.NET / C#

.NET and C# dominate enterprise backend development, and that makes them unavoidable in platform engineering. Many of the internal services that platform teams build on top of—identity providers, API gateways, legacy monoliths being decomposed into microservices—run on .NET. Understanding the runtime, its deployment model, and its operational characteristics is essential for building platforms that serve .NET application teams well.

From a platform engineering perspective, .NET’s strengths include first-class Azure integration, mature observability through OpenTelemetry’s .NET SDK, and a container story that has improved dramatically with minimal APIs and AOT compilation. Health check endpoints, structured logging with Serilog or the built-in logging abstractions, and gRPC support are all part of the standard toolkit. Platform teams can publish opinionated project templates via dotnet new that enforce organizational standards from the first commit.

The DevOps angle matters too. .NET builds are resource-intensive compared to Go or Python, so CI pipeline optimization—NuGet caching, incremental builds, and parallelized test execution—directly affects developer feedback loops. Understanding MSBuild, solution structure, and the NuGet dependency graph helps platform engineers design build systems that scale across hundreds of repositories without becoming a bottleneck.
