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

.NET Architecture Comparison
Compare both architectures side by side and see exactly what we change when we build or migrate your .NET system.
This is the architectural difference between a legacy .NET Framework application and a modern .NET 8 platform built by Redefine.

.NET Development Capabilities
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.
Is This the Right Engagement?
We are specific about fit before any commitment is made.
💻
Good fitYou 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 fitYou 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.
Not sure? Tell us about your .NET project and we will tell you honestly whether this engagement makes sense.
