  • Demeter and Roslyn–part 1–idea

    Stop Your C# Code Talking to Strangers: Introducing a Law of Demeter Roslyn Analyzer The Law of Demeter (LoD),often summarized as “Only talk to your immediate friends,” is a valuable principle for writing loosely coupled,maintainable code. Code that follows LoD tends to be less fragile and easier to refactor. But manually checking for LoD violations?…

  • What I have learned by building .NET Stars -part 5 – always available data for a display website

    What I have learned by building .NET Stars -part 5 – always available data for a display website Dotnet Stars being a site just for displaying data,it does not require an API per se. Yes,for development purposes it needs a database and an API to display – but later – the data could be retrieved…

  • RSCG-Composite Provider – part 2 -execution

    Imagine this: For every interface IA you create: Your composite provider implements IA seamlessly In the constructor,pass an array of IA providers Each method returns the first successful value from your array of providers For even better performance,use a boolean flag to optimize by reusing previous successes The RSCG_CompositeProvider package doesnΓÇÖt just solve the obvious…

  • RSCG-Composite Provider – part 1 -idea

    API Outage solved with local data The problem that I try to solve is : How an UI can have data to show,even if the API from where it gathers data does not work ? Imagine having a robust system that adaptively switches between retrieving data from multiple sources – including internal APIs,memory-based storage,or even…

  • Pattern: CompositeProvider

    Description Composite Provider pattern is a structural design pattern that lets you compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly. Example in .NET : CompositeProvider And his usage Learn More Source Code for Microsoft implementation of CompositeProvider SourceCode Composite Provider Learn More File…

  • What I have learned by building .NET Stars -part 4- Keyed Dependency Injection – constructor by keys

    As I said before,I have constructed first the interfaces. Then I have a null object pattern for each interface,constructed automatically with a Roslyn Code Generator,https://www.nuget.org/packages/rscg_Interface_to_null_object . And now,what I want is to have keyed DI for each new implementation -with a twist: It’s like a game of matching keys when another class is injected,the first…
