Marc Gravells answer was right for me but my xsd was with extension of .xml. When I used xsd program it gave :
- The table (Amt) cannot be the child table to itself in nested relations.

As per this KB325695 I renamed extension from .xml to .xsd and it worked fine.

If you want to generate the class with auto properties  convert the XSD to XML using this then convert the XML to JSON using this and copy to clipboard the result  Then in VS  inside the file where your class will be created  go to Edit gt Paste Special gt Paste JSON as classes

simple enough  just run  at the vs command prompt   xsd your xsd  classes    which will create your cs   Note  however  that most of the intrinsic options here haven t changed much since 2 0  For the options  use xsd    or see MSDN  for example  enableDataBinding can be useful

xsd exe does not work well when you have circular references  ie a type can own an element of its own type directly or indirectly    When circular references exist  I use Xsd2Code   Xsd2Code handles circular references well and works within the VS IDE  which is a big plus   It also has a lot of features you can use like generating the serialization deserialization code   Make sure you turn on the GenerateXMLAttributes if you are generating serialization though  otherwise you ll get exceptions for ordering if not defined on all elements    Neither works well with the choice feature  you ll end up with lists collections of object instead of the type you want   I d recommend avoiding choice in your xsd if possible as this does not serialize deserialize well into a strongly typed class   If you don t care about this  though  then it s not a problem   The any feature in xsd2code deserializes as System Xml XmlElement which I find really convenient but may be an issue if you want strong typed objects   I often use any when allowing custom config data  so an XmlElement is convenient to pass to another XML deserializer that is custom defined elsewhere

xsd exe as mentioned by Marc Gravell  The fastest way to get up and running IMO   Or if you need more flexibility options    xsd2code VS add-in  Codeplex

I show you here the easiest way using Vs2017 and Vs2019 Open your xsd with Visual Studio and generate a sample xml file as in the url suggested    Once you opened your xsd in design view as below  click on xml schema explorer    2   Within    XML Schema Explorer    scroll all the way down to find the root data node  Right click on root data node and it will show    Generate Sample XML     If it does not show  it means you are not on the data element node but you are on any of the data definition node      Copy your generated Xml into the clipboard Create a new empty class in your solution and delete the class definition  Only Namespace should remain While your mouse pointer focused inside your class  choose  EDIT-  Paste Special-  Paste Xml as Classes

I used xsd exe in the Windows command prompt   However  since my xml referenced several online xml s  in my case http   www w3 org 1999 xlink xsd which references http   www w3 org 2001 xml xsd  I had to also download those schematics  put them in the same directory as my xsd  and then list those files in the command       C  Program Files  x86  Microsoft SDKs Windows v8 1A bin NETFX 4 5 1 Tools xsd exe   classes  language CS your xsd xlink xsd xml xsd
