Build automation - Deployment Center - failing System.Text.Json 8.0.0.4 - Including fix C# ASP.NET

Question

I have getting an error with my latest build using DotNet 8.0 when using the "Deployment Center" on Azure which is connected to my git repo. I couldn't find a fix specifically online so I dug deeper and through trail and error I've come to this solution.

..... Could not load file or assembly 'System.Text.Json, Version=8.0.0.4,	

Regardless of SDK version you have selected as preffered, it seems to auto want to go for sdk version 9 of DotNet wich may not be desired.

I have come up with a simple workaround:

1. Check out your versions of the DotNet in your application using console.
   
2. Create a global.json file with the following code:

      {  
       "sdk": {
          "version": "8.0.400" // Put your version here   
      	}
      }
   

3. Commit and push the changes for the Deployment Center to run the auto build and now it should build :)

Answer 1

System.Text.Json 8.0.0.4 has a security vulnerability and should not be used. 9 is the current version for all frameworks. You should update your nuget package references in the application project.
