Binding Redirect

Question

Need to reference a library 'configit.Base.dll' from one of my projects. Unfortunately my project already use Ionic.Zip.dll version 1.9.3.0 and it seem like configit.Base.dll needs version 1.9.1.8 of Ionic.Zp.dll, so when I try to run my program I get a load error. I've tried to add the following to mu .config file:

  <dependentAssembly>
    <assemblyIdentity name="Ionic.Zip" publicKeyToken="edbe51ad942a3f5c" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-1.9.1.8" newVersion="1.9.3.0" />
  </dependentAssembly>

without any success. If I run fuselogwv I get the following:

does this mean that Ioniz.Zip 1.9.3.0 is so different from 1.9.1.8, that it can't be loaded??

TIA

Answer 1

Check in CSPROJ file. If any version specified, remove it.

Answer 2

This does not mean that Ioniz.Zip 1.9.3.0 is so different from 1.9.1.8, that it can't be loaded.

The following line suggests the binding redirect did not occur:

LOG: Post-policy reference: Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c

Ensure your config entry is properly formatted (MSDN) and located in

C:\Local\Projects\Playground\ConfigItLoad1\ConfigItLoad1\bin\Debug\ConfigItLoad1.exe.Config

or your machine.config.
