Fusion binding Post-policy ignoring bindingRedirect

Question

I have a project with SignalR and Ext.net. Both require Newtonsoft.Json.

SignalR requires Newtonsoft.Json 4.5.0.0 and Ext.net requires 4.0.8.0.

My binding redirects are not working at all. In my web.config

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral"/>
  <bindingRedirect oldVersion="4.0.8.0" newVersion="4.5.0.0"/>
</dependentAssembly>

But when it goes to bind

=== Pre-bind state information ===
LOG: DisplayName = Newtonsoft.Json, Version=4.0.8.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed
 (Fully-specified)

WRN: Comparing the assembly name resulted in the mismatch: Minor Version

So as far as I can see, the Post-policy reference should be the redirected version, not the original request. Yet it's being completely ignored. I've run into this problem before with this project too, but in the past I've been able to just get the version it's asking for because there weren't two separate dependencies.

Answer 1

Change your binding redirect to:

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral"/>
  <bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="4.5.0.0"/>
</dependentAssembly>

This is did not work. Still ignores the bindingRedirect and the Fusion log is the same – Herder

Don't forget to include XML namespace in assemblyBinding element.

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
