Redirects one assembly version to another.
<assemblyBinding> Element for <runtime>
The following sections describe attributes, child elements, and parent elements.
Specifies the version of the assembly that was originally requested. The format of an assembly version number is major.minor.build.revision. Valid values for each part of this version number are 0 to 65535.
You can also specify a range of versions in the following format:
n.n.n.n - n.n.n.n
Specifies the version of the assembly to use instead of the originally requested version in the format: n.n.n.n
This value can specify an earlier version than oldVersion.
Contains information about assembly version redirection and the locations of assemblies.
The root element in every configuration file used by the common language runtime and .NET Framework applications.
Encapsulates binding policy and assembly location for each assembly. Use one dependentAssembly element for each assembly.
Contains information about assembly binding and garbage collection.
When you build a .NET Framework application against a strong-named assembly, the application uses that version of the assembly at run time by default, even if a new version is available. However, you can configure the application to run against a newer version of the assembly. For details on how the runtime uses these files to determine which assembly version to use, see How the Runtime Locates Assemblies.
You can redirect more than one assembly version by including multiple bindingRedirect elements in a dependentAssembly element. You can also redirect from a newer version to an older version of the assembly.
Explicit assembly binding redirection in an application configuration file requires a security permission. This applies to redirection of .NET Framework assemblies and assemblies from third parties. The permission is granted by setting the BindingRedirects flag on the SecurityPermission Class. For more information, see Assembly Binding Redirection Security Permission.
The following example shows how to redirect one assembly version to another.
<configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="myAssembly" publicKeyToken="32ab4ba45e0a69a1" culture="neutral" /> <bindingRedirect oldVersion="188.8.131.52" newVersion="184.108.40.206"/> </dependentAssembly> </assemblyBinding> </runtime> </configuration>
