Original Readme
FunctionsDI
Generate (constructor) and functions calls similar with ASP.NET Core WebAPI ( [FromServices] will be provided by DI ) Also, verifies for null .
Usage 1 - generate constructors from methods
Reference into the csproj
<ItemGroup>
<PackageReference Include="RSCG_FunctionsWithDI" Version="2022.7.7.636" ReferenceOutputAssembly="false" OutputItemType="Analyzer" />
<PackageReference Include="RSCG_FunctionsWithDI_Base" Version="2022.7.7.636" />
</ItemGroup>
<PropertyGroup>
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)GeneratedX</CompilerGeneratedFilesOutputPath>
</PropertyGroup>
Then for every class you can write [FromServices]
using RSCG_FunctionsWithDI_Base;
//namespace if necessary
public partial class TestDIFunction
{
public bool TestMyFunc1([FromServices] TestDI1 t1, [FromServices] TestDI2 t2, int x, int y)
{
return true;
}
//more functions
}
generates the constructor with needed details
public partial class TestDIFunction
{
private TestDI1 _TestDI1;
private TestDI2 _TestDI2;
public TestDIFunction (TestDI1 _TestDI1,TestDI2 _TestDI2) //constructor generated with needed DI
{
this._TestDI1=_TestDI1;
this._TestDI2=_TestDI2;
} //end constructor
//making call to TestMyFunc1
public bool TestMyFunc1(int x,int y){
var t1 = this._TestDI1 ;
if(t1 == null) throw new ArgumentException(" service TestDI1 is null in TestDIFunction ");
var t2 = this._TestDI2 ;
if(t2 == null) throw new ArgumentException(" service TestDI2 is null in TestDIFunction ");
return TestMyFunc1(t1,t2,x,y);
}
so you can call
var test=serviceProvider.GetService<TestDIFunction>();
Console.WriteLine(test.TestMyFunc1(10,3)); // calling without the [FromServices] arguments
Usage 2 - generate constructors from fields / constructors
<ItemGroup>
<PackageReference Include="RSCG_FunctionsWithDI" Version="2022.7.7.636" ReferenceOutputAssembly="false" OutputItemType="Analyzer" />
<PackageReference Include="RSCG_FunctionsWithDI_Base" Version="2022.7.7.636" />
</ItemGroup>
<PropertyGroup>
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)GeneratedX</CompilerGeneratedFilesOutputPath>
</PropertyGroup>
Assuming this classes, that you want to keep a minimum of parameters constructors
public partial class TestDIFunctionAdvWithConstructor
{
[RSCG_FunctionsWithDI_Base.FromServices]
private TestDI1 NewTestDI1;
[RSCG_FunctionsWithDI_Base.FromServices]
public TestDI2 NewTestDI2 { get; set; }
public readonly TestDI3 myTestDI3;
private TestDIFunctionAdvWithConstructor(TestDI3 test)
{
myTestDI3= test;
}
}
public partial class TestDIFunctionAdvNoConstructor
{
[RSCG_FunctionsWithDI_Base.FromServices]
public TestDI1 NewTestDI1;
[RSCG_FunctionsWithDI_Base.FromServices]
private TestDI2 NewTestDI2 { get; set; }
}
the generator will generate
namespace TestFunctionsWithDI
{
public partial class TestDIFunctionAdvNoConstructor
{
public TestDIFunctionAdvNoConstructor( TestDI1 _NewTestDI1,TestDI2 _NewTestDI2 )
{
this.NewTestDI1 = _NewTestDI1;
this.NewTestDI2 = _NewTestDI2;
}//end constructor
}//class
}//namespace
namespace TestFunctionsWithDI
{
public partial class TestDIFunctionAdvWithConstructor
{
public TestDIFunctionAdvWithConstructor(TestDI3 test, TestDI1 _NewTestDI1, TestDI2 _NewTestDI2) : this (test)
{
this.NewTestDI1 = _NewTestDI1;
this.NewTestDI2 = _NewTestDI2;
}//end constructor
}//class
}//namespace
Enjoy!

This is the use of RSCG_FunctionsWithDI in Program.cs
// See https://aka.ms/new-console-template for more information
using Microsoft.Extensions.DependencyInjection;
using RSCG_FunctionsWithDIDemo;
var services = new ServiceCollection();
services.AddSingleton<TestDIMyClass>();

var serviceProvider = services.BuildServiceProvider();
var test = serviceProvider.GetRequiredService<TestDIMyClass>();
Console.WriteLine("the TestMyFunc1 is not called with [FromServices] parameters " +test.TestMyFunc1(10, 3));
This is the use of RSCG_FunctionsWithDI in TestDI1.cs
namespace RSCG_FunctionsWithDIDemo;
public class TestDI1
{
public int x;
}
This is the use of RSCG_FunctionsWithDI in TestDI2.cs

}
This is the use of RSCG_FunctionsWithDI in TestDIMyClass.cs
using RSCG_FunctionsWithDI_Base;
namespace RSCG_FunctionsWithDIDemo;
public partial class TestDIMyClass
{
public bool TestMyFunc1([FromServices] TestDI1 t1, [FromServices] TestDI2 t2, int x, int y)
{
return true;
