Broken reference to .NET Standard 2.1 library in .NET Core 3.0 preview 6 #2878

Broken reference to .NET Standard 2.1 library in .NET Core 3.0 preview 6

After upgrading to .NET Core 3.0 preview 6, .NET Core 3.0 apps cannot use .NET Standard 2.1 libraries anymore.

General

For example, see https://github.com/hez2010/HLib. It won't build if I upgrade to .NET Standard 2.1. Works fine on .NET Standard 2.0.

@joperezr @ericstj can you please advice where to route it?

ericstj commented 5 years ago

I was unable to reproduce any problem.

Can you share more information about what sort of failure you are seeing?

Do things like provide the dotnet --info output, and the error you are seeing.

joperezr commented 5 years ago

If this is a build-time failure that you are seeing, then can you please also attach a binlog file? to produce one, simply run the following on a developer command prompt: msbuild yourProject.csproj /t:rebuild /bl which will generate a msbuild.binlog file.

If this is a runtime failure, do you mind sharing either exact repro steps or at least failure/call stack details?

hez2010 commented 5 years ago

It works while using .NET Core cl tools, but if you use MSBuild, it will fail.

joperezr commented 5 years ago

This is a wierd one, seems to be a problem with the sdk where it isn't copying metadata of transitive framework references. This is not something I'm super familiar with, @dsplaisted do you mind taking a look? It is very weird that this works fine when building with the CLI but doesn't work with MSBuild given that MSBuild still seems to be using the SDK. @hez2010 just wondering, have you tried updating your VS 2019 to the very latest preview?

dsplaisted commented 5 years ago

This looks like this bug, which should be fixed in the latest VS preview.

There is also a workaround here

joperezr commented 5 years ago

Given that there is a workaround and that the issue is fixed in latest version, I'll go ahead and close this one for now. @hez2010 if this still repros even after the workaround or updating VS, then please reopen and we will investigate further.

ralmsdeveloper commented 5 years ago

@joperezr I have the same problem with the most up-to-date version of VS 2019 Enterprise

ericstj commented 5 years ago

@ralmsdeveloper did you see the details in https://github.com/dotnet/cli/issues/11378? Did you install the latest Preview6 SDK?

ralmsdeveloper commented 5 years ago

@ericstj,

I've tried, but it does not work, I'm with VS2019 Enterprise and also the preview version, both do not work! See the complete log. https://github.com/aspnet/EntityFrameworkCore/issues/16230

mc0re commented 4 years ago

November 2019, I still cannot use a .NET Standard 2.1 library from a .NET Core 3 project... The workaround allows compiling the solution, but the IntelliSense still complains.

dsplaisted commented 4 years ago

@mc0re We are not aware of any issues with this in the 3.0.100 .NET Core SDK. If you are hitting this, please file a new issue with the details. Thanks!
