dotnet publish -c Release fail with <RunAOTCompilation>true</RunAOTCompilation> and <BlazorWebAssemblyLazyLoad

[aguacongas]

Description

If we want to compile a Blazor project with AOT and lazy loading the command dotnet publish -c Release fail with error :

error BLAZORSDK1001: Unable to find '[lazy load assembly name].dll' to be lazy loaded later. Confirm that project or package references are included and the reference is used in the project.

Reproduction Steps

• Create a blazor wasm project
• Create a razor class library project
• Add a project reference to for the razor class library project to the blazor wasm project
• Add a BlazorWebAssemblyLazyLoad instruction for the razor class library assembly in the blazor wasm project
• Add true in the blazor wasm project
• try to publish the blazor wasm project with dotnet publish -c Release

ex:

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <RunAOTCompilation>true</RunAOTCompilation>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="6.0.0-rc.2.21480.10" />
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="6.0.0-rc.2.21480.10" PrivateAssets="all" />
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.Authentication" Version="6.0.0-rc.2.21480.10" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\RazorClassLibrary\RazorClassLibrary.csproj" />
  </ItemGroup>

  <ItemGroup>
    <BlazorWebAssemblyLazyLoad Include="RazorClassLibrary.dll" />
  </ItemGroup>
  
</Project>

Expected behavior

The publish command should run without error

Actual behavior

The publish command fail with :

error BLAZORSDK1001: Unable to find '[razor class library name].dll' to be lazy loaded later. Confirm that project or package references are included and the reference is used in the project.

@radical it looks related to #60274. I have a binlog at "\prkrishn-foo\share\msbuild.binlog" in case it helps, but it's fairly trivial to reproduce this with a regular blazor-wasm app.

Publish runs twice

and in the first one a bunch of MSBuild properties aren't resolved which results in this error:

First publish:

^ Notice Resources is missing

Second publish:

The first one is kicked off by WasmNestedPublishApp. More worrying is that it's sufficient to have the tool installed (without required AOT compilation) to run in to this issue:

it looks related to #60274.

That one is failing with The command "emcc --version" exited with code 1., and seems unrelated.

This is my understanding of what's happening here:

1. For the nested publish, we essentially run Publish target, and then the wasm native targets run

2. during the Publish part of it:
   a. we get to ProcessPublishFilesForBlazor, which currently we skip for the nested publish case ($(WasmBuildingForNestedPublish))

   • and this target populates @(StaticWebAsset), when run

   b. Then we get to GeneratePublishBlazorBootJson, which fails because it doesn't have the StaticWebAssets correctly populated, and thus can't find the lazy loaded assembly

Please correct me if I didn't that right. I don't really understand the static web assets part.

• To fix this, I tried removing the condition on ProcessPublishFilesForBlazor so it would run for nested publish also.

  • but this causes the build to fail because @(WasmAssembliesToBundle) is empty

• That seems to be because ProcessPublishFilesForBlazor removes items from ResolveFileToPublish

  • which causes _GatherWasmFilesForPublish to fail as it depends on @(ResolvedFileToPublish) to populate @(WasmAssembliesToBundle)

If this line of thinking is correct, then maybe we can instead of @(StaticWebAsset):

- <WasmAssembliesToBundle Include="%(ResolvedFileToPublish.FullPath)" Exclude="@(_Exclude)" Condition="%(Extension) == '.dll'" />
+ <WasmAssembliesToBundle Include="%(StaticWebAsset.FullPath)" Exclude="@(_Exclude)" Condition="%(Extension) == '.dll'" />

I'm not sure if this is the correct fix or not. @javiercn thoughts?

Our blazorwasm tests fail with this though, because there are more than one dotnet*js files in the publish folder:

/Users/radical/dev/r3/artifacts/bin/Wasm.Build.Tests/net6.0-Release/browser-wasm/blz_aot_prj_file_Debug/bin/Debug/net6.0/publish/wwwroot/_framework/dotnet.6.0.0-rc.2.21470.23.bc68qmiu8q.js
/Users/radical/dev/r3/artifacts/bin/Wasm.Build.Tests/net6.0-Release/browser-wasm/blz_aot_prj_file_Debug/bin/Debug/net6.0/publish/wwwroot/_framework/dotnet.6.0.0-rc.2.21470.23.c0ti6blhkl.js

For future (7.0) work, the targets can be reworked a bit to reduce the amount of work we do in the nested publish, and better integrate it.

This is duplicate to this issue? dotnet/aspnetcore#37570

The linked issue has same issue but AOT is disabled. It is using wasm-tools.

Minimal example linked in the project if helpful.

[pranavkm]

@srpeirce the presence of the wasm-tools is sufficient to trigger the same code that appears as part of AOT.
