Error when running .net 8 application with XM Cloud in local docker containers (XM Cloud Introduction) - Error NETSDK1045

Question

I wanted to run the XM Cloud Introduction Repo in local docker containers.

Reproduction steps:

1. I cloned the main branch to my local
2. I ran the init script
3. I adjusted the .env file as I'm running on windows 10
4. I stopped IIS
5. I made sure docker is running for windows and not for Linux
6. I installed dotnet 8 to meet the head application requirements
7. I ran the up script

The following error occurs on step 15/20:

Answer 1

I first thought this might be related to an old windows version I was running on. So I updated it. But that did not help. So,inspecting the docker image using

docker image inspect mcr.microsoft.com/dotnet/framework/sdk:4.8-windowsservercore-ltsc2019

revealed that my docker image was from 2022 and not the one from 12th december 2023

Seems this package cannot handle the .net 8 but only .net 6

So I manually pulled latest

docker image pull mcr.microsoft.com/dotnet/framework/sdk:4.8-windowsservercore-ltsc2019

after inspecting that version it looked like I have the new version.

I ran the up.ps1 script again and the problem was solved.
