Cross-platform mobile development using C# and Xamarin Forms

One of my favorite professional activities is educating students on technical topics they’ve not yet encountered at the university.

Yesterday I gave a talk on cross-platform mobile development using C# and Xamarin for a group of students from NORD University in Bodø, Norway. The goal of the talk was to show how easy it is to create a cross-platform app using modern tools and give them a baseline from which they can create their own app.

New features in FermiContainer 1.1

FermiContainer gains features, but while doing so becomes even more simple. How is this possible? Let me tell you:

Automatic resolving of constructor arguments

Through constructor injection, the dependencies known to the container are automatically resolved. No attributes or XML configuration are needed.

[Test]
public void Register_EvenMoreComplexClass_CanBeResolved() {
  m_fermiContainer.Register<IEvenMoreComplex, EvenMoreComplex>();
  m_fermiContainer.Register<ICalculator, Calculator>();
  m_fermiContainer.Register<IComplex, ComplexClass>();
  m_fermiContainer.Register<ClassWithoutInterface>();

  var complexInstance = m_fermiContainer.Resolve<IEvenMoreComplex>();

  IsInstanceOf<IEvenMoreComplex>(complexInstance);
}

public interface ICalculator {}

public class Calculator : ICalculator {}

public interface IComplex {}

public class ComplexClass : IComplex {
  public ComplexClass(ICalculator calculator) {}
}

public interface IEvenMoreComplex {}

public class EvenMoreComplex : IEvenMoreComplex {
  public EvenMoreComplex(
    IComplex complex, I
    Calculator calculator, 
    ClassWithoutInterface classWithoutInterface) {}
}

public class ClassWithoutInterface {}>

Default container instance

var instance = FermiContainer.DefaultInstance;

IsInstanceOf<IFermiContainer>(instance);
Assert.AreSame(instance, FermiContainer.DefaultInstance);

Easier to extend

The Services dictionary is now protected so FermiContainer is easily extendable.

Better performance

C# expressions makes FermiContainer very performant.

Available as source through NuGet

PM> Install-Package FermiContainer.Sources
