    Error when upgrading 7.2.4 to 7.3

    Hello Our, I'm trying to upgrade from version 7.2.4 to 7.3 but I get this error.

    Could not load file or assembly 'Microsoft.Owin, Version=2.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    I'm using the manual upgrade path. Hope someone can help me with this.

    Best regards

    Gert

    Check your web.config

    Search for Microsoft.Owin and you'll see a line like 

      <dependentAssembly>
    <assemblyIdentity name="Microsoft.Owin" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" />
  </dependentAssembly>

    Check yours against what's in the umbraco zip you've downloaded (the one posted above is from 7.4.2 so don't just use this) - I suspect the version number is wrong in your local web.config so it's throwing an error (the Umbraco update documentation notes tell you to merge the web.config). Merge the changes from the latest webconfig into yours - a merge tool is useful for this - I use Winmerge.

    When you fix this one you might find you hit another similar dll version issue - keep going until it builds.

    HTH
