Installation

NuGet Package

Install the main JasperFx package from NuGet:

bash

dotnet add package JasperFx

This brings in the core library including command line tooling, environment checks, and configuration support.

If you only need the utility extension methods (string, enumerable, reflection), you can install the lighter-weight core package:

bash

dotnet add package JasperFx.Core

.NET 9.0 SDK or later
A Microsoft.Extensions.Hosting compatible application (for CLI and environment check features)

After installing, verify the package is available by adding JasperFx to your host builder:

csharp

using Microsoft.Extensions.Hosting;

await Host
    .CreateDefaultBuilder()
    .ApplyJasperFxExtensions(args);

Run your application with the help command to see available commands:

bash

dotnet run -- help
