When to Use

Starting automation from scratch
Need a guaranteed clean state
Processing specific files without user interaction
Want automatic cleanup when done

Basic Usage

var args = new ErikssonBeamLauncherArgs
{
    LicenseKey = Environment.GetEnvironmentVariable("ERIKSSON_LICENSE_KEY"),
    ExecutablePath = @"C:\Program Files\Eriksson Software\Eriksson Beam\ErikssonBeam.exe",
    FilesToOpen = new[] { @"C:\Projects\beam1.ebf", @"C:\Projects\beam2.ebf" },
    CloseErikssonBeamOnClientDisconnect = true,
    IdleTimeoutMs = 30000
};

using var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args);
var client = launcher.Client;

// Work with the client
var design = await client.PullBeamDesignerAsync("beam1");
design.DesignCriteria.ProjectInformation.DesignerName = "Updated";
await client.PushBeamDesignerAsync("beam1", design);

// Eriksson Beam closes automatically when launcher is disposed

Configuration Options

ErikssonBeamLauncherArgs

Property	Type	Default	Description
`LicenseKey`	string	`""`	Required. API authorization key
`ExecutablePath`	string	`""`	Required. Full path to ErikssonBeam.exe
`FilesToOpen`	string[]	`[]`	Files to open on launch
`CloseErikssonBeamOnClientDisconnect`	bool	`true`	Close Eriksson Beam when launcher is disposed
`IdleTimeoutMs`	int	`30000`	Client connection timeout (ms)
`MaxAttempts`	int	`10`	Connection retry attempts
`WaitTimeBetweenAttemptsMs`	int	`1000`	Delay between retries (ms)

Opening Files on Launch

You can open multiple files when launching:

var args = new ErikssonBeamLauncherArgs
{
    // ...
    FilesToOpen = new[]
    {
        @"C:\Projects\beam1.ebf",
        @"C:\Projects\beam2.ebf",
        @"C:\Projects\beam3.ebf"
    }
};

Each file must exist. If a file is not found, the launch will fail.

Disposal Behavior

The launcher manages the Eriksson Beam process lifecycle:

With CloseErikssonBeamOnClientDisconnect = true (Default)

using var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args);
// Work with client...
// When using block ends:
// 1. Client connection is closed
// 2. Eriksson Beam process terminates

With CloseErikssonBeamOnClientDisconnect = false

args.CloseErikssonBeamOnClientDisconnect = false;
using var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args);
// Work with client...
// When using block ends:
// 1. Client connection is closed
// 2. Eriksson Beam remains open for manual use

Error Handling

try
{
    using var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args);
    var client = launcher.Client;
    // ...
}
catch (FileNotFoundException ex)
{
    // ExecutablePath or FilesToOpen not found
    Console.WriteLine($"File not found: {ex.FileName}");
}
catch (DirectoryNotFoundException ex)
{
    // Directory in ExecutablePath doesn't exist
    Console.WriteLine($"Directory not found: {ex.Message}");
}
catch (ErikssonBeamNotRunningException ex)
{
    // Process failed to start or connection failed
    Console.WriteLine($"Launch failed: {ex.Message}");
}

Logging

Pass an ILogger for diagnostic output:

using Microsoft.Extensions.Logging;

// Create logger (example using console)
using var loggerFactory = LoggerFactory.Create(builder =>
{
    builder.AddConsole().SetMinimumLevel(LogLevel.Debug);
});
var logger = loggerFactory.CreateLogger<Program>();

var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args, logger);

Complete Example

using System.Threading.Tasks;
using ErikssonBeam.API.BeamClient;
using Microsoft.Extensions.Logging;

class BatchProcessor
{
    static async Task ProcessFiles(string[] files)

            ExecutablePath = @"C:\Program Files\Eriksson Software\Eriksson Beam\ErikssonBeam.exe",
            FilesToOpen = files,
            CloseErikssonBeamOnClientDisconnect = true,
            IdleTimeoutMs = 60000  // 1 minute for longer operations
        };

        try
        {
            using var launcher = await ErikssonBeamLauncher.LaunchErikssonBeam(args);
            var client = launcher.Client;

            foreach (var file in files)
            {
                var fileName = System.IO.Path.GetFileNameWithoutExtension(file);
                Console.WriteLine($"Processing {fileName}...");

                var design = await client.PullBeamDesignerAsync(fileName);

                // Modify design
                design.DesignCriteria.ProjectInformation.Date = DateTime.Now;

                await client.PushBeamDesignerAsync(fileName, design);

                // Save the file
                await client.SaveProject(fileName, file, overwriteExistingFile: true);
            }

            Console.WriteLine("All files processed successfully!");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
