I have a Xamarin UWP application that I developed. I am able to sign the app on my PC and it runs well.
I am now trying to publish the application (create an MSIX) so that i can distribute it within my office.
I consistently get an error:
SignTool Error: SignedCode::Sign returned error: 0x800700C1
I have tried different cerificates: from my store, …TemporaryKey. I have tried using the same key for signing the app an for publishing, i have tried to mix them up. I still get the same error.
I tried using the SignTool manually in debug and this is what I get:
