See Test:

public class ClassWithOpenGenericTaskReturn
{
    private readonly IOpenGenericTaskReturn _i;

    public ClassWithOpenGenericTaskReturn(IOpenGenericTaskReturn i)
    {
        _i = i;
    }

    public Task<T> Get<T>()
    {
        return _i.Get<T>();
    }
}

public interface IOpenGenericTaskReturn
{
    Task<T> Get<T>();
}
