That's a great question but may lead to quite a bit of discussion as the answers could be very varied. It depends on
- how much effort are you willing to put into this?

Yes, that works fine. If you install the Team Foundation Client from the TFS 2008 DVD on your VS machine, you can connect to both TFS 2005 and TFS 2008 servers.

Is WebRequest The Right C# Tool For Interacting With Websites? |
|c#| |
I'm writing a small tool in C# which will need to send and receive data to/from a website using POST and json formatting. I've never done anything like this before in C# (or any language really) so I'm struggling to find some useful information to get me started.
I've found some information on the WebRequest class ... |
Microsoft leave it to 3rd parties to fill in the gaps regarding missing controls in the toolbox. I imagine time and cost would feature in their rationale.

Instead of calling containsKey() it is faster just to call map.get and check if the returned value is null or not.
Integer count = map.get(word);
if(count == null){
count = 0;
}
map.put(word, count + 1);

The Java language always promotes arguments of arithmetic operators to int, long, float or double. So take the expression:
a + b
where a and b are of type byte. This is shorthand for:
(int)a + (int)b
This expression is of type int. It clearly makes sense to give an error when assigning an int value ... |
Depending on your needs, you can just have an options table that has a list identifier and a list value as the primary key.

If you don't mind using strings for the actual values, you can simply give each list a different list_id in value and populate a single table with :

We actually created entities to handle **simple** pick lists. We created a Lookup table, that holds all the available pick lists, and a LookupValue table that contains all the name/value records for the Lookup.
Works great for us when we need it to be **simple**. |
I've done this in two different ways:
1) unique tables per list
2) a master table for the list, with views to give specific ones
I tend to prefer the initial option as it makes updating lists easier (at least in my opinion). |

It appears that your usage of has_one :through is correct. The problem you're seeing has to do with saving objects.

Well, F# is based on OCaml and OCaml has a rather [extensive macro system][1]. Given the syntactic and semantic similarities of F# and OCaml you may be able to port over the Ocaml macro system to F#.
