out to attendees at the PDC in July. The .NET frameworks consists of two pa 8 o( U: Z( X5 Q' ?# l# ^ |" y. r9 L

s, like ATL, MFC, C runtime library, standard template library and so on. .N : ^( m$ B+ I% P2 aET programming is significantly easier than using any of these older technol 6 F6 m( i: m, U3 ]" G0 D
ogies. For this reason, I suspect many developers will move away from using 9 x! Q1 z# {4 {( B: ^$ athe older technologies. The older technologies can buy you performance howev 1 e, N8 Z# M" D5 g e
er; so, some people that are very concerned about this will stick with what' $ l9 e) ]3 z6 [3 f* j: k" [7 {* A$ Rs around. As for COM, developing components with .NET is orders of magnitude 5 Z2 D) U$ o6 _$ \4 L# I' u: O0 ?
easier and the interoperation between components pretty much happens for fr 0 I/ U- d% s( C0 w& U, R* v9 O" v8 {

Question #9 Why was the templates feature not carried over from C++ to C#? 6 Q+ H$ a4 q E6 J0 j j 5 [/ d; q: X8 x. M9 z
: b7 ]0 o6 u' m5 y, w Answer Again, this is more of a runtime issue than a C# issue. First, temp 4 a. _$ o' D1 R) X; }/ ilates are difficult to implement and Microsoft choose not to do the work for 6 h/ Z+ ^% j+ g& p z
Version 1 of the product. They may do templates or something similar in fut % V5 n E1 |& A5 T5 s
ure versions. Second, since the runtime is a multi-language runtime, introdu ' i# \3 Q( b/ v) k, T! I. B

4 M$ C/ ?8 t: H; s Answer The .NET runtime offers code access security, which allows an admin % {# M. h, H, X. m/ X7 k5 p
