Let's be clear about what you're saying here - TFS is free up to 5 developers until you have to purchase a support contract from some TFS consultant to figure out how to make it work.

"You should use TFS" - a TFS consultant

There is a chance that it's bad! e.g.
code:
class C {
   public string s {get; set;}
   public override int GetHashCode() {return s==null ? 0 : s.GetHashCode();}
}
This is bad because if ever the string changes while an instance of "C" is inside the HashSet, then it will be in there under the previous has-code rather than the new one.

The general rule is: only compute GetHashCode from fields/properties that are guaranteed not to change after construction, e.g. because they have the readonly modifier

The better rule is don't use mutable values as keys to a hashmap. The even better rule is don't use mutable values.
