Build production C# features with a dedicated squad that passes the Codebase Shape Test before day one
· Typical time to first merged PR: 10 to 14 days
Reviewed by Javier Uanini, CEO and delivery lead, Siblings Software.
You probably landed here because the roadmap needs steady C# throughput, your ASP.NET Core APIs are growing faster than internal hiring, and adding another marketplace contractor did not fix review culture or EF regressions. A dedicated C# development team from Siblings is a managed squad: tech lead, senior engineers, QA inside the sprint, delivery lead on your ceremonies. We operate from Córdoba, Argentina (GMT-3) under our dedicated teams practice.
This page covers buyer patterns, the Codebase Shape Test, published monthly bands, first-thirty-day governance, and when C# staff augmentation is enough. For platform-wide .NET Framework strangler work, see our dedicated .NET teams page with the Framework Fork Test.
Who hires a dedicated C# team (not staff aug)
API surface outpaced the internal lead
B2B SaaS teams hit this when ASP.NET Core services multiply but one architect still reviews every pull request. You need a squad with its own review bar and EF discipline.
Blazor or MVC rewrite with live customers
Feature freeze is not an option. A dedicated team ships incremental slices with shared domain libraries instead of a big-bang UI rewrite.
Compliance wants test and release evidence
SOC 2 or ISO audits ask for Definition of Done artifacts. A pod owns xUnit coverage, staging deploy logs, and change records per sprint.
Nearshore capacity without offshore roulette
You want GMT-3 overlap with US Eastern hours and engineers you meet before kickoff. Compare with nearshore staff augmentation if you already run ceremonies.
The Codebase Shape Test
Three honest yes answers mean a dedicated C# squad is the right commercial shape. Otherwise we steer you to staff aug or fixed scope.
We align implementation guidance with ASP.NET Core documentation and EF Core best practices. For broader outsourcing context see C# development outsourcing.
Monthly pricing bands (published)
Lean pod
Tech lead plus two engineers and part-time QA. Sustained API and service work.
Band: USD 11k to 18k per month. Minimum: 3 months.
Standard squad
Four to five engineers with embedded QA and delivery lead.
Band: USD 19k to 32k per month. Minimum: 3 months.
Enterprise squad
Six people including delivery lead for regulated or multi-service programs.
Band: USD 28k to 45k per month. Minimum: 4 months.
First thirty days on your repository
Week one: read-only discovery and Codebase Shape Test scoring. Week two: first merged PR through your pipeline. Days fifteen to thirty: governance dashboard with build success, test trend, and staging deploy cadence. If two metrics slip for two consecutive weeks, we schedule a thirty-minute executive readout with a remediation proposal.
Vetting includes a ninety-minute pair session on a real ASP.NET Core module: async controller edge case, EF query plan fix, and a failing integration test. Your lead drives half the keyboard.
Example engagement shape
Northline Benefits (composite). ASP.NET Core API behind a Blazor admin portal. Five-person C# squad reduced P95 list endpoints from 840ms to 120ms, introduced API versioning, and raised integration test coverage from 41% to 78% in four months. USD 29k per month.
Frequently Asked Questions
A C# tech lead, senior and mid-level ASP.NET Core engineers, QA with integration test discipline, and a delivery lead who owns sprint hygiene. Everyone is full-time on your engagement inside your Git host and CI pipeline. Commercially they sit on our payroll in Argentina. Minimum commitment is three months; after that, fifteen-day notice either side.
The Codebase Shape Test is our named checklist before proposing a C# dedicated squad. Q1: Is ASP.NET Core the delivery surface? Q2: Does data access need squad ownership including EF Core migrations and query tuning? Q3: Will the squad own release hygiene including CI gates and observability hooks? Two yes answers mean a dedicated squad beats staff augmentation.
A lean pod of tech lead plus two engineers and part-time QA is USD 11,000 to 18,000 per month. A standard ASP.NET product squad with four to five engineers and embedded QA is USD 19,000 to 32,000 per month. An enterprise squad with six people including delivery lead is USD 28,000 to 45,000 per month. Figures are all-in from our side for salaries, hardware, and employer taxes.
Staff augmentation drops individual engineers into your management chain; you still own architecture and code review culture. A dedicated team is a managed unit with tech lead, internal review bar, and accountability for sprint goals. Use augmentation when you already have a strong lead who only needs capacity. Use a dedicated team when nobody inside wants to own EF tuning, API versioning, and release readiness together.
Week one is read-only discovery: solution map, NuGet inventory, API surface audit, and a written squad proposal. Week two lands the first merged pull request, usually pipeline hardening or a low-risk API fix. Days fifteen to thirty establish the governance scorecard: build success rate, test coverage trend, mean time to staging, and escaped defect count on a shared dashboard.
Yes when scope is explicit. We often split UI lanes: Blazor or MVC for web surfaces, WPF or WinUI for desktop modules, with shared domain libraries. For Windows-only depth see our dedicated Windows app team and C# staff augmentation offering.
Yes. Engagements start with a mutual NDA and a Master Services Agreement that assigns source code and deliverables to you on payment. We work inside your repositories. We do not keep copies of client code after an engagement ends.
OUR STANDARDS
C# engagements ship like products, not staffing spreadsheets.
- API contracts versioned. Breaking changes require explicit consumer sign-off.
- EF queries profiled. No silent N+1 regressions in sprint review.
- Tests in the sprint. Integration coverage is part of Definition of Done, not a follow-up ticket.
- Honest scope. If Blazor and WPF together need two leads, we say so in week two.
