  • 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 ? The Roslyn Source Code Generator will generate a constructor that calls the this constructor  and will assign fields needed. Let’s give an example : We wrote public partial…

  • DIForFunctions–what it does- part 4

    You can find a demo at https://github.com/ignatandrei/FunctionsDI/tree/main/src/FunctionsWithDI  – see TestCOnsoleAPP. But let’s write here also Generate (constructor) and functions calls similar with ASP.NET Core WebAPI ( [FromServices] will be provided by DI ) Also,verifies for null . Usage Reference into the csproj <ItemGroup> <PackageReference Include=”RSCG_FunctionsWithDI” Version=”2022.6.19.1605″ ReferenceOutputAssembly=”false” OutputItemType=”Analyzer” /> <PackageReference Include=”RSCG_FunctionsWithDI_Base” Version=”2022.6.19.1605″ /> </ItemGroup> Then…

  • DIForFunctions–NuGet- part3

    The important part now is to make public – that means NuGet and documentation,The NuGet is pretty simple – with dotnet pack and with GitHub Actions – in order to do automatically every time I modify the main. 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

    Looking at ASP.NET Core,there is a wonderful feature that  gives you thinking :  you can put in any action for a controller FromServices argument and the framework will complete from,well,services: : public ActionResult Test([FromServices] MyFunction What if  you can do the same with any function from any class ? It will be good,but … how …

  • app.Use vs Middleware–and scoped services

    When you want to use a fast middleware,you can use ( pun intended) app.Use( However,if you want to use some of scoped services,e.g. app.Use(async (context,next) => {     var st= app.Services.GetRequiredService<IServerTiming>(); //code } then it gives an error Cannot resolve scoped service  from root provider For this you should create  a scope: app.Use(async (context,next) => {    …

  • Services.Add => 2 NuGet

    If you make a NuGet package for ASP.NET Core  and you make an extension method that calls Services.AddWhatever in order to add a Sngleton / Scoped / Transient a IWhatever =>  Whatever implementation,please add IWhatever in a separate Nuget . Why ? Because not all ASP>NET Core projects are made of a single project –…

  • Passing from .NET 5 to .NET 6

    First,read the document here: Migrate from ASP.NET Core 5.0 to 6.0 | Microsoft Docs .\ So those were my steps ( fully compile after each step ): 1. Replace in csproj net5.0 with net6.0 <TargetFramework>net6.0</TargetFramework> 2.  Update all nugets reference to the latest version 3.  Add globals.cs with various usings 4. Add globals.cs . Mine…

  • Templating Roslyn Source Code Generators

    I want that,when I generate code with Roslyn,to have a template that I can easy modify to generate code . Also,I want to let the user ( the programmer,in this case) modify this template  – maybe he has better ideas than me. For reading from the RSCG,is pretty simple: Make as an embedded resource and…
