using: Azure app services
Stack: Asp.Net 6 API, C#
I sometimes do deployments changing a variable or even as small as changing a condition to look for something. which result in 500.30 errors from azure. When that happened recently i went into the dev console and ran the .exe file from the .Net app and i saw error there systemFileIOException: Could not load file or assembly 'Microsoft.Extensions.Primitives 8.0.0.0 (along those lines), i had this once and adding like below in the csproj file worked but now it happened again, and al already have that line in so im not sure what this means?
<PackageReference Include="Microsoft.Extensions.Primitives" Version="8.0.0" />

Your code does not seem to have loaded correctly, please add it again. What program are you creating?

2024-07-04T13:09:02.3966667+00:00 Sorry about that, but this website is totally broken i tried savig edits multiple times.... so maybe as a comment it will work.
Im using Azure App Services to deploy a >net 6 API, C#.
the problem is occasionaly when the app service restarts after new deployment i get a 500.30 (failed to start) with the reason mentioned above,
here's the line of code that i added the first time around that fixed the issue.
<PackageReference Include="Microsoft.Extensions.Primitives" Version="8.0.0" />
