Where is My Environment Variables? Journey to Linux Service

Ok, I had a .NET Core Web App running in Ubuntu behind Nginx. Everything else is fine except I can't retrieve the value of the environment variables that I put in /etc/environment.

After hours of googling, turns out systemd service strips all out except some variables. Two ways to fix this:

1. Put the environment variable in the .service config file

[Service]
Environment=MY_ENV_VAR=thevalue

2. Include /etc/environment in the service. (I don't think this is a good idea, especially for my use case).

[Service]
EnvironmentFile=/etc/environment

Sentinel One Strikes Again. No internet connection. Uninstall Sentinel One Agent.

This happened to a co-worker of mine a while back when his test application file was marked as suspicious by Sentinel One antivirus and had his internet on his laptop disabled. Today, it happened to me without any suspicious file. Probably suspicious activity, who knows. On Microsoft Edge, it says "Hmmm... your Internet access is blocked.", "Firewall or antivirus software may have blocked the connection", and "ERR_NETWORK_ACCESS_DENIED". So, I worked with my IT to uninstall the agent, but uninstalling is not without a fight. Here are the steps that I took: Since it is a Windows 11 machine with Bitlocker, I have to first get the Bitlocker key. From command prompt run: manage-bde -protectors -get C: After I verified it is the same key that the IT has, I saved the key outside of the machine. Then go to system configuration by searching for "sysconfig" or run msconfig. Under "boot" tab, check the "Safe boot" option, then click ...

Error When Generating OpenAPI Documents: Missing required option '--project'

After I installed Microsoft.Extensions.ApiDescription.Server package, I encountered the following error message when I attempted to generate OpenAPI documents at build-time on .NET 9. Missing required option '--project' The command "dotnet "..."" exited with code 1 Apparently, it was due to end slash on my attempt to change the output directory. On my csproj file, I have the following entry: <PropertyGroup> <OpenApiDocumentsDirectory>../directory/</OpenApiDocumentsDirectory> </PropertyGroup> It works correctly after I removed the end slash: <PropertyGroup> <OpenApiDocumentsDirectory>../directory</OpenApiDocumentsDirectory> </PropertyGroup>

Swagger .NET 8 Error

Swashbuckle CLI was able to output schema of my API before, but this time, it throws this error message: System.InvalidOperationException: A type named 'StartupProduction' or 'Startup' could not be found in assembly I used top level statement with minimal API on .NET 8 and nothing is changed on that, so I was not able to find anything to do with Startup type. After I investigate further by commenting line by line, I found out that the issue is on my switch statement. So it looks like the following: return config.Section?.Key switch { Value1 => services.AddSingleton<Handler1>(), Value2 => services.AddSingleton<Handler2>(), _ => throw new InvalidOperationException(); } Problem is the Section is pulled from appsettings.json and when the CLI runs, it doesn't have value, so it never returned the services object. Changing the above to the following fixed the issue: return config.Section == null ? services : config.Section.Key switch { Value1 =...
