Common Mistakes on C# Developer Resumes

  • Saying '.NET' without version specifics - .NET Framework 4.x and .NET 8 are very different. Always specify your version to signal modern skills.
  • No Azure cloud experience shown - C# and Azure go hand-in-hand. If you deploy to Azure, name the specific services you use.
  • Missing Entity Framework optimization details - EF Core is standard in .NET. Show query optimization results, not just 'used Entity Framework.'
  • Ignoring legacy migration experience - Enterprise .NET shops have WCF, Web Forms, or .NET Framework code. Migration experience is highly valued.
  • Not mentioning CQRS or clean architecture patterns - Modern .NET teams use MediatR, CQRS, and vertical slice architecture. Show your architectural awareness.
