What is new in ASP.net 2.0
few words.
Configuration Management and General Administration
Several new enhancements can be found in 2.0 that enable easier deployment, management and general operation of ASP.NET enabled servers. Configuration management APIs now give you the ability to read, update and even create web.config files.
You can finally precompile your application before deploying it. Previously you had to either hit each and every page so ASP.NET compiles your site, or you used some sort of a tool that basically ‘walked’ your site to ensure the pages have been compiled.
Performance
64-Bit support means ASP.NET can take advantage of the full memory address space on 64-bit cpu’s.
Caching has also been improved upon, now allowing the developer to set custom dependencies, post-cache substitution which improve your ability to custom your caching.Managing the cache is now even easier, with the ability to create ‘cache profiles’ and tweak a ‘cache configuration’. Basically what happens is that you create a cache profile which you can then use on your pages which allows you to manage caching on many pages by simply modifying your cache profile.
For increased scalability, you can now set ‘SQL cache invalidation’ and ‘disk output cache’. SQL Cache Invalidation will cache the data until the data actually changes at the database
level (as oppose to time based). Disk output cache will cache the data to disk (not only memory), thus allowing for more pages to be cached since you are not limited to your servers memory limit.
