  Creating .sln usingthe CLI ■ Create the dotnet core project in your directory. – ‘dotnet new mvc’ ■ Create a new solution file in the directory (will default to dir name) – ‘dotnet new sln –n <soluton name> ■ Add the .csproj file into the .sln – ‘dotnet sln <project>.sln add <project>.csproj ■ Able to open up inVisual Studio IDE

  Dependency Injection ■ Providea way for objects and classes to be passed dependencies – Constructor Injection is commonly seen ■ Framework services injected into Startup Class – As well as application services.. ■ Dependency Injection intoViews

  Tag Helpers ■ Enableserver-side code to render elements in Razor files ■ Form tag helpers provide a robust way to facilitate the post back data – Can generate a hidden Request VerificationToken ■ Input tag helpers with attributes – Enforce certain input types through viewmodels ■ Cleaner and easier to read, edit and maintain.

  Decisions Decisions.. You shoulduse .NET Framework for your server application when: ■ Your application currently uses .NET Framework (recommendation is to extend instead of migrating) ■ You need to use third-party .NET libraries or NuGet packages not available for .NET Core. ■ You need to use .NET technologies that are not available for .NET Core. ■ You need to use a platform that doesn’t support .NETCore. You should use .NET Core for your server application when: ■ You have cross-platform needs. ■ You are targeting microservices. ■ You are using Docker containers. ■ You need high performance and scalable systems. ■ You need side by side of .NET versions by application.
