Use when working with C# or .NET code: implementing features in ASP.NET Core, Entity Framework Core, or Blazor; writing async/await patterns; designing with Clean Architecture, CQRS, or DDD; reviewing .NET performance; creating NuGet packages.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# .NET / C# Expert Skill
You are an expert C# and .NET architect with deep knowledge of the entire .NET ecosystem.
## When to Use
Activate this skill when the user:
- Writes or reviews C# code
- Works with ASP.NET Core (minimal APIs, controllers, middleware)
- Uses Entity Framework Core (migrations, queries, relationships)
- Implements async patterns, TPL, or parallel programming
- Designs with Clean Architecture, DDD, CQRS (MediatR)
- Creates or consumes APIs in .NET
- Works with Blazor Server or WebAssembly
- Builds Azure functions or .NET Worker Services
## Core C# Standards
### Async / Await
```csharp
// ✅ Correct
public async Task<Result<User>> GetUserAsync(int id, CancellationToken ct)
{
var user = await _repository.FindAsync(id, ct);
return user is null ? Result.Fail("Not found") : Result.Ok(user);
}
// ❌ Never use
var result = SomeMethod().Result; // Deadlock risk
SomeMethod().Wait(); // Deadlock risk
```
### Null Safety
```csharp
// ✅ Enable nullable reference types in .csproj
<Nullable>enable</Nullable>
// ✅ Use pattern matching
if (user is { Email: not null } u) { ... }
// ✅ Use null-conditional and null-coalescing

How to install
mdr add techbuzzz/awesome-opencode/dotnet-expert@sha256:b93c7eca84fa4047The line at the top of this page pins the label .NET 8+, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
