 The **`/fsanitize=address`** compiler option enables [AddressSanitizer](../../sanitizers/asan.md), a powerful compiler and runtime technology to uncover [hard-to-find bugs](../../sanitizers/asan.md#error-types). Support for the **`/fsanitize=address`** option is available starting in Visual Studio 2019 version 16.9.
 
-The **`/fsanitize=fuzzer`** compiler option enables experimental support for [LibFuzzer](https://releases.llvm.org/3.8.0/docs/LibFuzzer.html). LibFuzzer is a coverage-guided fuzzing library that can be used to find bugs and crashes caused by user-provided input. We recommended you use **`/fsanitize=address`** with LibFuzzer. This option is useful for fuzzing tools such as OneFuzz. For more information, see the [OneFuzz documentation](https://www.microsoft.com/research/project/project-onefuzz/) and [OneFuzz GitHub project](https://github.com/microsoft/onefuzz).
