Net Tooling

.NET Tooling

Priority: P1 (OPERATIONAL)

Essential tooling for .NET development, testing, and CI/CD.

Implementation Guidelines

• Project Files: SDK-style .csproj. Use Directory.Build.props for shared settings.
• Central Package Management: Directory.Packages.props for version consistency.
• Testing: xUnit or NUnit. FluentAssertions for readable assertions. Moq for mocking.
• Code Analysis: Enable built-in analyzers. Consider StyleCop, SonarQube.
• Build: dotnet build, dotnet publish. Use Release config for production.
• EditorConfig: Consistent code style across team.
• CI/CD: GitHub Actions, Azure DevOps, or GitLab CI.

Anti-Patterns

• No packages.config: Migrate to PackageReference.
• No skipping tests in CI: Tests must pass before merge.
• No ignoring warnings: Fix or suppress with documented justification.
• No floating versions: Pin versions (8.0.0, not 8.*).

Code

<!-- Directory.Build.props (shared across all projects) -->
<Project>
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    <AnalysisLevel>latest-recommended</AnalysisLevel>
  </PropertyGroup>
</Project>

<!-- Directory.Packages.props (Central Package Management) -->
<Project>
  <PropertyGroup>
    <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
  </PropertyGroup>
  <ItemGroup>
    <PackageVersion Include="Microsoft.EntityFrameworkCore" Version="8.0.0" />
    <PackageVersion Include="FluentValidation" Version="11.9.0" />
    <PackageVersion Include="xunit" Version="2.6.6" />
  </ItemGroup>
</Project>

// xUnit test with FluentAssertions
public class UserServiceTests
{
    [Fact]
    public async Task GetUser_WithValidId_ReturnsUser()
    {
        // Arrange
        var mockRepo = new Mock<IUserRepository>();
        mockRepo.Setup(r => r.GetByIdAsync(1, default))
            .ReturnsAsync(new User { Id = 1, Name = "Test" });
        var sut = new UserService(mockRepo.Object);

        // Act
        var result = await sut.GetUserAsync(1);

        // Assert
        result.Should().NotBeNull();
        result!.Name.Should().Be("Test");
        mockRepo.Verify(r => r.GetByIdAsync(1, default), Times.Once);
    }
}
