The .NET Upgrade Decision

Running .NET Framework 4.x costs you more every quarter. Here is what that gap looks like in code.

Four outcomes your team gets on delivery day.

Performance
82k
requests per second, .NET 8 on Azure Container Apps

.NET 8 Minimal application programming interfaces handle more throughput with less memory than any previous .NET release. We build on the current LTS runtime so your platform benefits from every performance improvement Microsoft ships.

Cloud-native deployment options →
Security architecture
Zero-trust
from day one of the architecture design

JWT authentication, role-based access control, and Microsoft Identity Platform integration are designed in from the start. For regulated industries, we implement SOC 2-ready patterns and audit logging at the infrastructure layer.

Clean architecture
4-layer
CQRS + domain-driven design pattern

Every .NET project uses a clean 4-layer architecture: Presentation, Application (CQRS with MediatR), Domain, and Infrastructure. Your team can add a feature without touching layers it does not own. No tight coupling between concerns.

Test coverage
87%+
unit and integration test coverage on delivery

Every handler, service, and repository ships with xUnit tests. Integration tests run against real database containers using Testcontainers. Your team inherits a codebase where the test suite catches regressions before they reach production.

USAGORegulated E-commerce

USAGO operates in the regulated guns and ammo industry and required a custom multichannel dropshipping platform to unify order management, inventory, shipping, invoicing, and supplier coordination into one automated system.

Problem
Manual fulfillment workflows, limited supplier visibility, and no centralized system constrained scalability and growth.
Result
Fully automated dropshipping platform handling orders, inventory, shipping, invoicing, and supplier coordination from a single .NET system.

C# 12

Our primary language for all .NET projects. C# 12 adds primary constructors, collection expressions, and improved pattern matching. Every project uses nullable reference types, file-scoped namespaces, and the latest records and init-only patterns. We write idiomatic modern C#.

ASP.NET Core 8 Minimal APIs

Minimal application programming interfaces replace the traditional controller pattern with route-based endpoint definitions. Startup code shrinks from 200+ lines to under 30. Performance improves because the middleware pipeline is simpler. We use Minimal APIs for all new .NET 8 projects unless the use case specifically benefits from controllers.

Entity Framework Core 8

EF Core 8 with Azure SQL or PostgreSQL. Code-first migrations for schema management. Compiled queries for hot paths. Bulk updates and deletes without loading entities. We separate read and write models: EF Core for writes, Dapper or raw SQL for complex read queries.

Azure (primary cloud target)

Azure Container Apps for the .NET runtime. Azure SQL or PostgreSQL for data. Azure Service Bus for messaging. Azure Key Vault for secrets. Azure Monitor for observability. Application Insights for distributed tracing. The Azure ecosystem pairs naturally with .NET.

Blazor Server and WebAssembly

Blazor when the team wants to stay in C# for UI. Blazor Server for internal tools and admin panels where server-side rendering is appropriate. Blazor WebAssembly for SPAs that need client-side logic without JavaScript. We are pragmatic: React or Next.js when a richer UI ecosystem is needed.

ASP.NET Core SignalR

Real-time bidirectional communication over WebSockets with automatic fallback. Used for live dashboards, notification systems, collaborative tools, and operational monitoring. Scales with Azure SignalR Service for multi-server deployments without sticky sessions.

MediatR and CQRS

Command Query Responsibility Segregation implemented via MediatR. Each use case is a separate handler class. Commands change state. Queries return data. Cross-cutting concerns (logging, validation, authorization) are pipeline behaviors. The application layer is fully decoupled from both presentation and infrastructure.

Docker and container-native deployment

Every .NET 8 project ships with a multi-stage Dockerfile. The build stage compiles and publishes. The runtime stage uses the minimal .NET runtime image. No IIS. No Windows Server. The final image is lean, fast, and deployable to any container platform: Azure Container Apps, AKS, or self-hosted Kubernetes.

Common Questions

What engineering leads ask before a .NET engagement.

We develop on .NET 8, the current long-term support release. For teams running legacy .NET Framework 4.x applications, we assess modernization paths first. We never default to .NET Framework for new builds. Every project ships on .NET 8 with a clear path to .NET 10 when it releases.
A focused .NET application programming interface or backend service typically delivers in 6 to 12 weeks. Complex platform builds with integrations, multi-tenant architecture, or migration from legacy .NET Framework run 16 to 32 weeks. Every project starts with a 2-week discovery phase that produces an architecture design document before any code is written. See our .NET development pricing guide.
We are Azure-first for .NET projects, as Azure Container Apps, Azure Service Bus, and Azure SQL pair naturally with the .NET runtime. We can also deploy to AWS using ECS or EKS, or to GCP using Cloud Run. We recommend Azure for most .NET projects unless you have an existing cloud commitment elsewhere. See our cloud migration services if you are moving from on-premises to cloud.
Yes. .NET Framework to .NET 8 migration is a core service. We assess the existing codebase, identify migration blockers, and design a phased modernization plan using the strangler-fig pattern. Most migrations run in parallel with continued development on the legacy system, so your team does not stop shipping while the migration is in progress. See legacy application modernization.
.NET development engagements typically run between $60,000 and $350,000 depending on scope, integrations, and whether the project is a greenfield build or a modernization. We scope before we quote. The discovery phase is priced separately and produces the architecture plan that informs the engagement cost. Visit our pricing guide for a full breakdown.
When to Hire Dotnet Development

We are specific about fit before any commitment is made.

💻
Good fit
You are building a new .NET application programming interface, platform, or enterprise system and want it built on .NET 8 with clean architecture and full test coverage from day one
You are running a legacy .NET Framework application and want a phased migration to .NET 8 without stopping active development
You want the codebase, architecture decision records, and runbooks handed over on delivery day so your team can maintain it without calling us
You have a technical stakeholder who can review architecture proposals and make decisions on schema design, integration patterns, and deployment approach
🚫
Not a fit
You need a simple create-read-update-delete application programming interface or admin panel under $30,000. Our process adds overhead that outweighs the benefit for small-scope work.
You want us to develop on .NET Framework 4.x or use older patterns. We do not build on deprecated runtime versions.
You need the project completed in under 4 weeks. The discovery phase alone takes 2 weeks and is not compressible without accepting architecture risk.
