It bothers me. A fix would be nice

Repro Steps & Context

dotnet restore and dotnet publish can produce different contents in $(IntermediateOutputPath)*.nuget.g.targets.

I'd love to know why, and what can be done to fix it.

The setup:

1. Run on macOS. (I haven't tested elsewhere.)

2. Install Uno Platform, VSCode

3. Create a new project:

   dotnet new unoapp -o unoapp -preset recommended
   

4. Initialize as a git repo:

   cd unoapp
   git init .
   git add .
   git commit -m 'dotnet new unoapp -o unoapp -preset recommended'

5. Cause unoapp/obj/unoapp.csproj.nuget.g.targets to be generated by both dotnet restore and dotnet publish at the "same" time:

   git clean -xdf ; 
   dotnet publish -c Release -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true &
   dotnet restore ; fg

   Make sure you copy and paste all the commands at once. We want the dotnet publish and dotnet restore commands to execute as close to the same time as possible.

   Interestingly, reversing the order -- dotnet restore & dotnet publish … -- doesn't result in build errors (as often?).

If you're "lucky", the build will fail ¹:

$HOME/.nuget/packages/microsoft.dotnet.ilcompiler/10.0.5/build/Microsoft.NETCore.Native.Publish.targets(91,5): error MSB3030: Could not copy the file "bin/Release/net10.0-android/android-x64/native/unoapp.so" because it was not found.

The cause of the MSB3030 error is that the IlcCompile target doesn't exist (?!):

% dotnet build -v:diag msbuild.binlog > msbuild.binlog.txt
% grep '"IlcCompile"' msbuild.binlog.txt
                   The target "IlcCompile" listed in an AfterTargets attribute at "/usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/36.1.43/targets/Microsoft.Android.Sdk.NativeAOT.targets (205,7)" does not exist in the project, and will be ignored.

which is problematic, because it's the IlcCompile target which is responsible for creating unoapp.so…

If you don't run dotnet restore and dotnet publish at the "same" time, the build will reliably succeed.

Additionally, the contents of unoapp/obj/unoapp.csproj.nuget.g.targets changes between dotnet restore and dotnet publish:

git clean -xdf
dotnet restore
cp unoapp/obj/unoapp.csproj.nuget.g.targets restored.targets
dotnet publish -c Release -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true
cp unoapp/obj/unoapp.csproj.nuget.g.targets published.targets
diff -u restored.targets published.targets

Why does unoapp.csproj.nuget.g.targets differ between dotnet restore and dotnet publish? My assumption is that if the contents didn't change, my "same time" builds would be more reliable.

Why I care

Why do I care? Who would be "silly" enough to run dotnet restore and dotnet publish at the same time?

The probable answer is a VSCode extension. I haven't figured out which extension yet, but if I open the unoapp folder within VSCode, then in a separate Terminal run:

git clean -xdf ; dotnet publish …

it will very often fail, driving me bananas. My assumption is that some VSCode extension is also running dotnet restore when it detects that the directory has changed, resulting in "concurrent" dotnet restore and dotnet publish invocations.

dotnet restore and dotnet publish use different defaults for the Configuration property, Debug vs Release. Are there any conditions like this:

<PackageReference Include="SomePackage" Version="1.0.0" Condition="'$(Configuration)' == 'Debug'" />

You can test this out by running:
dotnet restore
then running
dotnet publish -c Debug

The .nuget.g.props and .nuget.g.targets should be the same.

NuGet restore does not support using Configuration as a condition for packages because there are different defaults for different entry points.

[jonpryor]

@jeffkl: thank you for taking the time to reply.

Given the diff between restored.targets and published.targets, I have to believe that some @(PackageReference)s are based on $(Configuration) or something, though I cannot as yet find where or why that would be happening. It conceptually explains the file differences.

The idea to use dotnet publish -c Debug is problematic, though, because that triggers different build failures, likely because trying a Debug build with Android NativeAOT is an unsupported "why would you do that?!" configuration:

% dotnet publish -c Debug -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true
    /usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/36.1.43/targets/Microsoft.Android.Sdk.NativeAOT.targets(178,5): error XAGNALLAS7009: 
      System.InvalidOperationException: Internal error: assembly '$HOME/.nuget/packages/uno.ui.hotdesign/1.18.60/tools/uno.ai.xamlgeneration.assets/Anthropic.SDK.dll' lacks RuntimeIdentifier metadata

That aside, it's still an interesting idea, the results of which only complicate things:

git clean -xdf
# *just* publish:
dotnet publish -c Debug -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true

while it fails, the above also results in a unoapp.csproj.nuget.g.targets which doesn't mention net10.0-browserwasm, but does mention uno.extensions.reactive.messaging and Uno.WinUI.DevServer.targets. It's a third set of unoapp.csproj.nuget.g.targets file contents!

I'm also starting to wonder if this is a "file contents" issue or "just" a "the file changed" issue. Consider concurrent Debug publish and restore:

git clean -xdf ; 
dotnet publish -c Debug -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true &
dotnet restore 
fg

This time we're trying dotnet publish -c Debug concurrently with doting restore, and it also fails with an MSB3030. (Surprisingly, to me, as I expected the above XAGNALLAS7009…)

The contents of unoapp/obj/unoapp.csproj.nuget.g.targets are identical between dotnet restore and dotnet publish -c Debug. As before, the IlcCompile target cannot be found.

@jeffkl : I'm not sure what to consider next. Concurrent restore + Debug Publish results in unchanged unoapp.csproj.nuget.g.targets when the build ends, and also a failing build.

I half suspect that dotnet publish computes unoapp.csproj.nuget.g.targets, writes it to disk, forgets what it computed, then reads unoapp.csproj.nuget.g.targets from-disk and uses that. This could explain a bit of non-determinism?

[baronfel]

@jonpryor this is going to get a bit into the weeds, but MSBuild has an XML cache that it uses during a single 'build request' lifetime. Within this lifetime, the first time an XML document is read it is entered in this cache and from then on any Import or reading of that file will use the same XML content.

This is why you have to do a 'separate restore' (which for MSbuild means adding /restore, NOT -t Restore to build invocations, which the dotnet CLI does for you in all cases except when you use --no-restore) - the 'separate restore' doesn't have the NuGet-generated .g.props and .g.targets files, but then the actual build invocation after the 'separate restore', which is a separate 'build request', does read the NuGet-generated files.

Concurrent build invocations like you describe could result in the generated props files being independently modified/deleted/cleared/read by those separate builds at times that result in the XML cache being corrupted for that build. This is why we highly, highly suggest that only one build be triggered in a workspace at a time - in fact we're working on designing features to automatically enforce that because of how disruptive it can be.

[jeffkl]

Can you run the following:

dotnet restore /p:Configuration=Debug /bl:debug.binlog

And then run

dotnet restore /p:Configuration=Release /bl:release.binlog

Then attach debug.binlog and release.binlog?

[jonpryor]

@jeffkl: attached: binlogs.zip

[jeffkl]

Okay I don't see any differences in Debug vs Release. Can you try running a publish that does not restore:

dotnet restore
dotnet publish --no-restore -c Release -r android-x64 -f net10.0-android -bl unoapp/unoapp.csproj -p:PublishAot=true

Maybe what's happening is the target framework is being passed as a command-line argument which makes that one restore only restore for a single framework.

[jonpryor]

@jeffkl: done. I assume you want the resulting msbuild.binlog, which is attached: msbuild.zip

1. It built without errors.

2. Which is bizarre, because:

   1. The resulting .apk does not contain unoapp.so, which it should!
   2. Yet it didn't error out with the originally mentioned MSB3030 (?!)
   3. dotnet build -v:diag msbuild.binlog still contains "The target "IlcCompile" listed in an AfterTargets…does not exist in the project, and will be ignored" and also doesn't have any match for Target "IlcCompile, i.e. the target doesn't exist and wasn't executed.
   4. dotnet build -v:diag msbuild.binlog also doesn't mention Microsoft.NETCore.Native.Publish.targets, which is where the MSB3030 came from, so I guess the lack of an MSB3030 makes sense now?
   5. Regardless, the resulting .apk is broken.

I cannot begin to hypothesize what happened here.

Maybe what's happening is the target framework is being passed as a command-line argument which makes that one restore only restore for a single framework.

I don't think that's exactly the case.

As per the original description, dotnet restore produces a unoapp.csproj.nuget.g.targets which contains <ImportGroup Condition blocks for:

• net10.0-android
• net10.0-browserwasm
• net10.0-desktop
• net10.0-ios

Compare to dotnet publish … (without --no-restore), which produces a unoapp.csproj.nuget.g.targets that:

1. Only mentions net10.0-android, net10.0-desktop, net10.0-ios, i.e. it lacks net10.0-browserwasm, and
2. As per original issue description, there are many "missing" <Import/>s within those <ImportGroup/>s.

This is not "unoapp.csproj.nuget.g.targets only contains a single target framework."

What I do know is that Uno.Sdk does "something" to produce Configuration-dependent *nuget.g.targets files. I don't understand what that mechanism is, much less what to look for; the "obvious" answer of "just git grep -i 'ImportGroup' doesn't find anything interesting; I'm not even certain that the <ImportGroup/> generation code is within Uno.Sdk. I just don't know what I'm looking for.

I look forward to that.

In the meantime, I want to re-emphasize that "concurrent dotnet invocations" is quasi-figurative: it's not that I am trying to concurrently run dotnet restore and dotnet publish. It's that some currently unknown VSCode extension I have installed is running dotnet restore while I am running git clean -xdf; dotnet publish …. So there are literally two dotnet commands occurring, but one of them I have little control over, aside from either (1) not using VSCode in my build tree, or (2) disabling all VSCode extensions. (Or (3), figuring out which VSCode extension is doing me wrong here, and burning it in fire.)

Hopefully your feature design takes this scenario into consideration.

[jonpryor]

Part of me is of the mind that if the unoapp.csproj.nuget.g.targets contents were identical between dotnet restore and dotnet publish, then I wouldn't have these build problems.

I do not know how to confirm or deny that idea.

My earlier comment does indicate that "identical unoapp.csproj.nuget.g.targets contents" won't be an immediate fix, because it doesn't work (right now).

That is at least (eventually? probably?) solvable, i.e. it should be possible to make dotnet restore; dotnet publish --no-restore … Do The Right Thing™, but I'd like to know if fixing this issue will actually help or not.

[jeffkl]

The Uno SDK contains a lot of very customized build logic, so I'm really struggling to debug it.

I think its normal for the output of restore to differ if you have a multi-targeting project and then you run dotnet publish -f <framework>. dotnet restore runs an implicit restore and if you specify a framework, then the output from that subsequent restore will think there's only one framework. Builds after that will probably fail in interesting ways since the restore assets only include a single framework.

I swear there's an issue somewhere about that problem, dotnet publish -f net10.0 causing later builds to fail. The workaround is to specify a property just for restore. This tells MSBuild to run restore with one set of properties and then run publish with the other properties (like TargetFramework).

dotnet publish -f net10.0 -r win-x64 -restoreProperty:Something=Nothing

[nkolev92]

Thanks for making progress in this investigation.

I was not able to find a duplicate either, and I feel like this is something that we've seen as an issue (self contained publishing needing it's own restore).

I found some related issues that are related by the fact that they are running self contained publish.

dotnet/sdk#36727
dotnet/sdk#35131
dotnet/sdk#21877
#11653
dotnet/sdk#47093

That being said, I'm really not sure what to do with this issue.

I think NuGet is doing the thing it's designed to do, so from that perspective it's expected, but the publish scenario discrepancy is not ideal.

To throw on top of that there's an additional SDK here.

To catch the exact discrepancy (the publish binlog has the same assets file as the release/debug), we'd want to compare the obj content between the build & publish.

but even then, that probably just tells us what was configured differently.
