Using Kubernetes, teams can deploy images across multiple underlying hosts, defining their desired availability, deployment logic, and scaling logic in YAML. Kubernetes evolved from Borg, an internal Google platform…

Frameworks

.NET offers a range of frameworks built on the base runtime, each addressing a specific domain: ASP.NET Core for web applications and APIs, EF Core for data access, and .NET MAUI for cross-platform client apps. Choosing the right framework for the job is one of the first decisions when starting a new .NET project.

Blazor

Blazor is a framework for building web applications using C and .NET that runs in the browser via WebAssembly. It allows developers to write C code that runs directly in the browser, eliminating the need for JavaScript.

.NET MAUI

.NET MAUI (Multi-platform App UI) is the cross-platform UI framework for .NET. It lets you build native Android, iOS, macOS, and Windows applications from a single C and XAML codebase, sharing business logic while still allowing per-platform customizations when needed.

.NET Aspire

.NET Aspire is an opinionated stack for building observable, production-ready cloud-native .NET applications. It provides curated packages for common cloud dependencies, service discovery, orchestration for local development, and built-in telemetry to make distributed applications easier to build and debug.

Orleans

Orleans is an open-source virtual actor model framework for building distributed, high-scale, and low-latency applications in .NET. It is designed to make it easy to build and operate large-scale, distributed systems, such as cloud services, IoT applications, and gaming servers.

SteelToe

Steeltoe is an open-source project that provides a set of libraries for building cloud-native applications on the .NET platform. The libraries are designed to work with the .NET Core runtime and provide a set of abstractions for common cloud-native patterns, such as service discovery, configuration management, and…

Dapr

Dapr (Distributed Application Runtime) is an open-source, portable runtime that makes it easy to build microservices-based applications that run on the cloud and edge. It provides a set of building blocks for building microservices, including service discovery, state management, pub-sub messaging, and more. It is…

Scalar

Scalar is a lightweight API platform for .NET that generates interactive API documentation and a UI for testing endpoints. It integrates with ASP.NET Core as a fast, configurable alternative to the default Swagger UI, built on the OpenAPI specification.

MediatR

MediatR is an open-source library for .NET that is designed to simplify the process of handling messages and commands in a clean, decoupled manner. It's particularly useful in applications that use the Command-Query Responsibility Segregation (CQRS) pattern and event-driven architecture. It provides a simple and…

FluentValidation

FluentValidation is an open-source library for .NET that provides a fluent, easy-to-use API for validating domain models. It allows developers to define validation rules using a fluent, chainable syntax. It separates validation rules into separate classes called validators, it supports async validation, custom…

Polly

Polly is an open-source library for .NET that provides a simple and flexible API for handling transient faults and other types of errors that occur during the execution of a service. It allows developers to define a set of policies, such as retry, circuit breaker, and timeout, that can be used to handle specific…

Marten

Marten is a .NET document database library built on PostgreSQL. It turns PostgreSQL into a document store, letting you persist and query .NET objects as JSON documents while still leveraging SQL features such as indexes, transactions, and native Postgres tooling.

Nuke

NUKE (Build Automation for .NET) is an open-source build automation tool for .NET projects. It is designed to be simple, flexible, and extensible, making it easy to automate the build, test, and deployment process of your .NET projects.

Benchmark.NET

It allows you to measure the performance of methods, classes, and entire assemblies, and provides a rich set of features for analyzing and comparing the results. It provides a wide…

Distributed Lock

A distributed lock coordinates access to a shared resource across multiple processes or services. It prevents concurrent modifications and race conditions by ensuring only one client holds the lock at a time, typically backed by a store such as Redis, ZooKeeper, or a database.
