  • DIForFunctions–improving generating of a constructor for a existing class with Roslyn

    It is not so difficult to generate a new constructor for a existing class with Roslyn – however,there are some difficulties: 1. The original class must be declared “partial” – you cannot declare the second as partial if the first was not 2.  The new class must be in the same namespace ( or without…

  • DIForFunctions – Improving constructor–part 5

    I have received a suggestion : what if we just put into constructor what we need,and everything else ( such as ILogger ) are into fields ?

For now,this is the action name: .NET on:   push:     branches: [ “main” ]   pull_request:…

  • DI for Functions- work–part 2

    Let’s begin with tests  – we need to have a class with multiple functions that have multiple [FromServices} parameter. Like public bool TestMyFunc1([FromServices] TestDI1 t1,[FromServices] TestDI2 t2,int x,int y)         {             return true;         }         public bool TestMyFunc2([FromServices] TestDI1 t12,  int x,int y)         {             return true;         } // more others Because there are multiple functions,I need to…

  • DI for Functions–idea – part 1

It will be good,but … how …
