What you want to do is called "Serializing" your object, and .Net has a few different ways to go about it. One is the XmlSerializer class in the System.Xml.Serialization namespace.

### Usage ###
Merge tracking is managed by the client and stored in a property ([svn:mergeinfo][1]).
To use merge tracking you just merge as usual but without the revision range:
svn merge trunkURL
The client will take care of reading the properties to see what revision(s) need to be merged in and then up... |
Keep away from the second approach, best bet would be the autoboxing if you're using java 1.5, anything earlier your first example would be best. |
The solution using the String method is not so good for a variety of reasons. Some are aesthetic reasons others are practical.
On a practical front more objects get created by the String version than the more normal form (as you have expressed in your first example).

I think the clear answer is yes, but depending on the domain you are referring to, it could be REALLY yes, or less so yes.

I think your question should read, "Can you over Architecture your application?"

IMHO, Firebug is going to be your best bet. It will tell you which file the style came from and you can click on the filename to be transported instantly to the relevant line in the file.

DVCS achieve better merges by tracking the parent revisions of merges. In Subversion, when you merge one branch into another, you lose information about where the merge originated from. In a DVCS like Bazaar or Git, the "merged" revision ends up with two parent revisions.

If you want to, for example, only use void methods without any arguments as event handlers for events of any type, you can compile expression trees to do that. This can be modified to accomodate other event handler types, but you'll have to map the event handler's parameters to the event's somehow.

If you think you're going to be IO/memory bound, I don't think partitioning is going to be helpful. As usual, benchmarking first will help you figure out the best direction. If you don't have spare servers with 64GB of memory kicking around, you can always ask your vendor for a 'demo unit'.

Yes, you can. As an example, if you find yourself creating Interfaces or abstract classes before you have two subtypes for them, then you're over-doing it.
