The ASP. NET Ajax client framework cannot be loaded.

The ASP. NET Ajax client framework cannot be loaded.

I found several issues on the Internet that refer to UTF-8,

Generally, when I build a website, I directly set it to UTF-8 for pulling. However, this problem also occurs to me. I don't need to use it when I restart the machine.

I think it must be a problem with Web. config. I changed the new one and copied the custom and service settings to the zone.

However, after a while, something went wrong. Oh, I modified <compilation DEBUG = "true"> in config.

Then I changed it to false. refresh it and load it normally. I am modifying it back. The ASP. NET Ajax client framework cannot be loaded. Finally, I figured out the problem, which is prone to errors during debugging, but not very often, because I usually use DEBUG = true until the end of development, and occasionally this problem occurs,

So if you still see that the ASP. NET Ajax client framework cannot be loaded, check out. I think debug may be the culprit.
