DebuggableAttribute.IsJITOptimizerDisabled Property

Gets a value that indicates whether the runtime optimizer is disabled.

Namespace:  System.Diagnostics
Assembly:  mscorlib (in mscorlib.dll)

public bool IsJITOptimizerDisabled { get; }

Property Value

Type: System.Boolean
true if the runtime optimizer is disabled; otherwise, false.

A value of true enhances performance for runtime debugging, which can cause a decline in execution performance. A value of false enhances performance for execution. When IsJITOptimizerDisabled is set to false, stepping through code might result in a different behavior than when set to true because the compiler might reorder instructions or insert jumps to common code.
