问题
I have a Asp.Net Core MVC application running on Windows Server 2008 R2 with IIS. But every time I update this application, I need to manually stop the applicationPool in IIS, and restart the applicationPool after I finish updating the app. Otherwise it will tel me "the xxx.dll is in use by other progress".
Is there any way to make this process easier?

Finally I found my anwser:
I just need add a file named app_offline.htm to the IIS web root(not your project wwwroot folder).
due to this issue you may need try both App_Offline.htm or app_offline.htm .

Opening the web.config file in an editor and saving it will cause the web application to reload, even if you don't change anything. All DLLs should be replaceable, until a user hits the site, causing the web application to start again. I sometimes use that as a workaround.
A more full fledged solution would be to use Web Deploy, either through Visual Studio or by command line. This can take a litte while to set up, but offers more automation.

There is no way to hotswap in place DLL's.
Your best bet is to deploy to a new folder each time (For example a versioned folder), and change the website directory in IIS once you have fully copied your website onto the server.
