It's just that it's the default program.cs of asp.net

It's just that it's the default program.cs of asp.net

well not really because the default program.cs don't throw that error

T

TeBeCo•3/7/25, 5:20 PM

so you changed something somewhere or added code that throw

T

TeBeCo•3/7/25, 5:20 PM

and if this line is pointed it's because it happen on startup somewhere

T

TeBeCo•3/7/25, 5:21 PM

anywhere related to startup

T

TeBeCo•3/7/25, 5:21 PM

send your repo link, not just that file

T

TeBeCo•3/7/25, 5:21 PM

because it could be in other file like launchSettings or appsettings etc ...

sln does not build with the compose proj

T

TeBeCo•3/7/25, 8:28 PM

the api on itself runs if I unless the compose proj

T

TeBeCo•3/7/25, 8:28 PM

are you using VS or rider ?

lol wat

T

TeBeCo•3/7/25, 8:30 PM

is this a windows container or a linux container ?

T

TeBeCo•3/7/25, 8:31 PM

i can't understand the app as it's not a common language we both use (ie: i don't speak italian, but i can read my lang + english)

T

TeBeCo•3/7/25, 8:31 PM

but i also have no error when I press F5

T

TeBeCo•3/7/25, 8:33 PM

also ... the compose file

context : .

context : .

context : .

context : . looks wird

T

TeBeCo•3/7/25, 8:33 PM

because it's in a subfolder and using

as if it was in sln folder

T

TeBeCo•3/7/25, 8:34 PM

T

TeBeCo•3/7/25, 8:34 PM

that's exactly what this error means

T

TeBeCo•3/7/25, 8:34 PM

look at the path

T

TeBeCo•3/7/25, 8:34 PM

to reproduce

T

TeBeCo•3/7/25, 8:34 PM

forget your IDE

T

TeBeCo•3/7/25, 8:34 PM

docker compose -f .\build\docker-compose.yml -f .\build\docker-compose.override.yml build

docker compose -f .\build\docker-compose.yml -f .\build\docker-compose.override.yml build

docker compose -f .\build\docker-compose.yml -f .\build\docker-compose.override.yml build

docker compose -f .\build\docker-compose.yml -f .\build\docker-compose.override.yml build

T

TeBeCo•3/7/25, 8:36 PM

T

TeBeCo•3/7/25, 8:36 PM

that path doesn't exists

T

TeBeCo•3/7/25, 8:36 PM

T

TeBeCo•3/7/25, 8:37 PM

that works alread better when fixing files and path

T

TeBeCo•3/7/25, 8:37 PM

your renamed your project and forgot to fix your entire docker files

T

TeBeCo•3/7/25, 8:37 PM

@WhiteCharun

T

TeBeCo•3/7/25, 8:38 PM

I'm closing this thread

T

TeBeCo•3/7/25, 8:38 PM

TLDR: when you rename your project and your folder

T

TeBeCo•3/7/25, 8:38 PM

you need to fix your path in compose file + dockerfile

T

TeBeCo•3/7/25, 8:38 PM

and your

context

context

is wrong in the compose file I think

T

TeBeCo•3/7/25, 8:38 PM

T

TeBeCo•3/7/25, 8:38 PM

this is working for me now
