Hi Jason,

Thanks for posting in the community!
>From your description, you found that after you used a certain ADO.NET Data
Provider in your ASP.NET web application, there will occur the problem that
the aspnet_wp.exe process take 100% full cpu utilizaiton when make change
to web app or rebuild it , yes?

As for this problem, would you please provide some further info on your
develop environment, such as .net framework version, OS version, IIS
version,...

Also, are you sure that it is the Data Provider cause this problem, what
database are you using and what kind of dataprovider are you using? I've
searched some reference and found there does seems common issue with Oracle
Data Provider. So not sure what's your detailed condition. Also, have you
tried remove the Data Provider related code to see whether the problem
remains?

And here is anohter KB article discussing on a 100% cpu utilization after
ASP.NET appdomain reloaded:
#FIX: After an AppDomain Unload, the ASP.NET Worker Process Uses 100
Percent of the CPU
