Hi Rohant Agrawal,

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>

5.Check Other Configuration Files (e.g., gateway.json): You might also need to update the .NET version in other configuration files such as gateway.json. To do this, open the file and ensure the version is updated to .NET 8.0 where required.

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
