Hi MUKISA JOHNMARY,

Thank you for reaching out to Microsoft Q & A forum. 

Here the project targeting .NET 7, but you’d like to use .NET 8 instead. In this case, you have two options: 

1.Install .NET 7: If you prefer to keep the project as it is, you can install the .NET 7 SDK from the official Microsoft website: 

Download .NET 7 SDK 

2.Upgrade the project to .NET 8: If you'd rather use .NET 8, follow these steps: 

1.Update the Target Framework: 

Open the .csproj file (likely named ContosoPizza.csproj) and look for this line: 

<TargetFramework>net7.0</TargetFramework>

Change it to: 

<TargetFramework>net8.0</TargetFramework>

2.Update NuGet Packages: 

If there are any NuGet packages targeting .NET 7, you might need to update them. You can do this through the Visual Studio NuGet Package Manager or by running: 

dotnet add package <PackageName> --version <LatestCompatibleVersion>

3.Clear and Restore Dependencies: 

Run these commands to ensure everything’s fresh: 

dotnet clean
dotnet restore
 

4.Run the Project: 

Now try running the project again

dotnet watch
