Build automation system for .NET

NuGet csi GitHub GitHub Build

C# interactive build automation system makes it easy to build .NET projects. It can be part of your solution as a regular console cross-platform .NET application, run C# scripts without compiling them, or even run in REPL mode - allowing you to run C# interactively.

Advantages

  • 3 compatible operating modes
  • Cross-platform
  • Debugging capability
  • No model limitations (Task, Target, DependsOn, etc.)
    • Regular .NET code
    • Best programming practices
  • Powerful API for building .NET projects
  • Summarised statistics

Operating modes

These modes are practically compatible, i.e., for example, a script can be run as a .NET project, and vice versa, with minimal or no changes.

Interactive (REPL)

Please see this page for installation details.

Launch the tool in the interactive mode:

dotnet csi

Simply enter C# commands sequentially one line after another and get the result in console output.

Running C# script

Run a specified script with a given argument:

dotnet csi ./MyDirectory/hello.csx World

Run a single script located in the MyDirectory directory:

dotnet csi ./MyDirectory World
Usage details 
dotnet csi [options] [--] [script] [script arguments]

Executes a script if specified, otherwise launches an interactive REPL (Read Eval Print Loop).

-- - Indicates that the remaining arguments should not be treated as options.

script - The path to the script file to run. If no such file is found, the command will treat it as a directory and look for a single script file inside that directory.

script arguments - Script arguments are accessible in a script via the global list Args[index] by an argument index.

@file - Read the response file for more options.

Supported options:

Option Description Alternative form
--help Show how to use the command. /?, -h, /h, /help
--version Display the tool version. /version
--source Specify the NuGet package source to use. Supported formats: URL, or a UNC directory path. -s, /s, /source
--property <key=value> Define a key-value pair(s) for the script properties called Props, which is accessible in scripts. -p, /property, /p
--property:<key=value> Define a key-value pair(s) in MSBuild style for the script properties called Props, which is accessible in scripts. -p:<key=value>, /property:<key=value>, /p:<key=value>, --property:key1=val1;key2=val2

.NET build project

Please see this page for details on how to install the project template.

Create a console project Build containing a script from the template build

dotnet new build -o ./Build

The created project contains 2 entry points:

  • Program.csx to run as a script 
    dotnet csi ./Build
  • Program.cs to run as .NET application 
    dotnet run --project ./Build

NuGet packages

Package name Link Description Installation
dotnet-csi NuGet Interactive .NET tool for REPL and running scripts dotnet tool install --global dotnet-csi
CSharpInteractive.Templates NuGet .NET build project template dotnet new install CSharpInteractive.Templates
CSharpInteractive NuGet A library for use in .NET build projects dotnet add package CSharpInteractive

Usage examples

API

Output, logging and tracing

Writing a line to a build log

WriteLine("Hello");

Writing a line highlighted with "Header" color to a build log

WriteLine("Hello", Header);

Writing an empty line to a build log

WriteLine();

Registering errors in the build log

Error("Error info", "Error identifier");

Registering warnings in the build log

Warning("Warning info");

Registering information in the build log

Info("Some info");

Registering trace information in the build log

Trace("Some trace info");

Arguments and parameters

Command line arguments

Args have got from the script arguments.

if (Args.Count > 0)
{
    WriteLine(Args[0]);
}

if (Args.Count > 1)
{
    WriteLine(Args[1]);
}

Using properties

WriteLine(Props["version"]);
WriteLine(Props.Get("configuration", "Release"));

// Some CI/CDs have integration of these properties.
// For example in TeamCity this property with all changes will be available in the next TeamCity steps.
Props["version"] = "1.1.6";

Microsoft DI

Using the Host property

Host is actually the provider of all global properties and methods.

var packages = Host.GetService<INuGet>();
Host.WriteLine("Hello");

Getting services

This method might be used to get access to different APIs like INuGet or ICommandLine.

GetService<INuGet>();

var serviceProvider = GetService<IServiceProvider>();
serviceProvider.GetService(typeof(INuGet));

Besides that, it is possible to get an instance of System.IServiceProvider to access APIs.

Using service collections

public void Run()
{
    var serviceProvider =
        GetService<IServiceCollection>()
            .AddTransient<MyTask>()
            .BuildServiceProvider();

    var myTask = serviceProvider.GetRequiredService<MyTask>();
    var exitCode = myTask.Run();
    exitCode.ShouldBe(0);
}

private class MyTask(ICommandLineRunner runner)
{
    public int? Run() => runner
        .Run(new CommandLine("whoami"))
        .EnsureSuccess()
        .ExitCode;
}

NuGet

Restoring a NuGet package of newest version

using HostApi;

IEnumerable<NuGetPackage> packages = GetService<INuGet>()
    .Restore(new NuGetRestoreSettings("IoC.Container").WithVersionRange(VersionRange.All));

Restoring a NuGet package by a version range for the specified .NET and path

using HostApi;

var packagesPath = Path.Combine(
    Path.GetTempPath(),
    Guid.NewGuid().ToString()[..4]);

var settings = new NuGetRestoreSettings("IoC.Container")
    .WithVersionRange(VersionRange.Parse("[1.3, 1.3.8)"))
    .WithTargetFrameworkMoniker("net5.0")
    .WithPackagesPath(packagesPath);

IEnumerable<NuGetPackage> packages = GetService<INuGet>().Restore(settings);

Command Line

Building custom command lines

using HostApi;

// Creates and run a simple command line 
"whoami".AsCommandLine().Run().EnsureSuccess();

// Creates and run a simple command line 
new CommandLine("whoami").Run().EnsureSuccess();

// Creates and run a command line with arguments 
new CommandLine("cmd", "/c", "echo", "Hello").Run();

// Same as previous statement
new CommandLine("cmd", "/c")
    .AddArgs("echo", "Hello")
    .Run().EnsureSuccess();

(new CommandLine("cmd") + "/c" + "echo" + "Hello")
    .Run().EnsureSuccess();

"cmd".AsCommandLine("/c", "echo", "Hello")
    .Run().EnsureSuccess();

("cmd".AsCommandLine() + "/c" + "echo" + "Hello")
    .Run().EnsureSuccess();

// Just builds a command line with multiple environment variables
var cmd = new CommandLine("cmd", "/c", "echo", "Hello")
    .AddVars(("Var1", "val1"), ("var2", "Val2"));

// Same as previous statement
cmd = new CommandLine("cmd") + "/c" + "echo" + "Hello" + ("Var1", "val1") + ("var2", "Val2");

// Builds a command line to run from a specific working directory 
cmd = new CommandLine("cmd", "/c", "echo", "Hello")
    .WithWorkingDirectory("MyDyrectory");

// Builds a command line and replaces all command line arguments
cmd = new CommandLine("cmd", "/c", "echo", "Hello")
    .WithArgs("/c", "echo", "Hello !!!");

Running a command line

using HostApi;

GetService<ICommandLineRunner>()
    .Run(new CommandLine("cmd", "/c", "DIR")).EnsureSuccess();

// or the same thing using the extension method
new CommandLine("cmd", "/c", "DIR")
    .Run().EnsureSuccess();

// using operator '+'
var cmd = new CommandLine("cmd") + "/c" + "DIR";
cmd.Run().EnsureSuccess();

// with environment variables
cmd = new CommandLine("cmd") + "/c" + "DIR" + ("MyEnvVar", "Some Value");
cmd.Run().EnsureSuccess();

Cancellation will destroy the process and its child processes.

using HostApi;

var cancellationTokenSource = new CancellationTokenSource();
var task = new CommandLine("cmd", "/c", "TIMEOUT", "/T", "120")
    .RunAsync(default, cancellationTokenSource.Token);

cancellationTokenSource.CancelAfter(TimeSpan.FromMilliseconds(100));
task.IsCompleted.ShouldBeFalse();

Running with timeout

If timeout expired a process will be killed.

TeamCity API

TeamCity integration via service messages

For more details how to use TeamCity service message API please see this page. Instead of creating a root message writer like in the following example:

using JetBrains.TeamCity.ServiceMessages.Write.Special;
using var writer = new TeamCityServiceMessages().CreateWriter(Console.WriteLine);

use this statement:

using JetBrains.TeamCity.ServiceMessages.Write.Special;
using var writer = GetService<ITeamCityWriter>();

This sample opens a block My Tests and reports about two tests:

// Adds a namespace to use ITeamCityWriter
using JetBrains.TeamCity.ServiceMessages.Write.Special;

using var writer = GetService<ITeamCityWriter>();
using (var tests = writer.OpenBlock("My Tests"))
{
    using (var test = tests.OpenTest("Test1"))
    {
        test.WriteStdOutput("Hello");
        test.WriteImage("TestsResults/Test1Screenshot.jpg", "Screenshot");
        test.WriteDuration(TimeSpan.FromMilliseconds(10));
    }

    using (var test = tests.OpenTest("Test2"))
    {
        test.WriteIgnored("Some reason");
    }
}

For more information on TeamCity Service Messages, see this page.
