问题
In Visual Studio, I need to substitute a word with another, preserving the first character case. For example I need to subsitute "Bob" with "James" and "bob" with "james" at once, and I must avoid to replace partial matches like "ob" with "james" or "James".
This can be done e.g. in Notepad++ with find:"((b)|(B))ob", replace: "(?2j:?3J)ames"; unfortunately this does not work in Visual Studio (I'm using 2015). Is it possible to do this in Visual Studio? Thanks.

It is not possible with Visual Studio regex replace feature. Use Notepad++ with your current approach, or use separate regex replacements:
Search: \bBob\b
Replace: James
and then
Search: \bbob\b
Replace: james
Note that \b is a word boundary. If you need to replace all substrings regardless of whether Bob or bob are whole words, remove the \b from the patterns.
