Web Notes

This was a very long break since I posted my last web note however it`s time to share some fresh experience with the developer community. Today I want to show one of a handy solution which allowed me to simplify a Task chaining in .NET 4.5.1. Let`s start from defining a problem which in this case is a Task.ContinueWith<TResult>  method and the way how it`s designed for a tasks chaining. So if you want to use a chaining by using this function, all the time you need to access a parent task result property which in many cases causes a lot of redundancy in the code. To demonstrate this I use a simple async WebApi2 GET cities  auto-complete function which will query a database and later map result set of entities to collection of data transfer objects (DTO). // !!BADLY DESIGNED CODE!! [ HttpGet ] public   async   Task < HttpResponseMessage > Get( string  query)     {           return   await   this .cityRepository .AutocompleteCityAsync(query) . C
