Workshop Mobile Development - Patterns for reuse

partial class A

{

// Half of the implementation

}

partial class A

{

// The other half

}

A.cs A.extra.cs

partial class A

{

// Declare the method here

partial void DoSomethingEx();

public void DoSomething()

{

// Some shared logic

DoSomethingEx();

}

}

partial class A

{

// Provide the implementation here

partial void DoSomethingEx()

{

// Do something iOS specific

}

}Can be used from shared

logic

Leaves room for specific

implementation

Always private and returns

void
