Just updated ImageResizer via NuGet, can't run app because it can't find BundleAttribute

问题

I was just trying to update Azure Storage, but doing that meant I needed to update the ImageResizer AzureReader and update the app to use .Net 4.5.2 (the Azure site is set for .Net 4.6). Now I've got everything at the newest version; I've cleaned and rebuilt the app. It works fine locally, but when I publish it to Azure, I get the following error. I can not get the diagnostics page to load.

Server Error in '/' Application.

Could not load type 'ImageResizer.Util.BundleAttribute' from assembly 'ImageResizer, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'.

All of my ImageResizer plugins are at version 4.0.4.

Any ideas?

回答1:

You are mixing v3 ImageResizer assemblies with v4 ImageResizer assemblies. Remove all ImageResizer* dll files and re-install exactly one version.

回答2:

maybe some of your other dependency is depending on ImageResizer 4.0.0.0

you can use assembly redirection as work-around

      <dependentAssembly>
        <assemblyIdentity name="someAssembly"
          publicKeyToken="32ab4ba45e0a69a1"
          culture="en-us" />

        <bindingRedirect oldVersion="4.0.0.0" newVersion="4.0.4.0" />
      </dependentAssembly>

You can verify the severity of your wrong versioning by enabling the File Version column in Explorer and looking in your /bin folder.

As you can see I have 4.2 for the main DLL but 3.4 for other DLLs.
