Hi Joshua Steward,

After digging deep I figured out that it was a minor mistake from my side. I was not referencing the method: AddSqlDapperClient() in my Startup.cs class as part of DI registration process. I made the change and validated it and found working fine as expected :)

Thanks again for your wonderful awesome great article on Dapper and Polly.

Thanks, Santosh

Glad you got things figured out, here's the code for this post [GitHub ConcurrentFlows.HashNode](https://github.com/ptsteward/ConcurrentFlows.HashNode/tree/master/ConcurrentFlows.DapperResiliency)

Hi Joshua Steward,

While running the code I got one more error : "Unable to resolve service for type 'Polly.IAsyncPolicy' while attempting to activate 'SqlDapperClient'."

Can you please help me to resolve this issue.

Any help on this request is much appreciated.

Thanks, Santosh

Hi Joshua Steward,

I tried to create a POC following your code sample as reference and came across few build issues.

I also wanted to know what is the usage of SQLConnectionFactory here. On trying to resolve the references related to SQLConnectionFactory. It is under the namespace :System.Data.Entity.Infrastructure. It is asking me to install EntityFrameWork latest version via nuget package manager.

Hence I request you to share me the reference code in this case.

Thanks, Santosh

Thanks Joshua Steward for detailed article on Dapper with Retry policies. Can you please share the complete code repository for my reference. Also I would like to understand what are the best practices to implement DI for PRODUCTION environment scenarios.
