single file publish: AppContext.BaseDirectory doesn't point to apphost directory #3704
Description
Steps to reproduce
- Create a hello world program:
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
Console.WriteLine($"Base Directory: {AppContext.BaseDirectory}");
Console.WriteLine($"Assembly Location: {typeof(Program).Assembly.Location}");
}-
Publish self contained -
dotnet publish -c Release -r win-x64 -p:PublishSingleFile=True --self-contained false(or self-contained) -
Run the resulting exe file.
Expected behavior
According to the design document, AppContext.BaseDirectory is the API that developers should use to access the path where the app host resides.
The app context base directory should therefore not be in AppData\Local\Temp\.net\.
Background: I want to use this directory to load override config files.
Actual behavior
C:\demos\testcons\bin\Release\netcoreapp3.0\win-x64\publish>testcons.exe
Hello World!
Base Directory: C:\Users\ullrimar\AppData\Local\Temp\.net\testcons\53kpwgv0.3mq\
Assembly Location: C:\Users\ullrimar\AppData\Local\Temp\.net\testcons\53kpwgv0.3mq\testcons.dll
