Introduction We are in the new world of microservices and cross-platform applications which will be supported for multiple platforms and multiple heterogeneous teams can work on the same application. I like ASP.NET Core by the way its groomed to support modern architecture and adhere to the software principles. I am a big fan of dot net and now I become the craziest fan after seeing the sophisticated facility by dot net core to support infrastructure level where we can easily perform vertical and horizontal scaling. It very important design aspect is to keep things simple and short and by the way, RESTFul applications are build and it is a powerful mantra for REST-based application and frameworks. Some times we need to overrule some principles and order to handle some situations. I would like to share my situation of handling HTTP long polling to resolve the ASP.Net core 2 mins issue.

 Introduction When it comes to LINQ, we always have multiple options to execute the query for the same scenario. Choosing correct one is always challenging aspect and debatable one. In one of our previous articles   Any Vs Count  , we have done performance testing about best LINQ methods over .NET types. In this article, I would like to share about  Where(expression).FirstorDefault() vs .FirstOrDefault(expression) Approaches Performance testing for  Where(expression).FirstorDefault() vs .FirstOrDefault(expression) is very interesting IEnumerable<T> or ICollcetion<T>  .FirstOrDefault(expression) is better than  Where(expression).FirstorDefault() Public API To check the performance, I need some amount of data which should already available. So I decided to choose this  public api .
