When we got nhib.pdf today, we suddenly reported an exception caused by the Type Initial Value of "nhib.pdf. Cfg. Configuration ." .
Detailed exception information "System. IO. FileLoadException" exceptions occur in WebApplication1.dll, but are not processed in user code.
Other information: failed to Load file or assembly "log4net, Version = 1.2.10.0, Culture = neutral, PublicKeyToken = 1b44e1d1_115821" or one of its dependencies. The Assembly list definition found does not match the Assembly reference. (Exception from HRESULT: 0x80131040 )"
Note that log4net, Version = 1.2.10.0, is Version = 1.2.10.0
The specific exception message is displayed. Version = 1.2.10.0. I didn't pay attention to it at first. I wasted a few hours. Then I checked my log4net Version and decided to set it to 1.2.12.0. Okay, I just vomited blood. A version 1.2.10.0 is released online. The original version is replaced and the result is passed.
