How do you create C# classes from the NeTEx XSD?

Answer: It is possible to create C# classes in different ways.

There are many tools out there, but for instance, you could use the Microsoft xsd.exe tool or the mganss/XMLSchemaClassGenerator tool available on Github at https://github.com/mganss/XmlSchemaClassGenerator

Currently there are some issues if you try to use the official NeTEx XSD as a starting point with either of these tools.

However, the above mentioned tools work fine if you use them together with certain set of XSD-files available from Data4PT. The file set is designed to be compatible with the official NeTEx XSD and to cover many important use cases. It does however not cover all use cases possible with the offical schema. There is an interactive graphical presentation of the adapted and reduced XSD available at https://data4pt.org/NeTEx/GraphicKit/Documention_of_reduced_XSD.html

If you wish to try out this reduced XSD, you can download it at https://data4pt.org/NeTEx/GraphicKit/XSD_reduced.zip

The work steps if you are using the Microsoft tool are:

1. Get the zipped XSD. Extract the ZIP to a folder.
2. Make sure that you have a recent version of the xsd.exe. It is part of the .NET Framework Developer Pack and can be downloaded from https://dotnet.microsoft.com/download/dotnet-framework
3. Install the developer pack. The xsd.exe will be placed in a folder with a path similar to C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools
4. Open a command prompt in the same folder as where the NeTEx_publication_reduced-NoConstraint.xsd resides.
5. Execute the following command (you may have to adapt the path to xsd.exe): "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\xsd.exe" /c /language:C# gml_combo_v3_2_1_simplified.xsd NeTEx_publication_reduced-NoConstraint.xsd

The work steps if you are using the MGANSS tool are:

1. Get the zipped XSD. Extract the ZIP to a folder with a path such as C:\tmp\codegen_M.
2. Download the binary from https://github.com/mganss/XmlSchemaClassGenerator/releases and expand it to a separate folder.
3. Open a command prompt in the same folder as where the NeTEx_publication_reduced-NoConstraint.xsd resides.
4. Execute the following command (you may have to adapt the path to the exe): C:\tmp\codegen_M\XmlSchemaClassGenerator.Console.exe NeTEx_publication_reduced-NoConstraint.xsd -n http://www.opengis.net/gml/3.2=gml -v
