I'm having this warning while building my application:
Failed to read 'C:\Users\me\documents\visual studio 2017\Projects\Phoneword\Phoneword\Phoneword.Android\obj\Debug\android\assets\Mono.Android.dll' with debugging symbols. Retrying to load it without it.
I searched in the Internet but nothing worked for me.
Can you help me please?
Do you perhaps have a sample project demonstrating this behavior? What we are specifically after is the .csproj which contains the <DebugType> and <DebugSymbols> elements which can help us pinpoint this issue.
Secondly, can you please post your version information so we know what build you are on? In Visual Studio, you can go to Help->About Visual Studio and in Visual Studio for Mac, you can go to Visual Studio For Mac->About Visual Studio For Mac.
If you are currently on 7.1 as per your initial filed version, please ensure to update to the latest Stable version.
the project is the Xamarin Tutorial one.
These are the elements you mentioned:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">

Phoneword build output
This sounds weird to me.
Today the build succeed succesfully without any modification...
I really can't explain why.
Anyway the app runs on UWP but it doesen't on Android Emulator.
I attach the build output!
Well, today everything is working.
I swear I have not changed any parameter or code.
What can I say? Thanks a lot to all.
