 You can use C#, F# and VB to write .NET Framework apps. C# is simple, powerful, type-safe, and object-oriented while retaining the expressiveness and elegance of C-style languages. F# is a multi-paradigm programming language, enabling both functional and object-oriented patterns and practices. VB is a rapid development programming language with the deepest integration between the language and Visual Studio, providing the fastest path to a working app.

 ### Build a Container with IIS-hosted WCF Service
-Project `WcfServiceWebApp` is created from 'WCF Service Application' template in Visual Studio. A [Dockerfile](/Dockerfile.web) is added to the project. We use a [WCF image](https://hub.docker.com/_/microsoft-dotnet-framework-wcf/) as the base image, which has both HTTP and NET.TCP protocols enabled in IIS and exposes ports 80 (for HTTP) and 808 (for NET.TCP) for the container. We use the WCF image with tag `4.7.2` for .NET Framework 4.7.2 in this example, but you can change it to use other tags (eg. `4.7`) for WCF images with different versions of .NET Framework. The complete list of supported WCF tags can be found on [Docker Hub](https://hub.docker.com/_/microsoft-dotnet-framework-wcf/).
