Add support for passing configuration from the MSBuild targets to our linker
steps using the linker's --custom-data option.
There are just two values being passed now, but this will grow significantly
over time as linker steps are implemented.
* [dotnet] Detect, compile and publish Info.plist into the app.
* Automatically detect any property lists in the root project directory, and
include them into the build.
* Introduce the existing build targets to detect and compile Info.plist into
the .NET build.
* Add documentation for default inclusion. This document will grow over time
as more file types are automatically included.
* Add some tests.
* [dotnet] Adjust default inclusion behavior.
* Use a single platform-specific variable to control all types of
platform-specific inclusions.
* [dotnet] Move the default inclusion to .targets instead of .props, so that .NET's default inclusion logic is already imported.
.NET sets EnableDefaultItems in their .targets: https://github.com/dotnet/sdk/blob/master/src/Tasks/Microsoft.NET.Build.Tasks/targets/Microsoft.NET.Sdk.DefaultItems.targets#L16
PublishTrimmed must be set before we import Microsoft.NET.Sdk, which means we
also have to move the computation of the project type to before we import
Microsoft.NET.Sdk, because we need to know the project type to determine
whether PublishTrimmed and SelfContained should be set to true (neither should
if we're building a class library or a binding project).
Inject logic into the Build target to start creating the app bundle:
* Make sure the pre-existing list of targets (CreateAppBundleDependsOn) to
create an app bundle is not evaluated.
* Create a new CreateAppBundleDependsOn variable that contains the new targets
we want to run to create the app bundle for net5.
* Call the built-in publishing targets to copy files to the publish directory
(ComputeFilesToPublish / CopyFilesToPublishDirectory).
* Add a target that rewrites the publish directory for assemblies and dylibs
to put them in the app bundle instead.
Also add another nuget source to get Mono's net5 runtime packs.
This makes the tests/dotnet/MySingleView test app:
* Compile managed code successfully, referencing Xamarin.iOS.dll.
* Resolve the correct targeting and runtime packs (aka Mono).
The compiled result is not put into an .app bundle as iOS expects, so the
result isn't actually executable.
Create the various NuGet packages to support .NET 5+. The packages are
currently empty (and not very useful), but the actual content will come later.
The current set of NuGet packages are (this list is duplicated for each
platform: iOS, tvOS, watchOS and macOS):
* Microsoft.iOS.Sdk: currently contains the basic MSBuild targets files for an
MSBuild Project SDK. Will eventually contain all the build logic. Might also
eventually contain other tools (mlaunch, bgen, etc.), but these might also
end up in a different package.
* Microsoft.iOS.Ref: will contain the Xamarin.iOS.dll reference assembly.
* Microsoft.iOS.Runtime.[RID]: will contain architecture-specific files
(libxamarin*.dylib, the Xamarin.iOS.dll implementation assembly, etc.):
The NuGets built on CI are automatically published to a NuGet feed.
The versioning for the NuGet packages required a few changes: OS bumps are now
changed in Make.versions instead of Make.config (this is explained in the
files themselves as well).
