Custom .NET Development Services for ASP.NET Core & Azure
Custom .NET Development Services from our team cover ASP.NET Core applications, Blazor front ends, and Azure-native architectures for businesses that have standardized on the Microsoft stack or are actively migrating off an aging .NET Framework codebase. We build on .NET 8 and later, connecting cleanly to existing enterprise infrastructure and modernizing legacy .NET Framework applications without forcing a disruptive full rewrite of working production systems currently in use. Talk to our .NET engineering team about your project and current stack today.
.NET Development Services We Provide
The .NET ecosystem has changed substantially since .NET Framework, and custom software development .NET work today typically means ASP.NET Core for APIs and web apps, Blazor for interactive front ends without a separate JavaScript framework, and deep Azure integration for cloud-native deployment and elastic scaling. We build across this full modern stack rather than treating each piece as an isolated, standalone service unconnected to the rest of your architecture. Each of these pieces connects to the others, so a Blazor front end and an Azure-hosted API share the same underlying platform.
ASP.NET Core APIs & Web Applications
ASP.NET Core APIs and web applications built on .NET 8 and later give you cross-platform deployment, significantly better performance than legacy .NET Framework, and a modern dependency injection model that simplifies testing considerably across the board.
Blazor Front Ends
Blazor lets teams build interactive web UIs in C# instead of JavaScript, which matters for organizations with strong .NET talent who would otherwise need to hire or contract separate frontend specialists for the same exact project.
Azure-Native Builds
Azure-native builds use managed services like Azure App Service, Azure SQL, and Azure Functions directly, reducing infrastructure management overhead considerably compared to a self-managed deployment your team would otherwise need to maintain and patch.
.NET Framework to .NET Core Migration
Migrating from .NET Framework to modern .NET is the single most common .NET engagement we run, because Framework is on extended support with a clear published end date, and the migration path affects performance, hosting costs, and long-term maintainability quite significantly. We scope this migration carefully rather than treating it as a routine dependency bump, since the risks of getting it wrong are real. We also validate that third-party dependencies have compatible modern replacements before committing to a fixed migration timeline and budget.
Scoping a Framework Migration
.NET Framework to .NET 8 migration typically requires replacing framework-specific APIs, updating third-party package dependencies, and rewriting configuration, which we scope through an automated compatibility scan before quoting a fixed migration timeline upfront.
Phased Migration Approach
A phased migration — moving services one at a time behind a compatibility layer — avoids the all-at-once cutover risk that has derailed .NET Framework migrations at organizations that tried a single big-bang rewrite instead of phasing it.
Connection to Legacy Modernization
This migration connects directly to our legacy system modernization work, since a .NET Framework application nearing end-of-support is functionally a legacy modernization project regardless of what the codebase happens to be called internally.
When .NET Beats Java or Node
Choosing between .NET, Java, and Node.js for a new project usually comes down to existing team skills, ecosystem fit, and specific performance characteristics, not one language being universally superior across every possible use case and workload type. We help clients reason through this rather than defaulting to whichever stack we happen to prefer building in most often, since fit matters more than preference. We walk through this tradeoff with every client during discovery rather than assuming .NET is automatically the right answer for them.
When .NET Is the Right Choice
.NET tends to win when your organization already runs Microsoft infrastructure, needs strong typing with excellent tooling, or is building enterprise line-of-business applications where Visual Studio's debugging experience saves genuinely real development time.
When Java or Node Fits Better
Java remains competitive for very large-scale distributed systems with heavy JVM tuning needs, while Node.js suits I/O-heavy real-time applications better than either — the right choice depends on your actual workload, not brand loyalty or trends.
Why Choose Us for .NET Development
Working with a .NET development partner should mean genuine depth in the current ecosystem, not developers who last touched .NET Framework years ago and are effectively relearning ASP.NET Core on your specific project's billable time and dime. We staff every .NET engagement with engineers actively working in the modern stack on a daily basis. That currency shows up directly in fewer bugs, faster delivery, and architecture decisions that hold up well over time.
Current Ecosystem Expertise
Our .NET teams work daily in ASP.NET Core, Blazor, and Azure, which matters because the ecosystem has changed enough since .NET Framework that outdated expertise shows up directly in architecture decisions and eventual performance.
Connected to Your Broader Enterprise Stack
We connect .NET builds to your broader enterprise software landscape and to custom software development engagements more broadly, since a .NET application rarely operates in true isolation from the rest of your systems.
Frequently Asked Questions
Should I migrate from .NET Framework to .NET 8, or is Framework still safe to use?
.NET Framework 4.8 is in extended support with no new feature development planned going forward, so new projects should start on .NET 8 or later. Existing Framework applications should plan a migration timeline, especially if they need new features or improved performance soon.
How long does a .NET Framework to .NET Core migration typically take?
A focused application migration typically takes 2 to 4 months to complete. A large enterprise system with many dependencies and custom integrations can take 6 to 10 months, depending on how many third-party packages need framework-compatible replacements found and tested.
Is Blazor a good replacement for a React or Angular front end?
Blazor works well when your team has strong C# skills and wants to avoid maintaining a separate JavaScript codebase entirely. For teams already invested in React or Angular tooling and talent, switching frameworks purely for Blazor's sake rarely makes sense financially.
Do you build on Azure specifically, or can you deploy .NET elsewhere?
We build Azure-native applications by default given the strong ecosystem fit, but .NET runs cross-platform and we deploy to AWS, on-premises infrastructure, or other clouds when that better matches your existing infrastructure and operational requirements and specific constraints in place today.
What does custom .NET development typically cost?
Costs range from roughly $50,000 for a focused API or internal tool to $300,000 or more for a full enterprise application with Azure integration and legacy migration. Our custom software development cost page breaks this down further by project type and phase.
