Redirect Assembly Versions Using bindingRedirect Element
Sometimes it's mandatory to use a specific version of an assembly when various versions are available in place.
Simplest option is to use <bindingRedirect /> element under <dependentAssembly /> under <assemblyBinding /> in application configuration file.
For example in a configuration file that is presented below, version 1.0.0.0 of KeyvanAssembly is redirected to version 1.0.0.1. Using this configuration file, application applies version 1.0.0.1 of KeyvanAssembly rather than version 1.0.0.0.
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="KeyvanAssembly"
publicKeyToken="f405329a93f8ee7e"
culture="en-us" />
<bindingRedirect oldVersion="1.0.0.0"
newVersion="1.0.0.1"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
A nice point is you can force your application to redirect all available versions of an assembly to a specific version using "*" wildcard:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="KeyvanAssembly"
publicKeyToken="f405329a93f8ee7e"
culture="en-us" />
<bindingRedirect oldVersion="*"
newVersion="1.0.0.2"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>

Hi,
Thanks for the tip.
This looks quite useful, though it did not work for me when I tried it... Is there anything else that is needed to be able to use the "*" wildcard?
Thank you
You cannot specify a * for oldVersion, but you can specify a range.
The following will redirect everything before version 2.0.0.0 to the version 2.0.0.0:
<bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
