.NET debugger extensions installer (dotnet-debugger-extensions)

This article applies to: ✔️ .NET 6.0 SDK and later versions

Install

To install the latest release version of the dotnet-debugger-extensions NuGet package, use the dotnet tool install command:

dotnet tool install --global dotnet-debugger-extensions

Synopsis

dotnet-debugger-extensions [-h|--help] [options] [command]]

Description

The dotnet-debugger-extensions global tool installs the .NET debugger extensions, which enable better debugging experience in native debuggers like WinDbg and LLDB.

Note

The Windows Debugger (>= version 10.0.18317.1001 of WinDbg or cdb) automatically loads the extensions from the Microsoft extension gallery.

Options

  • --version

    Displays version information.

  • -h|--help

    Shows command-line help.

dotnet-debugger-extensions install

Installs the .NET debugger extensions locally for debugging .NET Core processes. On macOS and Linux, the .lldbinit file is updated so that the extension automatically loads at LLDB startup. If you're installing on Windows with older debugging tools (before version 10.0.18317.1001), you need to manually load the extension in WinDbg or cdb by running .load %USERPROFILE%\.dotnet\sos\sos.dll in the debugger.

This overwrites any previous installations from the dotnet-debugger-extensions or dotnet-sos installers.

Synopsis

dotnet-debugger-extensions install [--architecture <arch>]

Options

  • --architecture <arch>

    Specifies the processor architecture of the extension binaries to install. By default, dotnet-debugger-extensions installs the architecture of the host machine. Use this option when you want to install for an architecture that's different from the dotnet host architecture. For example, if you're running Arm32 binaries from an Arm64 host, you need to install with dotnet-debugger-extensions install --architecture Arm.

    The following architectures are available:

    • Arm
    • Arm64
    • X86
    • X64

  • --accept-license-agreement

    This option accepts and agrees to the licensing agreement without manual keyboard interaction. For use when console input is redirected.

dotnet-debugger-extensions uninstall

Uninstalls the .NET debugger extensions and, on Linux and macOS, removes it from LLDB configuration.
