What exactly is the requirement to create a company internal App with Xamarin.Forms UWP? I can compile the *.appxbundle-Package but nobody can install it because of an certificate error. If I try to use our normal code signing certificate from StartSSL to sign the package, I got the following error:
`The Manifest Designer could not import the certificate.
The certificate you selected is not valid for signing because it is either expired or has another issue. For more information, see: https://go.microsoft.com/fwlink/?LinkID=241478`
The same certificate is used by our other desktop application with the signtool, so I guess the certificate is ok. Usage of the signtool for other .NET assemblies such as WPF projects:
"C:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe" sign /f "..\..\..\..\..\Finaltec\Framework\Signing.pfx" /p ... /tr "http://timestamp.globalsign.com/scripts/timestamp.dll" "$(TargetPath)"
Are there any special requirements to sign a UWP app so anyone can install it? The used certificate is a Class 3 StartSSL Code Signing Certificate and it is valid until Junuary 2020. If I try to install the app with the generated test certificate from the Visual Studio, I got the message that the root certificate is not trusted and the installation process will be canceled. Even if I install the certificate manual before I got the same result error.
