Quick Start

To program your Crestron system in C#, follow these steps:

1. Install the package via NuGet. You can use the following command in the Package Manager Console:

   dotnet add package Crestron.SimplSharp.SDK.Program

2. Import these namespaces in your code file(s) at a minimum:

   using Crestron.SimplSharp; using Crestron.SimplSharpPro;

   Depending on your application and the devices used, you might need to import additional namespaces.

3. Create a class that inherits from CrestronControlSystem and add a parameterless constructor: The constructor needs to exit in a timely fashion, otherwise the program will exit. You cannot send/receive data in the constructor

   public class ControlSystem : CrestronControlSystem { public ControlSystem() : base() { try { // Initialize Crestron threadpool Crestron.SimplSharpPro.CrestronThread.Thread.MaxNumberOfUserThreads = 20; } catch (Exception e) { ErrorLog.Error("Error in the constructor: {0}", e.Message); } } }

   Use the constructor to:

   • Initialize the maximum number of threads (max = 400)
   • Register devices
