## What it is
Pose is a .NET isolation/mocking library that lets you replace any method—including static, non-virtual, and constructors—with a delegate at runtime. It is implemented entirely in managed code via Reflection Emit, requiring no profiling APIs or rewritten assemblies, and targets .NET Standard 2.0.

## Use cases
- mock static methods in c# unit tests
- replace datetime.now in tests
- shim non-virtual instance methods in .net
- isolate code under test from console and system dependencies
- mock constructors in dotnet tests
- alternative to microsoft fakes without unmanaged apis

## When to choose
- you need to mock static, non-virtual, or sealed methods in .NET tests
- you want a Microsoft Fakes alternative that works cross-platform without profiling APIs
- you test legacy .NET code that cannot be refactored for dependency injection

## When to avoid
- you only need to mock interfaces or virtual methods—a standard mocking library like Moq is simpler
- your project targets modern .NET versions beyond what Pose supports
- you need actively maintained tooling with ongoing support

## Facets
- artifact type: library
- maturity: maintenance
- function: mocking, testing
- domain: testing, developer-tools
- platform: dotnet, cross-platform, windows
- tags: shims, isolation-framework, reflection-emit, static-method-mocking, csharp, unit-testing, linux, macos
