OutOfMemoryException occurs after loading FileBasedProject

Question

OutOfMemoryException occurs after loading FileBasedPorject. Here is sample code to reproduce problem. 
 string[] files = Directory.GetFiles(@"Z:\projects", "*.sdlproj", SearchOption.AllDirectories); foreach (string file in files) { try { FileBasedProject project = new FileBasedProject(file); Console.WriteLine(project.GetProjectInfo().Name); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } 
 There are many Trados projects(more than 200) in Z:\projects. When loading project one by one and get information from FileBasedProject, memory usage is increased. Then OutOfMemoryException occurs. Can we release memory of FileBasedProject to prevent Exception ? How to clear memory of FileBasedProject object? I use Trados2017 Pro. 
 Best regards, Masayuki

Hi, Jesse 
Thanks for your information. 
I tried to use AppDomain in order to prevent memory problem, then it works fine. OutOfMemoryException doesn't occur.

e.g. 
 string[] files = Directory.GetFiles(@"Z:\projects", "*.sdlproj", SearchOption.AllDirectories); 
 foreach (string file in files) 
 { 
 AppDomain ad = AppDomain.CreateDomain("NewDomain"); 
 var workerType = typeof(Worker); 
 Worker remoteWorker = (Worker)ad.CreateInstanceAndUnwrap( 
 workerType.Assembly.FullName, 
 workerType.FullName); 
 remoteWorker.ProcessFile(file); 
 AppDomain.Unload(ad); 
}

Worker class 
public class Worker : MarshalByRefObject 
{ 
 public void ProcessFile(string projectPath) 
 { 
 try 
 { 
 FileBasedProject project = new FileBasedProject(projectPath); 
 Console.WriteLine(project.GetProjectInfo().Name); 
 } 
 catch (Exception ex) 
 { 
 Console.WriteLine(ex.ToString()); 
 } 
 } 
}
