How can I write a generic anonymous method?

Question

Specifically, I want to write this:

public Func, T> SelectElement = list => list.First();

But I get a syntax error

    public static void SomeContainerFunction()
    {
        const string NULL_VALUE = (string)null;

        Type GetValueType(T value) => value?.GetType() ?? typeof(T);

        var typeOfNullValue = GetValueType(NULL_VALUE);

        Debug.WriteLine($"Value: {NULL_VALUE}, Type: {typeOfNullValue}");
    }
