Hello,
We are in the process of upgrading our highly customized solution from 9.13.8 to 9.20.1 and after quite a bit of fiddling with binding redirects in web.config, I have a mostly working solution in my local environment. However, I'm struggling with a particular 0x80131040 error related to System.Text.Encodings.Web.
Could not load file or assembly 'System.Text.Encodings.Web, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

System.Text.Encodings.Web, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51
Since the error is indicating it is trying to load version 5.0.0.0, I added the following binding redirect to web.config:
<dependentAssembly>
<assemblyIdentity name="System.Text.Encodings.Web" publicKeyToken="cc7b13ffcd2dddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
After restarting the server/app pool it still doesn't recognize the redirect. I added the dll to the GAC, but it didn't seem to make a difference. I also tried cleaning the solution. One other thing to note is that when viewing the logs in the Assembly Binding Log Viewer, it appears it's trying to load both version 5.0.0.0 and 6.0.0.0, even after deleting Temporary ASP.NET Files.
Any help would be much appreciated!
Regards,
Ben
