Need not to be.
I am reading a book and there is one sentence I would have written differently, and it surprises me to be good English. It probably is though. My question is, is this common English:
1. The choice between WPF and Silverlight need not to be mutually exclusive.
I would have written this sentence as:
2. The choice between WPF and Silverlight does not have to be mutually exclusive.
or perhaps, but I think my first sentence is better, I would write:
3. The choice between WPF and Silverlight doesn't need to be mutually exclusive.
Are sentences 2 and 3 correct English too, or should I use constructions like 1?
For your interest, WPF and Silverlight are software programming tools.Ah!!! I have not copied the first sentence correctly. In the book it says:
1. The choice between WPF and Silverlight need not be mutually exclusive.
