Keywork sslprotocols is not supported in .NET

Question

I am planning to update my minimum TLS version to 1.2 in the Azure portal.

So, I have updated StackExchange.Redis to 2.0 and added sslprotocols=tls12 in the Redis connection string.

But all I am getting is an error Keyword 'sslprotocols' is not supported.

I have tried many things but nothing helped me

Answer 1

I know the answer is kind of discernable from the comments, but this is such an important question I thought I'd make sure the answer is clear for everyone:

• Install StackExchange.Redis.StrongName 1.2.6 to your project even though it's deprecated and even though it's already a dependency of Microsoft.AspNet.SignalR.Redis

• You will need a web.config mapping like such:

    <dependentAssembly>
          <assemblyIdentity name="StackExchange.Redis.StrongName" publicKeyToken="c219ff1ca8c2ce46" culture="neutral"/>
          <bindingRedirect oldVersion="0.0.0.0-1.2.6.0" newVersion="1.2.6.0"/>
    </dependentAssembly>
  

• Setup the backplane like this:

        var connectionString = $"{server}:{port},password={password},ssl=True,sslprotocols=tls12,abortConnect=False";
        GlobalHost.DependencyResolver.UseRedis(new RedisScaleoutConfiguration(connectionString, "hubName"));`
  

You will now be able to set the Minimum TLS Version of your Redis Cache in Azure to 1.2.
