win-x64 publish with Core3 Preview and VS2019 results in ""CheckEmbeddedRootDescriptor" task was not given a value for the required parameter "AssemblyPath""

I have been trying to publish a plain dotnet new winforms app by following the steps here, but I end up with error: error MSB4044: The "CheckEmbeddedRootDescriptor" task was not given a value for the required parameter "AssemblyPath".

See attached image for the whole process.

I am running VS2019 Preview and have the following SDKs installed: https://www.screencast.com/t/29MbjIeY04

Any advice on how I can overcome this?

I've had exactly same error when I used ILLink.Tasks package, publish works fine without it. So it must be some problem with ILLink.Tasks, not winforms?

This error occurs if you add ILLink.Tasks to a fresh core 3.0 console app so I don't think this is specific to winforms.

@jeffschwMSFT @sbomer it looks like general ILLink.Tasks problem. Where do you track those bugs? Can we move this issue there as it is not WinForms specific

@OliaG Feel free to move it to https://github.com/mono/linker. This is happening because the linker hasn't been updated to work with the 3.0 SDK, which is something we're working on.

@OliaG I'm facing the same issue with a console app in .Net Core 3.0

Thanks

This issue is related to the SDK drifting slightly from our current state. Our goal in an upcoming preview for .NET Core 3.0 is to integrate into the SDK to help eliminate these sorts of issues.

@sbomer was this issue already addressed?

[sbomer]

Yes, this should be fixed in the 3.0 SDK with PublishTrimmed.
