Steps to reproduce

Use the following xproj/project.json that builds successfully on Windows using the Preview2 tooling:

https://github.com/onovotny/Preview3-migrate-bug/tree/master/backup

Then run dotnet migrate. The migrate itself is successful, but the result does not build.

Expected behavior

Everything that works in preview 2 should work in preview 3 and beyond.

Actual behavior

Multiple compile failures.

  1. TargetFrameworkIdentifier cannot be inferred. Even following the directions and adding https://github.com/onovotny/Preview3-migrate-bug/blob/master/MegaLib.csproj#L10-L14 manually, did not help.

  2. Lots of other compile errors for essentially a "File->New" project.

Environment data

dotnet --info output:
C:\dev\MegaLib\Preview3-migrate-bug [master ≡]> dotnet --info

@piotrpMSFT Any ideas here? This seems like basic stuff, but tons of errors, even after doing the manual property group.

I'm not so sure this is a migration issue.

Even creating a scratch, clean, project, I can't use the GuidAttribute type. This type is a little funny because it's contract lives in corefx but the implementation is in coreclr.

Digging in a bit deeper, it looks like the GuidAttribute contract was erroneously made available in netstandard1.0 and should have been netstandard1.1+. It was fixed in https://github.com/dotnet/corefx/issues/7869#issuecomment-214858689. Your project is targeting netstandard1.0, so the compilation failure is it cannot find the type.

Removing the netstandard1.0 from the target frameworks fixed it. Alternatively, you could remove it from the AssemblyInfo.cs.

even after removing the GuidAttribute from the assembly info, it still fails to build:

@onovotny did you try to git clean? it looks like there is a bunch of leftover state [also interesting to clean up I think... @srivatsn?] that is causing a bunch of targets to skip. I removed the Guid attribute on a clean clone and build succeeded for netcoreapp1.0 and 1.3. It failed for net45 because OS X.

Yes, no dice. It's failing on the Profile32 ones, the UAP10.0 one and the WP8 one:

It's failing on the Profile32 ones, the UAP10.0 one and the WP8 one:

@srivatsn AFAIK we do not support those profiles atop the .NET Core SDK at this point.

It works in the preview2 tooling and I would expect it to work by GA from a cross-compiling tooling perspective.

I see part of the issue...
When working with the profiles, the build tooling isn't auto-referencing all libraries in the profile like before. It needs to continue to do that. Instead, I had to add to get past the Profile32 issue and on to the next thing -- not recognizing UAP10.0 like it used to:

  <ItemGroup Condition=" '$(TargetFramework)' == 'portable46-win81+wpa81' ">
    <Reference Include="System" />
    <Reference Include="System.Runtime" />
    <Reference Include="System.Runtime.Extensions" />
    <Reference Include="System.Resources.ResourceManager" />
    <Reference Include="System.Core" />
    <Reference Include="Microsoft.CSharp" />
  </ItemGroup>

This is related to the following issues:

#477
#491
#492

I believe that addressing those three will fix this one as this project/migration hits all three of those issues.

All the remaining work here is in the SDK. Closing this issue.
