Error Checking

• Isolate threading bugs to the source code line where the bug occurs. See where affected variables get used by the threads and where the variables are declared.
• Learn possible causes of threading errors and suggested solutions with one-click diagnostic help.
• Use Intel Thread Checker within the Microsoft Visual Studio* .NET development environment.
