DebuggableAttribute Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Modifies code generation for runtime just-in-time (JIT) debugging. This class cannot be inherited.

Inheritance Hierarchy

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

Syntax

'Declaration
<AttributeUsageAttribute(AttributeTargets.Assembly Or AttributeTargets.Module, AllowMultiple := False)> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class DebuggableAttribute _
    Inherits Attribute

[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Module, AllowMultiple = false)]
[ComVisibleAttribute(true)]
public sealed class DebuggableAttribute : Attribute

The DebuggableAttribute type exposes the following members.

Constructors

	Name	Description
	DebuggableAttribute(DebuggableAttribute.DebuggingModes)	Initializes a new instance of the DebuggableAttribute class, using the specified debugging modes for the just-in-time (JIT) compiler.
	DebuggableAttribute(Boolean, Boolean)	Initializes a new instance of the DebuggableAttribute class, using the specified tracking and optimization options for the just-in-time (JIT) compiler.

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The DebuggableAttribute class controls how the runtime treats code within the module. The runtime might track extra information about generated code, and it might disable certain optimizations based on the values contained within this attribute.

A debugger might choose to ignore the DebuggableAttribute settings when loading an assembly. However, attaching a debugger to a running program may prevent the debugger from changing the settings because they have already been applied.

To use DebuggableAttribute with dynamic assemblies using the reflection emit DefineDynamicModule methods, emit DebuggableAttribute before calling the DefineDynamicModule methods to ensure that the settings are applied to the entire assembly.
