app, often WebForms or WCF, onto .NET 8, and need someone who can do it incrementally without freezing feature work.
- You have a React or Angular front end and need ASP.NET Core Web APIs behind it, with token auth, EF Core, and clean request validation.
- Your monolith is choking on synchronous work and you want background processing moved into hosted services or a queue consumer for throughput.
- You run on SQL Server and Azure and need someone to tune slow queries, fix EF Core N+1 problems, and wire up App Service or Functions.
How we vet .NET developers
Every engineer we put forward is screened by a senior Grape5 engineer before you meet them. For .NET developers, we look specifically at:
- Async correctness: they use async/await end to end, avoid sync-over-async traps like .Result and .Wait() that deadlock, and can explain when ConfigureAwait(false) actually matters.
- EF Core depth: they catch N+1 queries, know when to use AsNoTracking, handle migrations safely, and can drop to Dapper or raw SQL when the ORM is the wrong tool.
- DI and lifetimes: they choose scoped, transient, or singleton correctly and can explain the captive dependency trap and how it leaks state across requests.
- Resource handling: they use IDisposable and using correctly, reuse HttpClient instead of opening a socket per call, and can reason about GC pressure and memory leaks.
- Testing and safety: they write xUnit or NUnit tests, use WebApplicationFactory for integration tests, and turn on nullable reference types instead of muting the warnings.

Frequently asked questions
It depends on the individual, and we are upfront about that. Some of our .NET developers have spent years in older .NET Framework, WebForms, and WCF code, while others are strongest on modern .NET 8. Tell us whether the role is maintenance, migration, or greenfield, and Grape5 screens candidates for that specific mix before you interview them.
Vetting is done by senior Grape5 engineers, not a recruiter with a checklist. Beyond a live C# exercise, we run a system design conversation: how they structure controllers or minimal APIs, where validation and auth live, how they model data in EF Core, and how they handle failures and retries. Syntax is easy to fake; design judgment is not.
Usually yes, but we say so up front. Most .NET roles touch SQL Server, and many touch Azure and a JavaScript front end. We screen for the specific surrounding stack you name, whether that is App Service, Functions, a message queue, or a React client, so you are not hoping they pick it up later. If a skill is missing, we tell you.
Every Grape5 engineer keeps at least 4 hours of daily overlap with US working hours, so you can pair on a deadlock, a race condition, or a slow EF Core query in real time instead of trading messages across a full day. You set the overlap window that matches your standups and review times.
A typical start is 2 to 3 weeks, because the engineer is dedicated to your product rather than pulled from a marketplace pool. If the fit is wrong, whether it is skill, communication, or working style, Grape5 replaces the developer for free. You are not stuck managing a bad hire on your own, since we manage and back the engineer.
