In. net2.0 ,. net 3.5 uses the same CLR, so. machine in net2.0. config can run in. net 3.5, and you only need to install the new Framework and update the assemblies. The risk is not avoided. I will rewrite the custom part settings for machine. Conifg of the original. net 2.0. We have not registered new tags, handlers and modules. So you only need to install a new Framework to run New Features of. Net3.0 and. net3.5.

The second part is to specify whether to use ASP. NET HttpModules to control URL requests of all ASP. NET Applications When ASP. NET applications are running in IIS 7. We authorize by default. That is to say, by default, the system is compatible with IIS 7 and uses URL requests in IIS 7 for control. ASP. net urls modules will be configured in Machine. config.

(3) Multi-file configuration of Web. config

In fact, the new. net 4.0, a new application pool ASP. NET V4, so that at least two ASP.. NET.
