I'm developing a C sharp application in Visual Studio for Mac. I have it set up to be signed with a developer ID signature to get it notarized by Apple. But it's not working. Here are the steps. (1). Sign the code using Visual Studio for Mac. (2). However, this .app file will crash. (3). When I create a dmg and request notarization with the xcrun altool command, I get the following error. { tlogFormatVersion: 1, tjobId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, tstatus: Invalid, tstatusSummary: Archive contains critical validation errors, tstatusCode: 4000, tarchiveFilename: MyApp.dmg, tuploadDate: 2020-08-18T08:29:55Z, tsha256: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx, tticketContents: null, tissues: [ tt{ tttseverity: error, tttcode: null, tttpath: MyApp.dmg/MyApp.app/Contents/MonoBundle/SQLite.Interop.dll, tttmessage: The signature of the binary is invalid., tttdocUrl: null, tttarchitecture: x86_64 tt} t] } Even if this succeeds, it won't matter because it will crash...
