Could not load file or assembly 'System.Spatial' or one of its dependencies

Question

I get this error message:

Could not load file or assembly 'System.Spatial, Version=5.7.0.0, Culture=neutral, PublicKeyToken=49ba329had364evz' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I tried to uninstall/update System.Spatial and WindowsAzure.Storage Nuget packages but still get the error.

It's a dependency of WindowsAzure.Storage package, but funny thing is that I don't get this error when running my ASP.NET Web API project locally, but only on the Azure server.

I don't know where to find the assembly's manifest, is it packages.config?

How to get rid of this error? I already wasted two days :(

Answer 1

Changed the version details in configuration file based on DLL version present in bin folder of project having issue.

In configuration file it was referring to version 5.6.4 but I have changed to version 5.6.3 which resolved the error.

Before Change

<dependentAssembly>
        <assemblyIdentity name="System.Spatial" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.6.4.0" newVersion="5.6.4.0" />
      </dependentAssembly>

After change.

<dependentAssembly>
        <assemblyIdentity name="System.Spatial" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.6.3.0" newVersion="5.6.3.0" />
      </dependentAssembly>

Answer 2

if you are using visual studio, go to nugget package manager and view installed packages, and use update pane to update system.spatial package,

this solved my issue
