Using xCAD to create out-of-process (stand-alone) applications

xCAD framework can be used to create out-of-process (stand-alone) applications, such as Console, Windows Forms, WPF etc. in .NET Framework or .NET Core.

Call SwApplicationFactory.Create to connect to SOLIDWORKS instance in one of the following ways:

To the specified SOLIDWORKS version
To the latest SOLIDWORKS version (set the value of vers parameter to null)
By optionally providing additional arguments

In order to connect to existing (running process of SOLIDWORKS) use SwApplicationFactory.FromProcess method and pass the pointer to Process

using SolidWorks.Interop.sldworks;
using System;
using System.Threading.Tasks;
using Xarial.XCad.Documents;
using Xarial.XCad.Documents.Structures;
using Xarial.XCad.Enums;
using Xarial.XCad.SolidWorks;
using Xarial.XCad.SolidWorks.Documents;
using Xarial.XCad.SolidWorks.Enums;

namespace Xarial.XCad.Documentation
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var app = SwApplicationFactory.Create(SwVersion_e.Sw2020, ApplicationState_e.Background))
            {
                ISldWorks swApp = app.Sw;
                Console.WriteLine(swApp.RevisionNumber());

                var doc = app.Documents.Open(@"D:\model1.SLDPRT", Documents.Enums.DocumentState_e.ReadOnly);

                var swModel = (doc as ISwDocument).Model;

                Console.WriteLine(swModel.GetTitle());

                app.Close();
            }
        }
    }
}
