TLDR: selecting a profile with dotnet gives no errors, but just exits. Running it without a profile the app launches correctly, but does not listen on the ports I want.
I want to launch an existing asp.net site on Linux that always just worked on ms win.
When I launch the asp.net app with dotnet run, it will complain it cannot find Default profile, and it will launch the app sucessfully on ports 5000 and 5001.
When I lauch the app with dotnet run --launch-profile DevKestrel -v n it shows no failures and it builds successfully. It ends with this:
Using launch settings from /some/Some.Web/Properties/launchSettings.json...
and then it just exits there instead of keeping active and listing on ports 44328 and 44327.
In a fresh skeleton project made with dotnet new mvc -f netcoreapp3.1 the DevKestrel profile just works.
Besides some warnings like this, everything builds:
"Some.Web.csproj" (default target) (1:7) ->
(ProcessFrameworkReferences target) ->
/usr/share/dotnet/sdk/3.1.120/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(39,5): warning NETSDK1086: A FrameworkReference for 'Microsoft.AspNetCore.App' was included in the project.
