+Summary: The StackTrace.FrameCount returns 0 when called since another thread
+
+Description of Problem:
+
+The StackTrace.FrameCount getter returns 0 when it is being called from a 
+thread distinct from the application's main thread.
+
+
+Steps to reproduce the problem:
+    Execute this code:
+
+
+/*****************************************************
+ * Start code */
+
+using System;
+using System.Diagnostics;
+using System.Threading;
+
+
+namespace StackTraceTest
+{
+	public class StackTraceTest
+	{
+		public StackTraceTest()
+		{
+			MethodA();
+		}
+		
+		private void MethodA()
+		{
+			MethodB();
+		}
+		
+		private void MethodB()
+		{
+			StackTrace stackTrace = new StackTrace();
+			Console.WriteLine("StackTrace.FrameCount: [{0}]", 
+stackTrace.FrameCount);
+			int count = stackTrace.FrameCount;
+			for (int i = 0; i < count; i++)
+			{
+				StackFrame auxFrame = 
+stackTrace.GetFrame(i);
+				Console.WriteLine("StackFrame: [{0}: 
+{1}]", i, auxFrame);
+			}
+		}
+		
+		
+		public static void RunTest()
+		{
+			RunFirstTest();
+Console.WriteLine("***************");
+			RunSecondTest();
+		}
+		
+		private static void RunFirstTest()
+		{
+			Console.WriteLine("Running first test");
+			new StackTraceTest();
+		}
+		
+		private static void RunSecondTest()
+		{
+			Thread thread = new Thread(new 
+ThreadStart(ProcessSecondTestThread));
+			thread.Start();
+		}
+		
+		private static void ProcessSecondTestThread()
+		{
+			Console.WriteLine("Running second test");
+			new StackTraceTest();
+		}
+	}
+}
+
+/* End code *
+ ****************************************************/
+
+
+Actual Results:
+
+This is the output:
+
+Running first test
+StackTrace.FrameCount: [6]
+StackFrame: [0: MethodB at offset 0 in file:line:column <filename 
+unknown>:0:0]
+StackFrame: [1: MethodA at offset 0 in file:line:column <filename 
+unknown>:0:0]
+StackFrame: [2: .ctor at offset 6 in file:line:column <filename 
+unknown>:0:0]

+StackFrame: [4: RunTest at offset 0 in file:line:column <filename

+StackFrame: [5: Main at offset 0 in file:line:column <filename

+******************************
+Running second test
+StackTrace.FrameCount: [0]
+
+//As you can see, the code execute from the Thread, does not fill the 
+StackTrace.
+
+Expected Results:
+
+Running first test
+StackTrace.FrameCount: [6]
+StackFrame: [0: MethodB at offset 0 in file:line:column <filename 
+unknown>:0:0]
+StackFrame: [1: MethodA at offset 0 in file:line:column <filename
