HI,
Welcome to asp.net forum.
Error 3 The "GetProjectProperties" task failed unexpectedly.
System.FormatException: String was not recognized as a valid Boolean.
I can hardly give precise troubleshooting according to the error message above, first you need make sure your asp.net application works fine before you deploy it to IIS. For this issue, I’d like to suggest you to enable the failed Request Tracing in
IIS, this will give us some hint on why a request has failed, and check log files in C:\inetpub\logs\FailedReqLogFiles.
Please let me know if there is anything that I can do to help.
Best regards,
Angie
