You can use libFuzzer as a SharpFuzz fuzzing engine on Linux and Windows.
1. Download the latest libfuzzer-dotnet release for your platform. Alternatively, you can compile libfuzzer-dotnet.cc (Linux) or libfuzzer-dotnet-windows.cc (Windows) from scratch using the following command:
clang -fsanitize=fuzzer libfuzzer-dotnet.cc -o libfuzzer-dotnet2. In your Main function, call Fuzzer.LibFuzzer.Run (instead of Fuzzer.Run or Fuzzer.OutOfProcess.Run).
3. Start fuzzing by running the fuzz-libfuzzer.ps1 script like this:
scripts/fuzz-libfuzzer.ps1 `
-libFuzzer "libfuzzer-dotnet-windows.exe" `
-project YourFuzzingProject.csproj `
-corpus Testcases
