Hi Avinash Arora

I understand you're facing a .NET version mismatch in the Azure sandbox. Here’s how to resolve it:   

If you can't install .NET 7.0, change your project to target .NET 8.0: 

1.Access Cloud Shell: 

Open Azure Sandbox 

Launch Cloud Shell. 

2.Navigate to Your Project: 

cd ~/sas  # Adjust as needed

3.Open the .csproj File: 

code *.csproj

4.Update the <TargetFramework>: Change this line: 

<TargetFramework>net7.0</TargetFramework>

to: 

<TargetFramework>net8.0</TargetFramework>

6.Save the Changes:After making the modification, save the file by pressing Ctrl + S or using the file menu. 

 7.Rebuild and run your app: 

dotnet build
dotnet run
