Resolving COM references isn't (yet?) supported on core msbuild. In the meantime, does it work when you use msbuild from the developer command prompt?

e.g.

msbuild -r
dotnet run --no-build

[dasMulli]

cc @rainersigwald @dsplaisted @nguerrera is there a plan for resolving COM references from core msbuild?

[MiyamuraMiyako]

@dasMulli I run msbuild -r, but seems not use netcore3.0 sdk to build:

D:\HLST\更新程序\UpDateClient>dotnet --version
3.0.100-preview-009812

D:\HLST\更新程序\UpDateClient>msbuild -r

@AaronRobinsonMSFT is driving referencing-COM-from-Core. No full plan yet, but we're meeting today to talk about one.

[nguerrera]

I run msbuild -r, but seems not use netcore3.0 sdk to build:

This is due to https://blogs.msdn.microsoft.com/dotnet/2018/11/13/net-core-tooling-update-for-visual-studio-2017-version-15-9/

It is recommended to use Visual Studio 2019 Preview 1 with .NET Core 3.0 Preview 1.

[AaronRobinsonMSFT]

@MiyamuraMiyako Thanks for trying out this feature! You can find a sample with some details here.

[AaronRobinsonMSFT]

@jeffschwMSFT Anything special you want to do with this issue?

[jeffschwMSFT]

Let's mark this issue as a 3.0 scenario. As we get further in the design, we may be able to implement it as suggested, but we also may need to enable the scenario in a slightly different way.

[jeffschwMSFT]

@AaronRobinsonMSFT we should move this issue to coreclr, or link it to an existing issue.

[AaronRobinsonMSFT]

@rainersigwald Is this the correct repo to add an issue about making a COMReference in dotnet-sdk?

[rainersigwald]

I think most of the work for supporting COMReference would be in MSBuild so I'd file at https://github.com/Microsoft/msbuild/issues.

[MiyamuraMiyako]

It seems that my issue has caused a lot of discussion.
@AaronRobinsonMSFT Thanks, I will try it and keep track of this feature.

[karelz]

Is there anything still to track / route out of here? Or can we close this issue @AaronRobinsonMSFT?

[AaronRobinsonMSFT]

I think at this point, we can close this issue.
