Indexers

public object this[string key] => dictionary[key];

Is equivalent to:

public object this[string key]
{
get
{
return dictionary[key];
}
}

Methods

static int Multiply(int a, int b) => a * b;

Is equivalent to:

static int Multiply(int a, int b)
{
return a * b;
}

Which can also be used with void methods:

public void Dispose() => resource?.Dispose();

An override of ToString could be added to the Pair<T> class:

public override string ToString() => $"{First}, {Second}";

Additionally, this simplistic approach works with the override keyword:

public class Foo
{
public int Bar { get; }

public string override ToString() => $"Bar: {Bar}";
}
