Issue:

I followed the steps for using the .NET Core IL Linker as demonstrated on this page. I am trying to use it on this repo, but when I run the command dotnet publish -c Release -r osx-x64 I get the following error:

/Users/phil/.nuget/packages/illink.tasks/0.1.4-preview-906439/build/ILLink.Tasks.targets(198,5): error MSB4044: The "ComputeManagedAssemblies" task was not given a value for the required parameter "SdkAssemblies". [/Users/phil/git/dotnet-native-test/Native.Cli/Native.Cli.csproj]

I've tried Googling the message but haven't had any luck. Am I doing something wrong?

@sbomer can you take a look?

@phil-harmoniq, this is happening because your example project uses the Microsoft.DotNet.ILCompiler package together with the linker, and these two packages happen to define different tasks with the same name (ComputeManagedAssemblies). It looks like you're trying to use corert together with the linker, and I'm not surprised that this scenario isn't working. The linker was designed with .NET Core in mind, and it would take some thought to see how it could fit in with corert.

If you're interested in the linker independently of corert, I'd suggest trying it on a .NET Core project, without the ILCompiler package. Make sure to use the latest version available at https://dotnet.myget.org/feed/dotnet-core/package/nuget/ILLink.Tasks. :)

Thanks for the clarification!
