Description
I have a pretty large project (roughly 100K LOC).
It successfully builds in both .net6 and .net7.
Since the third preview of .net8, I've been trying to compile it with .net8 (so basically, each month, I'd get the latest preview, and retry).
I always get this error:
C:\Program Files\dotnet\packs\Microsoft.NET.Runtime.WebAssembly.Sdk\8.0.0-rc.1.23419.4\Sdk\WasmApp.Native.targ
ets(681,5): error : Precompiling failed for D:\john\_...\obj\Any CPU\Release\net
8.0\wasm\for-publish\aot-in\aot-instances.dll with exit code 1. [D:\john\....net8.csproj]
Is there a way to at least understand the underlying error, and see if you can fix it?
The project is a webassembly project.
Note: the solution compiles and runs in .net8 in debug mode no AOT, and in Release mode no AOT.
Reproduction Steps
The csproj file:
<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">
<PropertyGroup>
<TargetFramework>net8.0</TargetFramework>
<NoXamlPreprocessor>True</NoXamlPreprocessor>
<OpenSilverType>4</OpenSilverType>
<PublishTrimmed>true</PublishTrimmed>
<!--
<RunAOTCompilation>true</RunAOTCompilation>
<AotAssemblies>True</AotAssemblies>
-->
<EmccInitialHeapSize>2147483648</EmccInitialHeapSize>
<MtouchUseLlvm>False</MtouchUseLlvm>
</PropertyGroup>
...
If I uncomment those 2 lines, I get the error:
The command line:
msbuild <proj>.net8.csproj -m -p:Configuration=Release /p:Platform="Any CPU" /p:DeployOnBuild=true;PublishProfile=.\Properties\PublishProfiles\FolderProfileAOT8.pubxml
