Convert anonymous type to new C# 7 tuple type

Question

The new version of C# is there, with the useful new feature Tuple Types:

public IQueryable Query();

public (int id, string name) GetSomeIn         


        

Answer 1

While tuple literals are not currently supported in expression trees, it doesn't mean the ValueTuple type isn't. Just create it explicitly.

public (int id, string name) GetSomeInfo() =>
    Query()
        .Select(o => ValueTuple.Create(o.Id, o.Name))
        .First();
