…unit tests No idea why this started happening. Its probably a change in behaviour under Mono 4.4/.x version of xbuild. since it only effects items using the "LigicalName" meta data. But the result is we get things like this in the Resource.Designer.cs static int drawable/foo = 123456789; which is obviously a compilation problem for c#. So to fix we add some processing of the logical Name to replace any "invalid" path seperators with valid ones.

How did you reproduce the issue? Building xamarin-android? or HelloWorld? And is it on Windows? |

The `Mono.Posix` source has been extracted into the [mono/mono.posix repo][1], which is used to build the new [`Mono.Unix` NuGet package][2]. Update the xamarin/xamarin-android repo -- and various dependencies -- to use the `Mono.Unix` package instead of `Mono.Posix.NETStandard`. This includes the [`Xamarin.LibZipSharp` NuGet][3], as of dotnet/android-libzipsharp@cf5e33c6. `Mono.Unix` no longer uses the older `libMonoPosixHelper` dynamic library, replaced by a new `libMono.Unix` native library. Unfortunately, this change broke a number of tests since the `Mono.Unix.dll` assembly was no longer able to find its companion native shared library. While the `Mono.Posix.NETStandard` NuGet package provides the `libMonoPosixHelper` native library, in practice the *actual* `libMonoPosixHelper` that was used was the "system" library included with the system mono. `Mono.Unix`'s new native helper library, however, must be taken from the NuGet and both the Mono and dotnet runtimes must be told where to load the library from once a P/Invoke into `Mono.Unix` is encountered in managed code. The native library is copied from the NuGet to the referencing application's output directory and it should be loaded from there. This proved to be easy for the "legacy" Mono: a simple [`dllmap` configuration][4] and everything works as it should. With `dotnet` however, dllmap doesn't work. `dotnet` has instead a number of mechanisms to configure where the native libraries can be found (5 I think). Unfortunately, the mechanisms either require that a main executable of the application calls the APIs on entry (e.g. in the `Main()` method) or that a JSON configuration file is provided for the application, telling the runtime where the native libraries reside. In case of `Xamarin.Android.Build.Tasks` there is no main executable we can configure, since it works in the MSBuild context, providing tasks and utilities to build Xamarin.Android apps. In this instance, `dotnet` could be persuaded to find the libraries by calling one of the 5 APIs. The problem with this approach, however, is that this action would have to be performed at **every** possible entry point to the `Xamarin.Android.Build.Tasks` assembly, since any of them could be used as the first one. While certainly possible, it would be both fragile and an unnecessary maintenance burden. Instead, a simpler (albeit a bit kludgy) solution was chosen: the `src/Xamarin.Android.Build.Tasks` build process now takes care of generating a fat (multi-architecture) binary for macOS hosts (including `x86-64` and `arm64` architectures) using the `lipo` utility, then it copies the resulting binary to the same directory where `Xamarin.Android.Build.Tasks.dll` and `Mono.Unix.dll` live. The Linux shared library is also copied to the same location. The `dotnet` runtime is able to find and load shared libraries that are in the same directory as the assembly that needs them and everything works as expected.

No idea why this started happening. Its probably a change in
behaviour under Mono 4.4/.x version of xbuild. since it only
effects items using the "LogicalName" or "Link" meta data.
But the result is we get things like this in the Resource.Designer.cs
which is obviously a compilation problem for c#.
So to fix we add some processing of the metadata to replace
any "invalid" path seperators with valid ones.
