CoreCLR R2R (non-composite) fails to build in debug configuration

[matouskozak]

Android framework version

net11.0-android (Preview)

Affected platform version

11.0.100-preview.1.26071.101

Description

Cannot build CoreCLR R2R (non-composite) .NET sample app in debug configuration with the latest workloads crashes with

dotnet/arm64/packs/Microsoft.Android.Sdk.Darwin/36.1.99-ci.main.92/targets/Microsoft.Android.Sdk.AssemblyResolution.targets(198,5): error MSB4096: The item "obj/Debug/net11.0-android/android-arm64/NetAndroidDefault.pdb" in item list "ResolvedSymbols" does not define a value for metadata "DestinationSubPath".  In order to use this metadata, either qualify it by specifying %(ResolvedSymbols.DestinationSubPath), or ensure that all items in this list define a value for this metadata.

Steps to Reproduce

Install the latest workloads (the one used for this were)

{
    "microsoft.net.sdk.android": "36.1.99-ci.main.92/11.0.100-alpha.1",
    "microsoft.net.sdk.ios": "26.2.11301-ci.net11-0/11.0.100-alpha.1",
    "microsoft.net.sdk.maccatalyst": "26.2.11301-ci.net11-0/11.0.100-alpha.1",
    "microsoft.net.sdk.macos": "26.2.11301-ci.net11-0/11.0.100-alpha.1",
    "microsoft.net.sdk.maui": "11.0.0-ci.net11.26072.12/11.0.100-alpha.1",
    "microsoft.net.sdk.tvos": "26.2.11301-ci.net11-0/11.0.100-alpha.1"
}

Try building .NET android sample app with

--configuration Debug --runtime android-arm64 --framework net11.0-android /p:UseMonoRuntime=false /p:PublishReadyToRun=true /p:PublishReadyToRunComposite=false --self-contained /p:EnableWindowsTargeting=true

Did you find any workaround?

No other than use R2R-Composite.

Relevant log output

dotnet/arm64/packs/Microsoft.Android.Sdk.Darwin/36.1.99-ci.main.92/targets/Microsoft.Android.Sdk.AssemblyResolution.targets(198,5): error MSB4096: The item "obj/Debug/net11.0-android/android-arm64/NetAndroidDefault.pdb" in item list "ResolvedSymbols" does not define a value for metadata "DestinationSubPath".  In order to use this metadata, either qualify it by specifying %(ResolvedSymbols.DestinationSubPath), or ensure that all items in this list define a value for this metadata.

I don't think these two work together currently:

--configuration Debug -p:PublishReadyToRun=true

It actually would be significant refactoring to fix -- we don't run illink/trimmer-related targets at all in Debug builds.

Can you use Release mode instead for this?

For Debug mode, I would just use default settings.
