dotnet publish won't publish self contained exe without a RuntimeIdentifier. I am passing -r in the command.

[ajmcateer]

Steps to reproduce

Run the following command
dotnet publish --self-contained true -f netcoreapp3.0 -r linux-x64

Expected behavior

Should publish a single executable file for the given runtime

Actual behavior

C:\Program Files\dotnet\sdk\3.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.RuntimeIdentifierInference.targets(127,5): error NETSDK1031: It is not supported to build or publish a self-contained application without specifying a RuntimeIdentifier. Please either specify a RuntimeIdentifier or set SelfContained to false. [C:\Users\ardsafa\Documents\git\fdere\fdere\fdere\fdere.csproj]

Alright so just figured something out. My project setup is
Command line app using .netcore 3.0
GUI app using .netcore 3.0 and Avalonia

The Gui app references the command line app to call some code directly I guess it is not passing -r to the command line app. If I manually change the csproj files for both and specify the same runtime it works. But I want to build this for all Windows, Linux, Mac its kind of a pain, to edit both each time.

[neobenedict]

Same issue.

Edit: Can be fixed by going to the linked projects .csproj file and adding a RuntimeIdentifiers tag with all the platforms you are releasing for:

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RuntimeIdentifiers>win10-x64;linux-x64</RuntimeIdentifiers>
  </PropertyGroup>

To be honest, I'm not sure if this even is a bug, but it's a useless error message that doesn't help me resolve the problem, and probably won't help others aside from finding this git issue.

There are two ways to work around this:

1. --self-contained true is actually the default when passing -r RID - there's no need to explicitly specify it and your dependencies should build fine. If set to false (platform specific, non-self-contained), that should also work.

2. Adjust your ProjectReference to the referenced app to block the global property passed via the CLI to the referenced project:

<ItemGroup>
  <ProjectReference Include="..\TestCons\TestCons.csproj" GlobalPropertiesToRemove="SelfContained" />
</ItemGroup>

The Gui app references the command line app

I think you ran into this issue: #10902 which is still open at the time of writing.

In my case I could implement a workaround as @neobenedict suggested which really not ideal.

[gandhis1]

This error is kind of silly. If you just drop the --self-contained then it works. I can't see a rational reason why having it - although it is redundant - should cause this to fail.

[bricelam]

Interestingly, passing --use-current-runtime instead of --runtime works without error. (Obviously, this isn't a valid workaround if you're targeting a different runtime.)

[bricelam]

In addition to @dasMulli's workaround, I also needed to add /p:ValidateExecutableReferencesMatchSelfContained=false

[waltdestler]

Dropping the --self-contained argument is now a less-desirable option in .NET 6, because it now gives a warning:

warning NETSDK1179: One of '--self-contained' or '--no-self-contained' options are required when '--runtime' is used.
