I am trying to upgrade my project to .Net 8.0 and I have checked that the required SDK is installed on my machine by the command dotnet –list-sdks.

I also can build solution locally after upgrading my project to .Net 8.0. Now when I am doing Octopus Deploy, the deployment is failing and the error says below–

/root/.dotnet/sdk/3.1.426/Microsoft.Common.CurrentVersion.targets(1177,5): error MSB3971: The reference assemblies for “.NETFramework,Version=v8.0” were not found. You might be using an older .NET SDK to target .NET 5.0 or higher. Update Visual Studio and/or your .NET SDK.

I am not sure where else I need to upgrade the framework version or it’s related assemblies.
