.NET development company in Chennai
We build and modernise business applications on Microsoft .NET — ASP.NET Core web apps and APIs, SQL Server databases and Azure hosting — and provide dedicated .NET developers for your team.
What does a .NET development company do?
A .NET development company builds and maintains software on Microsoft’s .NET platform using C#, ASP.NET Core, Entity Framework and SQL Server, often hosted on Azure. Wee4 Tech Solutions develops .NET web applications, APIs and enterprise systems, migrates legacy .NET Framework and Web Forms applications to modern .NET, and provides dedicated .NET developers from Chennai.
Many established businesses run critical systems on older .NET Framework, Web Forms or WCF code that is hard to change, hard to host and hard to hire for. Others need a new, secure API or portal built on a platform their IT team trusts.
We cover both: new ASP.NET Core development, and step-by-step modernisation of legacy .NET applications without stopping the business.

FAQ
.NET Development — frequently asked questions
Can you migrate our old .NET Framework application to .NET 8 or 9?
Yes. We assess the code, identify blockers such as Web Forms or WCF, and plan a phased migration — often running old and new modules side by side — so the business keeps running throughout.
Should we rebuild or migrate our legacy .NET system?
If the business logic is sound, migrating is usually faster and lower-risk. If the system no longer matches how you work, a rebuild may be better. We give a written recommendation after a short code assessment.
Can we hire a dedicated .NET developer?
Yes. See hire developers — .NET developers can usually start within a week of selection.
Do you work with international clients?
Yes. We work with clients in India and abroad, with agreed overlap hours for UK, Middle East, Europe and US time zones.
