MSBuild target Pack fails - System.IO.Compression 4.1.0 not found

[jp2masa]

I'm using .NET Core 2.0 Preview 2 (2.0.0-preview2-006497) and when running MSBuild (from the Visual Studio installation) with targets Restore and Pack the operation fails with the following error message:

C:\Program Files\dotnet\sdk\2.0.0-preview2-006497\Sdks\NuGet.Build.Tasks.Pack\build\NuGet.Build.Tasks.Pack.targets(141,5): error : Could not load file or assembly 'System.IO.Compression, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

The project is targeting netstandard1.5 and adding global.json with sdk version "1.0.4" works fine.

Are you invoking pack through msbuild or through the CLI?

[jp2masa]

MSBuild, from the Visual Studio installation folder.

May be related to dotnet/msbuild#2235, which adds a binding redirect for that assembly (so we should never try to load 4.1.0.0, only the version that we ship).

I'm using the latest Visual Studio Preview, which includes the latest MSBuild version, right? The latest release was 8 days ago and that fix was merged 14 days ago, so it should be working.

@jp2masa that change isn't in the latest public preview--it takes some time for changes in the MSBuild repo to flow into the VS release. You could try manually applying the msbuild.exe.config change on your machine to confirm that it's fixed by that problem, or wait for the next public preview.

I applied the change in MSBuild.exe.config, but it's still not finding the assembly. I confirmed the assembly signature of the System.IO.Compression.dll file in the MSBuild folder, and the signature is equal to the one being searched by MSBuild after the change.

What is strange is that using the same MSBuild with dotnet sdk 1.0.4 specified in global.json it works.
UPDATE: Changing to use dotnet sdk 1.0.4 doesn't work with the binding redirect, but it works without it.

Crosslinking to NuGet/Home#4290.

This seems to be fixed in the latest Visual Studio Preview version.
