Cause

The SystemTempAndTMPVariables point to a folder that does not exist. The Compiler generates temporary files in the folder whereTempAndTMPVariables point to before the files are copied to the temporary ASP. net Files folder. however, the folder where the system variables point to is deleted when you restart the computer. therefore, the compiler cannot generate the temporary files.
