Remember that the Windows log module DLL C:\Windows\system32\inetsrv\aspnetcore.dll failed to load once in a row. The returned data is an error message.

This error is in my local development environment, not the production environment, if it is the production environment I hung up .... Development environment also painful ah, re-install the system, I estimate the installation system + all software, less say also have 1 days ....

Error Generation: Reinstall IIS (there is always a small problem with IIS, install Microsoft IIS7 Rewrite module, each time you click on the blank rule, you will be prompted to make changes are lost, to save the changes?) whether I click Cancel or OK, the IIS panel closes, Because of a third-party rewrite module that has been used before, can not be divided into site rewrite, now two sites of the same path can not be rewritten, who knows the question who in passing reply me. )

After reloading IIS, regardless of which Web site you visit, the IIS process is immediately terminated and then prompted for service unavailable ....

All kinds of Baidu no fruit, but found csdn have a problem and I like to see links http://bbs.csdn.net/topics/392024907?page=1

Later only to know, belong to the same kind of problem.

I followed the discussion of the post, and then the two of my native rewrite have been deleted, removed the rewrite module and the Isapi_rewrite3 software

Found or useless, and then run StackOverflow on the search C:\Windows\system32\inetsrv\aspnetcore.dll this (the post also mentions a link estimate is also this, because the feeling may have more results on their own search directly)

After searching for the first answer (I am also drunk, open this link at least a few minutes) .... Big Celestial can only block google.com related domain name, technical class do not block, StackOverflow some JS quoted some of Google's domain name is blocked hard to open. )

And then look at the answer

Then I directly do not repair, directly uninstalled the. NET core ....

The third answer: (If you are not a good production environment uninstall just said that plan, temporarily can use this method to try, I did not test do not know the line. )

No wonder the Csdn man said he reinstalled the IIS rewrite module. So if you've found this problem, think about what software you've installed ... Keep a record of your reminders. The egg hurts.

There is the article at the beginning of the question that I do not know who has encountered no, some trouble to inform. Thank you
