[Weird] HTTP/3 does not work after publishing app, but works on debug and release

[alexandrehtrb]

Description

Hello,

I have a weird bug, that my app can make HTTP/3 requests when running on debug or release, but, when the app is published, it cannot make such requests.
My app is an Avalonia desktop app in .NET 6.
This bug happens in both Linux and Windows versions of the app.

Reproduction Steps

1. Make a .NET 6 app with a HttpClient making HTTP/3 requests

2. The app's .csproj has:

<PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <DebugType>embedded</DebugType>
    <EnablePreviewFeatures>True</EnablePreviewFeatures>
    <EnableCompressionInSingleFile>True</EnableCompressionInSingleFile>
    <PublishReadyToRun>True</PublishReadyToRun>
  </PropertyGroup>
<ItemGroup>
  <RuntimeHostConfigurationOption Include="System.Net.SocketsHttpHandler.Http3Support" Value="true" />
</ItemGroup>

3. Publish this app like below:

dotnet publish ./src/Pororoca.Desktop/Pororoca.Desktop.csproj `
		--verbosity quiet `
		--nologo `
		--configuration Release `
		-p:PublishSingleFile=true `
		--self-contained true `
		--runtime "win-x64" `
		--output "./out/win-x64/"

Expected behavior

Should make HTTP/3 requests without problems, because it works with dotnet run, whether it is on Debug or Release configurations

Actual behavior

The following Exception is thrown:

System.Net.Http.HttpRequestException: Requesting HTTP version 3.0 with version policy RequestVersionExact while unable to establish HTTP/3 connection.
   at System.Net.Http.HttpConnectionPool.ThrowGetVersionException(HttpRequestMessage request, Int32 desiredVersion)
   at System.Net.Http.HttpConnectionPool.SendWithVersionDetectionAndRetryAsync(HttpRequestMessage request, Boolean async, Boolean doRequestAuth, CancellationToken cancellationToken)
   at System.Net.Http.RedirectHandler.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken)
   at System.Net.Http.DecompressionHandler.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken)
   at System.Net.Http.HttpClient.<SendAsync>g__Core|83_0(HttpRequestMessage request, HttpCompletionOption completionOption, CancellationTokenSource cts, Boolean disposeCts, CancellationTokenSource pendingRequestsCts, CancellationToken originalCancellationToken)
   at Pororoca.Infrastructure.Features.Requester.PororocaRequester.RequestAsync(IPororocaVariableResolver variableResolver, PororocaHttpRequest req, Boolean disableSslVerification, CancellationToken cancellationToken) in C:\Projetos\Pororoca\src\Pororoca.Infrastructure\Features\Requester\PororocaRequester.cs:line 37

Regression?

No response

Known Workarounds

No response

Configuration

Running on .NET 6, last app version was compiled with 6.0.403;
Bug confirmed on Linux x64 and Windows 11 x64

Other information

The URLs that I use for testing HTTP/3 are:

https://cloudflare-quic.com/

https://quic.aiortc.org/

The error happens with both of them...

This is very likely same issue as #73290
On Windows the workaround is to copy the msquic.dll file from the runtime install next to your application.
On Linux the msquic needs to be installed - @ManickaP @wfurt for more info.
