Specky6 1.1.0

Specky6

Lightweight wrapper to assist injection, using attributes, using the built in DI model integrated in .NET 6 and up.

Required at builder.Services to add Specks

builder.Services.AddSpecks();

Examples (If you're familiar with .NET's built in injection then the naming here should be straight forward.)

Transient

Transient will inject a new instance for every request.

[Transient]
public class MyClass { ... }

// Equivalent to builder.Services.AddTransient<MyClass>();

[TransientAs(typeof(IMyClass))]
public class MyClass : IMyClass { ... }

// Equivalent to builder.Services.AddTransient<IMyClass, MyClass>();

Scoped

Scoped will inject a new instance for every session, typically, in a web app for example, this is each time the Http connection is reset.

[Scoped]
public class MyClass { ... }

// Equivalent to builder.Services.AddScoped<MyClass>();

[ScopedAs(typeof(IMyClass))]
public class MyClass : IMyClass { ... }  

// Equivalent to builder.Services.AddScoped<IMyClass, MyClass>();

Singleton

Singleton will inject a the same instance for the lifetime of the application.

[Scoped]
public class MyClass { ... }    

// Equivalent to builder.Services.AddSingleton<MyClass>();

[ScopedAs(typeof(IMyClass))]
public class MyClass : IMyClass { ... }

// Equivalent to builder.Services.AddSingleton<IMyClass, MyClass>();

Using Speck attributes across multiple projects / assemblies

In order to scan for specks across multiple assemblies you need to pass those assemblies to the AddSpecks method. Note: Don't forget to include the assembly you are working in, assuming you will have Specks there also.

builder.Services.AddSpecks(new []
{
    typeof(Program).Assembly,
    typeof(MyProject2.SomeNamespace.SomeType).Assembly,
    typeof(MyProject3.AnotherNamespace.IInterfaceForSomething).Assembly
});
