Sdk: Be able to set an icon to standalone applications

[Yves57]

When building a standalone application, it would be nice to be able to set an icon (the Roslyn /win32iconoption in fact).

@schellap @gkhanna79 @blackdwarf this would have to be added to dotnet.exe after renaming. Thoughts?

[schellap]

It sounds like we are going to need two exes

1. The muxer exe that carries dotnet branding.
2. The corehost exe that carries no branding and CLI would post process this for the developer.

For 2, potentially CLI can ask roslyn package expose this capability or CLI carries or depends on rc.exe to bake this into the published corehost exe.

I am not sure if we can overwrite the dotnet branding using mt.exe. If we can then we dont need 2 exes.

If this feature will not be in the RTM, is there a post build workaround that can be used to inject an icon into the executable?

Anything that can be done here?

Bump, it'd be really nice if there was an option to do this without resorting to hacks and adding resources in post-compilation steps.

Are there any intentions to fix this (and related issues) within the next couple of years or it'd be smarter to just find lasting workarounds?

We are looking into this for applications targeting windows in the 3.0 time frame. I have updated the milestone for this issue.

There is a corresponding issue here https://github.com/dotnet/core-setup/issues/4193. The work is underway - right now it is scoped to windows only (both from where it is built and what is being built).

This is being fixed here: https://github.com/dotnet/sdk/pull/2545.
