Visual Studio Code – Blazor Hybrid – iOS debug – Microsft.CSharp.dll not signed

I’m building an app on Blazor MAUI.

Android works fine (Debug and release).
I pushed the code on my local mac device for debugging. Same Visual Studio version.
When working on iOS, I face an issue where the "debug" mode to my iPAD seems to return a "Failed to Codesign" error.

Here’s the errors:

/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk/16.4.7089/tools/msbuild/iOS/Xamarin.Shared.targets(3,3): Error: /usr/bin/codesign exited with code 1:
/Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app: code object is not signed at all
In subcomponent: /Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app/Microsoft.CSharp.dll (AppName)

Below another error which seems to be linked to the Failed to codesign

Failed To codesign 
/Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app: code object is not signed at all
In subcomponent: /Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app/Microsoft.CSharp.dll (AppName)

The app seems to build on MacOS (have a crash due to incompatibility of packages, but that’s not what I’m afraid of).
It just doesn’t want to build on my local iOS Device.
When I try to build using the iossimulator it has the same error.

Here’s my property group for ios:

    <PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|net7.0-ios|AnyCPU'">
      <CodesignProvision>Codesign Provision</CodesignProvision>
      <CodesignKey>CodeSign Key (FAKEKEY32)</CodesignKey>
      <CreatePackage>false</CreatePackage>
    </PropertyGroup>

I tried :

  • Removing the false
  • Adding some extra arguments under the
    -${ProjectDir} hasn’t changed anything
    -Most of the others ${} options basically crash the whole thing with a new error message

    • Adding the /Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app/ change the problem to System.Web.dll (which is under AppName.app as well)
    • Adding the actual /Users/userName/Documents/GitHub/doc/AppName/bin/Debug/net7.0-ios/ios-arm64/AppName.app/Microsoft.CSharp.dll returns an errSecInternalComponent due to unable to build chain to self-signed root for signer xxxx
    • I tried to create a new set of credentials to sign & changed from general App Development to IOS development

I saw this subject but it doesn’t seem to solve the problem

    So I found a solution for my problem.

    Deleting everything and made sure that all reference to any resource was mentioned once (even with the tag).

    I had, for example, some resources mentioned twice in the .csproj file : Once on the ResourcesImages* and once as a standalone like ResourcesImagesMyImage.png (That was a rest of something I was playing with when starting the app).

    Now it's working fine.

    Found the solution looking at : https://github.com/dotnet/maui/issues/15144

    I don’t know if you already fixed this issue. In my case the problem were two folders. First of all the Properties folder which contained CultureRecources in my case and a folder which contained .png Pictures and dome additional .dll files. After I removed them everything was working fine. Currently I search for a way to use at least everything in the properties folder. When I find a solution I will add it to this post.
