Initialize RetryManager from EnterpriseLibraryContainer not working

I used this code to initialize RetryManager from the Enterprise Library:

using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
using Microsoft.Practices.EnterpriseLibrary.WindowsAzure.TransientFaultHandling;
using Microsoft.Practices.EnterpriseLibrary.WindowsAzure.TransientFaultHandling.SqlAzure;
using Microsoft.Practices.TransientFaultHandling;

...

var manager = EnterpriseLibraryContainer.Current.GetInstance<RetryManager>();
return manager.GetDefaultSqlConnectionRetryPolicy();

Now I have updated the NuGet Enterprise Library package to the latest version and EnterpriseLibraryContainer no longer exists.

How to initialize RetryManager using the new Enterprise Manager? It must be thread safe because my code is running on a web server.

I solved it like this:

Remove all old NuGet packages and install only those two:

<package id="EnterpriseLibrary.TransientFaultHandling" version="6.0.1304.0" targetFramework="net45" />
<package id="EnterpriseLibrary.TransientFaultHandling.Data" version="6.0.1304.0" targetFramework="net45" />

Add this code once to the application:

var strategy = new FixedInterval("fixed", 10, TimeSpan.FromSeconds(3));
var strategies = new List<RetryStrategy> {strategy};
var manager = new RetryManager(strategies, "fixed");
RetryManager.SetDefault(manager);

Then use the new connection class from Microsoft:

using (var connection = new ReliableSqlConnection(ConnectionString))
{
    connection.Open();
    ...
    command.ExecuteNonQueryWithRetry();
}

I also deleted the entire configuration from Web.Config, because now it is in my code.
