| microsoft.public.dotnet.languages.csharp |
| I'm using "internal" to manage specific access, but it's a crude tool, and I often find myself wishing for a "friend" designation to give greater specificity to my code. I note that "friend" isn't a keyword, so I'm not hopeful here, but I'm also guessing I'm not alone in seeing the significant value of this. On a related note, it would be nice to be able to specify different levels of protection f... |
