Properties

	Name	Description
	AssemblyName	Gets or sets the name of the target assembly. (Inherited from ProvideDependentAssemblyAttribute.)
	CodeBase	Gets or sets a relative path from $PackageFolder$, or an absolute path rooted from an environment variable substitution (of format %variable%). (Inherited from ProvideDependentAssemblyAttribute.)
	Culture	Gets or sets a string that specifies the language and country/region of the assembly. (Inherited from ProvideDependentAssemblyAttribute.)
	GenerateCodeBase	Gets or sets the generated code base element. When false, no corresponding CodeBase element is generated for the redirected assembly (used for assemblies in the GAC).
	Guid	Gets the identifier of this attribute instance. (Inherited from ProvideDependentAssemblyAttribute.)
	NewVersion	Gets or sets the version of the assembly to use instead of the originally-requested version.
	OldVersion	Gets the range of versions that will be redirected.
	OldVersionLowerBound	Gets or sets the lower bound (inclusive) of the range of versions that will be redirected.
	OldVersionUpperBound	Gets or sets the upper bound (inclusive) of the range of versions that will be redirected.
	PublicKeyToken	Gets or sets a 16-character hexadecimal number which is the token part of the strong name of the assembly being redirected. (Inherited from ProvideDependentAssemblyAttribute.)
	TypeId	Gets the current instance of this attribute. (Inherited from RegistrationAttribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	Register	Registers this attribute with the given context. (Inherited from ProvideDependentAssemblyAttribute.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Unregister	Unregisters this attribute. (Inherited from ProvideDependentAssemblyAttribute.)

Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

By using the ProvideBindingRedirection attribute, you can specify binding redirection for the installation of an upgrade to an extensible component. When you ship an extensible Visual Studio component, this attribute prevents users of the component from having to install an old version of a dependent component. If you use the ProvideBindingRedirection attribute, you don't need to manually update the exe.config file to redirect users of the old assembly version to the new version.

Adding a ProvideBindingRedirection assembly attribute is an easy way to add a binding redirection entry to the pkgdef file. The pkgdef file is used to install the extension.

The following example shows a ProvideBindingRedirection entry in the AssemblyInfo.cs or AssemblyInfo.vb file:

<Assembly: ProvideBindingRedirection(AssemblyName:="ClassLibrary1",
    NewVersion:="3.0.0.0", OldVersionLowerBound:="1.0.0.0",
    OldVersionUpperBound:="2.0.0.0")> 

[assembly: ProvideBindingRedirection(AssemblyName = "ClassLibrary1",
    NewVersion = "3.0.0.0", OldVersionLowerBound = "1.0.0.0",
    OldVersionUpperBound = "2.0.0.0")]

When the project is built, the following entry is added to the pkgdef file:

[$RootKey$\RuntimeConfiguration\dependentAssembly\bindingRedirection\{EE3E8305-3E91-51CD-0B2D-8E8EFFDD081C}]
"name"="ClassLibrary1"
"publicKeyToken"=""
"culture"="neutral"
"oldVersion"="1.0.0.0-2.0.0.0"
"newVersion"="3.0.0.0"
"codeBase"="$PackageFolder$\ClassLibrary1.dll"

You can also add a bindingRedirection entry directly to a pkgdef file.
