I have been following this guide on setting up free device provisioning for iOS apps in Xamarin, however Visual Studio never seems to locate a provisioning profile.

I get through all the XCode steps without issue, even deploy the blank XCode project to my iPhone without issue.

When I get to step 8 of the "Deploy your Xamarin.iOS app" section however (the Visual Studio tab), the signing identity doesn't exist, nor does the provisioning profile (see the below image).

If I attempt to run my application the output window does show it found the correct profile and certificate:

1> Code Signing Key: "Apple Development: [Redacted personal email] (A248A6WF6F)" (B30BFAAA304EE99F25656BDA0095A97BA3104EDF)
1> Provisioning Profile: "iOS Team Provisioning Profile: com.companyname.mytestapp1" (c38b8ce4-f892-440f-991e-17287768105b)
1> Bundle Id: com.companyname.mytestapp1
1> App Id: BG3U7QRUKM.com.companyname.mytestapp1

But then the deploy fails with the following output:

ApplicationVerificationFailed: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.aEefsk/extracted/mytestapp1.iOS.app : 0xe8008015 (A valid provisioning profile for this executable was not found.)

And my error window shows:

Error error MT1006: Could not install the application '/Users/matt/Library/Caches/Xamarin/mtbs/builds/mytestapp1.iOS/e472585bbe370a429acd1bb065d6b3f2ebe6b76f1907d868be01a91463b888f9/bin/iPhone/Debug/device-builds/iphone12.1-15.2/mytestapp1.iOS.app' on the device 'Matt???s iPhone': AMDeviceSecureInstallApplicationBundle returned: 0xe8008015.

I've hit a wall on getting this working and hope you lot can give me something to work with. I can export the certificate as a .p12 file from XCode, but I haven't found any way to import that into Visual Studio. It's also worth noting that Visual Studio is on a Windows PC, then I have a MacBook as my build host, and the iOS device is connected to the MacBook via USB.
