I am trying to use a couple of libraries in my asp.net website that I pulled in using NuGet.

Problem is I am getting this error:

Could not load file or assembly 'AWSSDK, Version=1.5.9.1, Culture=neutral, PublicKeyToken=cd2d24cd2bace800' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

One of the libraries I am trying to use needs to use the AWSSDK but apparently it is looking for an older version I can no longer get.

Is it possible to ignore this error?

This is a brand new website with no code in it yet, just what has been pulled in by NuGet, the web.config is empty.

EDIT:

I added Fusion logging and now I get:

=== Pre-bind state information ===

I get the same error if I add a bindingRedirect as mentioned in the comment below.

The latest (1.5.13.0) AWSSDK release seems to have been signed with a different key than the previous releases. So unfortunately a bindingRedirect won't work.

Proceed as follows:

Open the package manager console (Tools > Library Package Manager > Package Manager Console) and type:

PM> Uninstall-Package -Force AWSSDK

followed by:

PM> Install-Package AWSSDK -Version 1.5.12.1

Then double check your web.config file. Make sure that it only contains the following binding redirect for AWSSDK:

<dependentAssembly>
    <assemblyIdentity name="AWSSDK" publicKeyToken="cd2d24cd2bace800" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-1.5.12.1" newVersion="1.5.12.1" />
</dependentAssembly>

Now, your project should be good to go.

Try to edit .csproj file and remove the Version=1.5.9.1 from line where the assembly awssdk is referenced.
