link step is very long with vc++7

[steph]

Hi,
I have a vc++6 project I migrated to vc++7 .NET.
If I only migrate without using managed extension, link
step takes 8 seconds.
If I check "use manage extensions" in project properties,
link step takes 4 minutes.
I use incremental link.
Why such a difference?
Thanks
steph

The main reason probably is because when you use managed extensions we
cannot incrementally link. Apart from that link times for managed code are
significantly longer due to the handling of CLR meta data. But generally not
8 seconds to 4 minutes if you compare the speed of a full link. More in the
2x to 5x range.
