Compiler directive
A compiler directive is a source-level instruction that controls compilation or directs related tooling without being an ordinary executable statement.
.NET MAUI in Action
A compiler directive is a source-code instruction that controls compilation behavior, including conditional compilation for selected platforms.
- How it is used
- Controls which platform-specific code is compiled into a .NET MAUI app, especially for native handler customization.
- How deep it goes
- Demonstrates #if branches within handler mapping and contrasts them with partial classes and runtime platform checks.
- Examples
- Uses a BorderlessEntry with Android, Windows, iOS, and Mac Catalyst native border-removal branches.
- What you can do after
- Apply it via .NET MAUI to compile native control customizations only for their intended platforms.

A compiler directive is a source-level instruction that affects compilation or directs related tooling without being an ordinary executable statement.
- How it is used
- Uses a compiler directive to embed a corpus file into a Go program for endpoint-related game functionality.
- How deep it goes
- Explains directive syntax, package-scope placement, compiler handling, and blank imports, but does not develop directive implementation internals.
- Examples
- Demonstrates //go:embed corpus/english.txt, a package-level string variable, and a blank import of embed.
- What you can do after
- Apply it via Go's embed package to include a regular file's contents in compiled source.
