.NET core app does not start when published with `/p:PublishSingleFile=true`

See original GitHub issue

How can I use publishing of single-file executables?

I tried to follow the instructions from https://docs.microsoft.com/en-us/dotnet/core/whats-new/dotnet-core-3-0#single-file-executables, but this did not work:

Steps to reproduce

dotnet publish -r win10-x64 /p:PublishSingleFile=true

The publish command produced following output in the console:

Microsoft (R) Build Engine version 16.3.0+0f4c62fea for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

  Restore completed in 85,07 ms for K:\Source\Repos\bots\implement\engine\BotEngine.Windows.Console\BotEngine.Windows.Console.csproj.
  BotEngine.Windows.Console -> K:\Source\Repos\bots\implement\engine\BotEngine.Windows.Console\bin\Debug\netcoreapp3.0\win10-x64\BotEngine.dll
  BotEngine.Windows.Console -> K:\Source\Repos\bots\implement\engine\BotEngine.Windows.Console\bin\Debug\netcoreapp3.0\win10-x64\publish\
  • Run the published app on the same machine, by entering the following command in powershell: ./botengine

Expected behavior

I expected the single-file executable app to behave the same way as when published without the /p:PublishSingleFile=true option. When published without the /p:PublishSingleFile=true option, the apps output starts as follows:

Please specify a subcommand.
BotEngine console version 2019-09-01
[...]

Actual behavior

When trying to start the app, it outputs the following message:

Error:
  An assembly specified in the application dependencies manifest (BotEngine.deps.json) was not found:
    package: 'LibGit2Sharp.NativeBinaries', version: '2.0.267'
    path: 'runtimes/win-x64/native/git2-572e4d8.pdb'

and then exits.

Adding

<PropertyGroup>
    <IncludeSymbolsInSingleFile>true</IncludeSymbolsInSingleFile>
</PropertyGroup>

Could help in your situation, but I’m not sure and even if, it shouldn’t be necessary in the first place.

Sure, the since the SDK generates the deps.json file, it is possible to generate a warning if PDBs are included in deps.json files.

It is also possible to adapt the default to include the required PDBs in the single-file – but this will silently hide a likely bug in one of the dependent packages and make the app larger unnecessarily.

I filed https://github.com/dotnet/sdk/issues/3685 to track this.
