C# resumes are read through the .NET lens — ASP.NET Core, Entity Framework, and Azure co-keywords determine ranking, and version markers (.NET 8, C# 12) separate active product work from legacy Framework maintenance.
It appears in 2% of 2,367 engineering postings in our 15 August 2026 snapshot .
Job descriptions rarely ask for C# alone — these co-terms appear in the same postings and are screened together. Cover the ones you've genuinely used.
Public ATS boards (Arbeitnow, Greenhouse, Ashby, Google Careers, Lever, RemoteOK, Remotive). Not LinkedIn or Indeed. Percentages are share of postings that already mention C#.
A skill in a list is a claim; a skill in a bullet with an outcome is evidence. Patterns to adapt with your real numbers:
“Built ASP.NET Core Web APIs with EF Core serving 600 req/s for a logistics platform, deployed via Azure DevOps to App Service”
“Refactored a WinForms line-of-business app to Blazor Server, cutting deployment friction for 300 internal users to zero-install”
Put "C#" in your skills section in its exact form, then prove it in at least one experience bullet with context and an outcome — a skill that appears only in a list reads as padding to recruiters. C# resumes are read through the .NET lens — ASP.NET Core, Entity Framework, and Azure co-keywords determine ranking, and version markers (.NET 8, C# 12) separate active product work from legacy Framework maintenance.
Job descriptions that ask for C# typically also screen for: AWS, Azure, Java, C++, Python. Include the ones you've genuinely used — co-keyword coverage is how ATS ranking separates real practitioners from list-padders.
List it only if you could answer interview questions about it comfortably. A safer honest framing for light experience is grouping it under a "familiar with" tier, separate from your core skills — inflated skill claims surface fast in technical interviews.
Paste a job description that requires it — RoleTuner shows whether your resume surfaces C# and its co-keywords the way an ATS reads them, free.
