Martin Sarosi commented on AMQNET-745:
--------------------------------------
We have some recommendations for fixing common scenarios:
* To access files next to the executable, use
[AppContext.BaseDirectory|https://docs.microsoft.com/en-us/dotnet/api/system.appcontext.basedirectory#system-appcontext-basedirectory].
* To find the file name of the executable, use the first element of
[Environment.GetCommandLineArgs()|https://docs.microsoft.com/en-us/dotnet/api/system.environment.getcommandlineargs#system-environment-getcommandlineargs],
or starting with .NET 6 use the file name from
[ProcessPath|https://docs.microsoft.com/en-us/dotnet/api/system.environment.processpath#system-environment-processpath].
* To avoid shipping loose files entirely, consider using [embedded
resources|https://docs.microsoft.com/en-us/dotnet/core/extensions/create-resource-files].
These are recommendations from Microsoft
