When I was working on a project today, the error "error: ASP. NET Ajax client framework could not be loaded" was prompted when I was just running the project, and an error was reported consecutively:
Even more irritating is that it runs normally on other machines. As a result, Google immediately obtained a solution:
- "Extension ing" in IIS. Someone pointed out that this problem occurs if the script ing in IIS is not. axd. It has been verified that this is not the case.
- UTF-8 encoding problems. <Globalization requestencoding = "UTF-8" responseencoding = "UTF-8"/>. The page encoding format is UTF-8. Invalid. It does not seem to be a coding problem.
- Debugging mode problems. Modify <compilation DEBUG = "true"> In webconfig to false. Invalid.
- Add system. Web. Extensions and System. Web. Extensions. Design references to the project. It's useless.
- Reinstall microsft.net framwork 3.5 SP1 to fix the environment. Solve the problem.
