FAQ: .NET Resume Keywords
Should I include version numbers (e.g., .NET 8)?
Yes! Specific versions demonstrate current knowledge. Include both the latest version you've used and indicate you stay current with .NET releases.
Is .NET Framework still worth including?
Yes, if you have experience. Many enterprises still run .NET Framework 4.8 applications. Include it for roles requiring legacy maintenance or migration expertise.
What about Blazor keywords?
Blazor is growing rapidly. Include "Blazor Server" or "Blazor WebAssembly" if you have experience. It's a differentiator for full-stack .NET roles.
Should I include both C# and .NET?
Yes! They're complementary. C# is the language, .NET is the platform. Include both as recruiters may search for either.
How do I show Azure expertise on a .NET resume?
List specific Azure services (App Service, Functions, SQL Database) rather than just "Azure." Include Azure certifications if you have them.
What testing keywords should I include?
Include your testing framework (xUnit, NUnit), mocking library (Moq), and testing types (unit testing, integration testing, TDD) you practice.
