## What it is
dotnet/dotnet is the Virtual Monolithic Repository (VMR) containing all source code needed to build the .NET SDK, joining sources from repos like dotnet/runtime and dotnet/sdk. It enables whole-product source builds, distro packaging, and cross-repo changes identified by a single commit.

## Use cases
- build the entire .NET SDK from source on Linux
- package .NET natively into a Linux distribution
- make and test changes spanning multiple .NET repositories
- apply custom patches to .NET before building
- verify security fixes across the whole .NET product

## When to choose
- you are a distro maintainer (e.g. Red Hat, Canonical) packaging .NET from source
- you need to build .NET offline or with custom infrastructure
- you want to contribute changes that span multiple .NET product repos

## When to avoid
- you just want to install and use the .NET SDK to develop apps
- you want to contribute to a single .NET product repo like runtime or aspnetcore
- you need stable NuGet packages rather than source builds

## Facets
- artifact type: framework
- maturity: active
- function: build-tool, compiler, developer-tools
- domain: developer-tools, programming-languages, cross-platform
- platform: cross-platform, windows
- tags: dotnet, monorepo, vmr, source-build, sdk, linux, macos
