.NET Core SDK 3.1.111 ASP.NET Core targeting pack files are newer in .exe installer than .zip package

[@NicoleWang001 dotnet/runtime#3756 (comment)]
With SDK 3.1.107 and 3.1.401, ref files (files on .\packs\Microsoft.AspNetCore.App.Ref\3.1.3\ref\netcoreapp3.1) on .exe installer is more recent than .zip installer.

[...] Still repro on SDK 3.1.111, ref files (files on .\packs\microsoft.aspnetcore.app.ref\3.1.10\ref\netcoreapp3.1) on .exe installer is more recent than .zip installer.

Transfered from from dotnet/runtime#3756.

Also repro on net 5 RTM x86 SDK(5.0.100-rtm.20526.5), will track this bug also.

It appears the contents of the msi and nupkg for the targeting pack are different which they shouldn't be.

@dagood thanks for the report.

@dotnet/aspnet-build do you have any thoughts?

[wtgodbe]

Huh, interesting - I'll take a look

[wtgodbe]

The reason, at least for us, is that the .nupkg input files are from the various project output directories, while the .zip input files are from a centralized location where we copy all of those project output files to create a layout. So, it's the same set of files, but the ones in the .zip have been copied one extra time.

@dagood does this still sound like an issue, given the above?

[dagood]

I'm not sure what the issue is, I just moved it here from a thread in dotnet/runtime. 😄
@NicoleWang001 and @vdanche may be able to provide more context.

@dagood The issue is that .NET SDK installers have different contents as the zip archives, e.g. With SDK 3.1.405, ref files (files on .\packs\Microsoft.AspNetCore.App.Ref\3.1.10\ref\netcoreapp3.1) on .zip installer is more recent than .exe installer.

Repro steps:

1. Installing the .NET Core SDK 3.1.405(Use release/3.1.4XX branch from https://github.com/dotnet/core-sdk)
2. Downloading and extracting the zip archive of the .NET Core SDK
3. Running a folder diff on the extracted SDK and the install folder
   Tool WinDiff : \bvtsrv2\Team\v-yunwei\Docshare\windiff

Expected Result:
The installers include identical contents as the zip archives

Actual Result:
.NET SDK installers have different contents as the zip archives, ref files (files on .\packs\Microsoft.AspNetCore.App.Ref\3.1.10\ref\netcoreapp3.1) on .zip installer is more recent than .exe installer.

This is not an issue - the files are the same, the reason that the last-modified stamp is different is because the files in the .zip were copied from their original location to a layout folder. @NicoleWang001 was this caught by a CTI validation scenario? If so, can we modify that validation scenario so that we check for FileVersion rather than for the last modified date?

[vdanche]

@wtgodbe Got it! We'll make note in our test scenario. Thanks much!
