Code object is not signed at all System.ServiceModel.Web.dll

[Elinares-82]

Steps to Reproduce

1. Ported XF app to MAUI
2. Compile de app connected to a brand new Mac machine Macbook Air M1
3. Not compilation success since Code object is not signed at all with random .dll

Expected Behavior

Compile the app as we can do it with an old machine Macbook Pro Intel processor.

Actual Behavior

Not compile with the following error:

Environment

Windows machine connected to mac

All the certificates are in the KeyStore

Version information

Visual Studio 17.9.6
Macbook Air M1 2020 Sonoma 14.4.1 Xcode 15.2

I created a new MAUI solution and configured the app identifier and compile as expected and run the app in a physical phone and emulator as well.

This error happens if there's a Resources directory in the app bundle (see #20135).

It looks like these two items:

<ItemGroup>
  <EmbeddedResource Include="Resources\Configuration\appsettings.json">
    <LogicalName>appsettings.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
  <EmbeddedResource Include="Resources\Configuration\server.json">
    <LogicalName>server.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
</ItemGroup>

somehow ends up in the Resources/Configuration subdirectory, even though LogicalName is set to the correct value to avoid that.

I have two ideas to try:

1. Use forward slashes instead of backwards slashes:

<ItemGroup>
  <EmbeddedResource Include="Resources/Configuration/appsettings.json">
    <LogicalName>appsettings.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
  <EmbeddedResource Include="Resources/Configuration/server.json">
    <LogicalName>server.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
</ItemGroup>

2. Use BundleResource instead of EmbeddedResource:

<ItemGroup>
  <BundleResource Include="Resources\Configuration\appsettings.json">
    <LogicalName>appsettings.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
  <BundleResource Include="Resources\Configuration\server.json">
    <LogicalName>server.json</LogicalName>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
</ItemGroup>

Can you try either of these to see if they work?

Sure, I'll try this and let you know the results. however, this is not happening with the other old mac, may be is for the new M1, why this happens?

BundleResource 

Using the option 1 I got the same error. With the option 2 the app compiles well, however, does not run since the files server.json and appsettings.json are needed in the assembly. Also, the background color is not being displayed. I'm attaching another msbuild in case can help to provide more information.

Uploading msbuild.zip…

I moved the server and appsettings files outside of the Resources folder and apparently in compiling. however, when the app startup I go a new exception

Looks like the msbuild.zip didn't upload correctly, can you try again please?

The problem is that the CleverTapSDK doesn't do swizzling right.

They intercept calls to application:didRegisterForRemoteNotificationsWithDeviceToken:. In their interceptor method they do their stuff, before they call the original (your) application:didRegisterForRemoteNotificationsWithDeviceToken: implementation. An additional detail is that every Objective-C method takes an hidden argument, which is the selector of the called method. Their bug is that they call the original implementation with the selector of their interceptor implementation - this is typically not a problem for an Objective-C program (although it's wrong and certainly visible if you look for it), but for us it's paramount this hidden argument is correct, because we use the selector to find the managed method to call, and we won't find the managed method using their selector name (thus the exception).

[Elinares-82]

but for us it's paramount this hidden argument is correct, because we use the selector to find the managed method to call, and we won't find the managed method using their selector name (thus the exception).

So that I'm understanding is I have to report this to CleverTap team to fix it? My Question is why with the older Mac this is not happening?

I'll remove the CleverTap implementation and test again.

This is the repo of CleverTap in case you could check it up

I removed clevertap implementation and the app is running as expected with the brand-new MacBook air M1. The MacBook pro Intel compiles the app as well without any change, so I do not understand this different.

Correct.

I don't know; I'd need a test project that I can use to reproduce the behavior in order to figure this out.

Apparently CleverTap released a new version of their nuget and now it's working. But I got the error serval times even when I deleted bin, obj, mac build. But for some reason I was able to compile a run the app in the emulator. I'll try in a physical device.
