Type error in Web.config when using Microsoft.Web.Redis.RedisSessionStateProvider

Questions

I am currently attempting to use a Redis cache for session, but am encountering some difficulties.

I’ve added this to my Web.config as per Cache ASP.NET Session State Provider - Azure Managed Redis | Microsoft Learn

<sessionState mode="Custom" customProvider="MySessionStateStore">
  <providers>
    <add name="MySessionStateStore" type="Microsoft.Web.Redis.RedisSessionStateProvider"
         host=""
         accessKey=""
         ssl="true" />
  </providers>
</sessionState>

Installed the relevant package using this command

nuget install Microsoft.Web.RedisSessionStateProvider -Version 4.0.1 -o ./bin -Framework net472

Here is a screenshot of the error:

Restarting IIS did not make any difference. What can I do to resolve this error?
