.NET 10 / C# 13 Skill
This codebase uses.NET 10 (LTS) with C# 13, configured with strict nullable reference types, implicit usings, and XML documentation. All services follow the same project configuration patterns and share infrastructure through Sorcha.ServiceDefaults.
Quick Start
Project Configuration
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>net10.0</TargetFramework>
<ImplicitUsings>enable</ImplicitUsings>
<Nullable>enable</Nullable>
<GenerateDocumentationFile>true</GenerateDocumentationFile>
<NoWarn>$(NoWarn);CS1591</NoWarn>
</PropertyGroup>
</Project>Service Setup Pattern
var builder = WebApplication.CreateBuilder(args);
// Always call AddServiceDefaults first
builder.AddServiceDefaults();
// Add service-specific dependencies
builder.Services.AddScoped<IMyService, MyService>();
// Add JWT authentication (shared from ServiceDefaults)
builder.AddJwtAuthentication();
var app = builder.Build();
app.MapDefaultEndpoints();
app.UseAuthentication();
app.UseAuthorization();Key Concepts
| Concept | Usage | Example |
|---|---|---|
| Primary constructors | Services with DI | class MyService(IRepo repo) |
| Collection expressions | Default values | List<T> Items = [] |
| Required members | DTOs/contracts | public required string Id {get; set;} |
| Records | Value objects, DTOs | public record PagedResult<T>(...) |
| Raw string literals | Multi-line docs | """Markdown content""" |

Documentation Resources
Fetch latest.NET documentation with Context7.
How to use Context7:
- Use
mcp__context7__resolve-library-idto search for "dotnet" - Prefer website documentation (IDs starting with
/websites/) over source code repositories when available - Query with
mcp__context7__query-docsusing the resolved library ID
Library ID: /websites/learn_microsoft_en-us_dotnet *(high reputation, 42K+ snippets)*
Recommended Queries:
- "C# 13 new features primary constructors"
- "collection expressions syntax"
- "required members properties"
- "nullable reference types"
