Questions

Common questions about our services in India

What version of .NET does DotTut develop on?

We primarily develop on ASP.NET Core 8 and .NET 9, with the ability to work on all .NET versions from .NET 6 onwards. We also maintain legacy .NET Framework applications.

Can DotTut migrate our old .NET Framework application to .NET 8?

Yes, .NET migration is one of our specializations. We assess your codebase, create a migration plan, and execute the migration with minimal disruption to your operations.

Do you use Blazor for frontend development?

We use Blazor Server, Blazor WebAssembly, and traditional Razor Pages/MVC depending on the project requirements. We also integrate React or Angular with ASP.NET Core APIs where appropriate.

What databases do you use with ASP.NET Core?

We primarily use SQL Server with Entity Framework Core, but we also work with PostgreSQL, MySQL, SQLite, and MongoDB depending on requirements. We specialize in database performance optimization.
