Real .NET development services means the architecture survives the team doubling, not a scaffold handed off and forgotten. Eleven years running .NET in production: EF Core that doesn't leak under load, background jobs that don't silently fail at 2am. The decisions most .NET projects skip in year one and regret in year three.
Why Entalogics for .NET
Most teams hire a .NET development company expecting architectural judgment and inherit the same three problems instead — a DbContext that knows too much, controllers that do too much, background jobs nobody monitors until the queue is full.
AsNoTracking on every read path, output caching at the right layer, connection pooling configured from day one. .NET 8 is one of the fastest server runtimes available, and most teams give that speed straight back with N+1 queries nobody notices until traffic doubles and the DBA calls.
One folder per feature, with the handler, validator, and tests living together instead of scattered across six horizontal layers. A new engineer finds the code for any feature in under thirty seconds, and a new endpoint never means touching files across three different folders.
EF Core where the domain is genuinely complex and migrations matter. Dapper where read performance is measurable and EF's overhead isn't earning its keep. Redis for distributed cache and session. Each choice made per use case, not carried over out of habit.
Value objects instead of primitive obsession. Result types instead of thrown exceptions on paths that are actually expected to fail. FluentValidation sits at every entry point. When a domain type changes, the compiler finds every callsite before the code review even starts.
When .NET, when not
.NET is a serious framework with a real learning curve. We'll tell you on the first call if it's the right fit, or if a lighter runtime solves your problem for half the cost.

What we build with .NET
The shapes of .NET development we take on most often. Backend-heavy, enterprise-grade, built to still be maintainable when the team doubles.
Minimal APIs, versioned endpoints, FluentValidation at every boundary, structured logging, and OpenAPI docs that stay accurate because they're generated, not maintained by hand.
Blazor for complex internal UIs — multi-tenant data isolation, role-aware navigation, audit logging baked in from the start, WCAG compliance from the first sprint instead of the last.
Hangfire runs scheduled jobs with a real dashboard, MassTransit handles event-driven messaging, and the outbox pattern makes sure no message gets lost if a service restarts mid-processing.
gRPC handles typed internal service contracts, YARP routes at the API gateway, and OpenTelemetry shows exactly where a slow request actually spent its time.
The spreadsheet that became five spreadsheets. The Access database three departments depend on that nobody will admit still exists. We replace all of it.
.NET Framework migrated to .NET 8, Web Forms to Blazor, WCF to gRPC — one endpoint at a time, with the current system running the entire time we're migrating underneath it.
The playbook
The backend patterns that show up on almost every .NET development engagement. Proven under real production load, not lifted from a conference talk.
P01
One folder per feature — command, handler, validator, and tests all living together, no horizontal layers requiring six files touched to ship one endpoint. New features don't disturb the old ones.
P02
FluentValidation sits at the API boundary, value objects replace domain primitives, Result types handle expected failure paths. A broken contract gets caught before the PR even opens.
P03
AsNoTracking runs on every read path. Redis handles caching with a consistent invalidation strategy. Output caching covers stable responses. The database only does work that genuinely needs a database.
P04
MediatR handles in-process events, MassTransit with the outbox pattern handles out-of-process messaging. Side effects are guaranteed to run once, and guaranteed not to run twice on a retry.
P05
xUnit runs with Testcontainers, so tests hit a real database, a real message broker, a real Redis — not mocked infrastructure that quietly behaves differently from production at 3am.
P06
A YARP reverse proxy sits in front of both the legacy and new applications. Traffic shifts one endpoint at a time, and the old system keeps serving each route until the new one has actually earned it.
Signature case
A B2B logistics platform on .NET Framework 4.7 — 840ms average API response, controllers averaging 2,400 lines, a single EF6 DbContext with 340 tables, and a deployment process that took the application offline for every release. Migrated to .NET 8 vertical slice architecture in 12 weeks. No feature freeze. No downtime.
Before
p99 API 840ms · avg controller 2,400 lines · EF6 single DbContext · app offline per deploy
After
p99 API 94ms · avg handler 80 lines · EF Core bounded contexts · zero-downtime rolling deploy
Engagement shape
A typical .NET engagement runs endpoint by endpoint. The legacy system keeps serving traffic the entire time.
Two senior engineers go through the codebase — API response profiling, EF Core query analysis, a controller complexity inventory, a background job failure audit. Week one ends with a ranked RFC and a clear picture of where the real risk lives.
A .NET 8 baseline gets set up, vertical slice architecture gets established, FluentValidation and MediatR get wired in, one production endpoint goes live. p99 numbers land in your actual dashboards, not a local benchmark.
Every remaining endpoint migrates behind YARP, legacy and new running side by side. Every cutover ships with a kill-switch. Your roadmap keeps moving — a code freeze is never part of the ask.
The legacy service gets decommissioned, integration test coverage lands on the critical paths, OpenAPI docs get written. The runbook goes to your team, or we stay on retainer.
Stack
Our default .NET stack, chosen for production reliability not resume padding. Already on a stack? We'll slot in — but greenfield, this is where we start.
Engagement
No hourly retainer billing for "thinking time." Every path is fixed-quote or transparently rated.
One product, scoped and priced once, built entirely by senior engineers. RFC to launch in 8–14 weeks.
