About .NET Development providers
Developers building enterprise apps, APIs and cloud services with Microsoft .NET and C#.
Technology-specific development companies bring deep experience in one language or framework. Choosing by stack makes sense when you already have a codebase or a clear technical direction.
Leading software and app development hubs include the United States, United Kingdom, Poland, Ukraine, India, Pakistan, the UAE and Latin America, with nearshore and offshore teams serving clients worldwide.
How to choose the best .NET Development Companies in 2026-2027
- Ask about .NET modernisation from older Framework versions.
- Ask for code samples or open-source contributions in that stack.
- Check seniority mix: how many senior engineers will be on your project.
- Ask how they keep up with framework releases and security updates.
What does it cost?
Rates follow the general development market, from under $25/hour offshore to $150+/hour onshore; niche stacks such as Rust or Elixir often command a premium.
Before you sign
Ask for a written proposal with scope, milestones, team members and exit terms, and speak to at least one current client of each shortlisted provider.

How this list is compiled
Worldwide view: Clutch-verified specialists (registered businesses independently verified on Clutch with a working website, ordered by their number of verified client reviews) followed by established industry leaders. Country view: the main list is strictly local. It shows only Clutch-verified firms with an office in the selected country and established firms based in that country that the iCreativez research team selected for their scale and track record. Large international firms and remote teams that serve the country appear in a separate, labelled section and are never counted as local. Where we have not yet verified enough local firms, the page says so instead of padding the list. Minimum project size, hourly rates and team size are as published by each company in November 2026. Inclusion is free and not paid for. Providers can request a review via our contact page.
