@Nick2035 Apologies for all the delay in response and all the inconvenience caused because of the issue.
Service Fabric offers multiple ways to write and manage your services. Services can choose to use the Service Fabric APIs to take full advantage of the platform's features and application frameworks. Services can also be any compiled executable program written in any language or code running in a container hosted on a Service Fabric cluster.
ASP.NET Core is an open-source, cross-platform framework for building modern cloud-based Internet-connected applications, such as web apps, IoT apps, and mobile backends. Service Fabric integrates with ASP.NET Core so you can write both stateless and stateful ASP.NET Core applications that take advantage of Reliable Collections and Service Fabric's advanced orchestration capabilities.
You can refer to this documentation for more info.
For updating Service Fabric cluster as well as the .Net Framework and to find current version you can refer to below:
