C# and .NET Job Readiness

Resume snapshot

Skills: C# 12 / .NET 8, ASP.NET Core (minimal APIs + controllers), EF Core, LINQ, async/await, dependency injection, xUnit + Moq, Swagger/OpenAPI, Docker, Azure App Service / Functions. Projects: pl-csharp-passion (deployed), additional Unity demo if applicable. Bonus: Microsoft cert (AZ-204 Developer Associate is the relevant one).

Interview questions

'Explain the difference between Singleton, Scoped, and Transient DI lifetimes.' 'How does async/await work? What's a SynchronizationContext?' 'What is the N+1 query problem? How does Include() solve it?' 'Difference between IEnumerable, IQueryable, and List?' 'When would you use a struct vs a class?' 'Explain the C# nullable reference types.' 'Implement a generic repository pattern.'

Portfolio + 60-day plan

Five commitments.

1. 1

   1. Ship pl-csharp-passion deployed + with CI.

2. 2

   2. Add a SECOND smaller project, a Blazor WebAssembly UI for the same API, OR a Unity mini-game.

3. 3

   3. Contribute to a .NET OSS project: ASP.NET Core, EF Core, IdentityServer, or a smaller library (Polly, MediatR).

4. 4

   4. Get the AZ-204 Microsoft Developer cert (most marketable .NET cert in 2026).

5. 5

   5. (Optional) Write blog posts about your project decisions, Microsoft devs read dev.to + medium.

Common mistakes

Listing 'C#' with no public artifact. Knowing .NET Framework but not modern .NET. Not knowing async/await deeply (it's the most-asked C# topic). Underselling Unity work if you have it, game dev counts as 'shipped product'.
