 ### Wait so what is this?
 LinqToXsd was first released back in 2009, and it was billed then as a way of '*providing .NET developers with support for typed XML programming...LINQ to XSD enhances the existing LINQ to XML technology*'.
@@ -98,5 +98,38 @@ There are some things that LinqToXsd does not support compared to `xsd.exe`:
 
 * Custom build action - the Visual Studio targets project (which allowed feeding an XSD and configuration file as a custom build action) has not been ported and there are no plans to do so at the moment. This was decided because the code generation utility can be installed as a global tool using `dotnet`. Regenerating code on build can be automated by adding a Visual Studio pre-build event ([see instructions here](https://github.com/mamift/LinqToXsdCore/blob/master/LinqToXsd/README.md#regenerating-code)). 
 
+## Best practices
+
+### 1. Include the generated source code in git or source control!
+
+NOTE: Ignoring *.xsd.cs files is a default when you use Visual Studio's [.gitignore file](https://github.com/github/gitignore/blob/main/VisualStudio.gitignore) - please remove the *.xsd.cs line from your gitignore file if this is present.
+
+It's come to my attention that some users are **ignoring the generated code** output by LinqToXsdCore in git or their chosen source control system. It seems to be a common setup to generate the code when needed, but ignore it's output in git, despite the code being compiled into DLLs and assemblies that make up part of the app.
+
+**PLEASE DO NOT DO THIS.** Do not assume the code output of LinqToXsdCore is perfect or beyond fault. It is ultimately a program written by humans and thus not without flaws.
+
+Any code that makes it to production, whether it's generated by a program or written by a human or AI, SHOULD BE TRACKED IN SOURCE CONTROL. Besides the obvious reasons (like production system code not being managed by source control), the code generated by LinqToXsdCore is NOT PERFECT. Like any program, it has bugs, and those bugs can sometimes manifest as subtle code generation mistakes.
+
+IF YOU ARE IGNORING THE CODE, THERE'S NO WAY TO COMPARE AND CONTRAST CHANGES FROM VERSION TO VERSION AND THIS MAKES TROUBLESHOOTING THE ORIGIN OF THE BUG **MUCH HARDER**.
+
+This applies to **any** code generation tool, like [nswag](https://github.com/RicoSuter/NSwag) or [WCF's svcutil.exe](https://learn.microsoft.com/en-us/dotnet/framework/wcf/feature-details/understanding-generated-client-code); YOU SHOULD ALWAYS TRACK CODE THAT ENDS UP IN A PRODUCTION SYSTEM. 
+
+Consider this scenario: 
+- You use LinqToXsdCore to generate code that is deployed in AppA v1, and you ignore the generated code in git.
+- Later on you push an update to AppA, v1.5 and in so doing, you update the LinqToXsdCore version as well.
+  - This newer version of LinqToXsdCore changes generated code slightly, but doesn't break the build process.
+- Due to changes in LinqToXsdCore, runtime behavior of your app has changed. You can see the *current* version of code being generated, but because you weren't tracking any generated code in git, you have no visibility of changes that might've occurred from the previous version; *there's no delta or changeset to compare from v1 to v1.5 in git.*
+  - While you did read the release notes, it doesn't occur to you that the changes in this newer version actually affected you, as you didn't realise you were indirectly using this particular API (it's nested several level deeps in method calls), so you miss this behavior change.
+- You only notice when some awful bug occurs in production, you spend a few days troubleshooting the issue, and it only occurs to you after many hours that maybe the issue was a dependency, and not code personally written by you or your team.
+- You take a couple stabs in the dark, and when you finally realise as part of your changes to v1.5, you updated LinqToXsdCore. You rollback LinqToXsdCore, re-run the code gen steps and see the code has changed slightly - you run another build and deploy again to staging environment, reproduce the bug and then suddenly everything is working now! Only after all this effort have you finally fixed it!
+
+The above isn't a hypothetical, it's a real world scenario related to me by a colleague who had used LinqToXsdCore in their projects. A very similar incident happened to me, except I was using nswag for OpenAPI code generation.
+
+During troubleshooting, a lot of time can be saved when you **track all production code**. 
+
+Also consider this: a lot of code is now generated by AI - would you ignore the same code in git? AI is trained on human-generated code, so AI code would be prone to contain bugs as well, so of course you track AI code. Yet for some reason, the attitude is very different when code is generated by a source-generator or other non-AI program, despite the obvious fact that those programs themselves are built and maintained by other humans, and so would contain bugs.
+
+Yes, the output of code gen tools like LinqToXsdCore can be big and verbose, but the tradeoff to tracking them, is gaining greater visibility and the ability to troubleshoot & diagnose bugs quickly. Just follow this one principle and remember it like it is an axiom: **IF IT MAKES IT TO PRODUCTION, IT NEEDS TO BE TRACKED.**

Affected code generation for XQueryX.xsd.
+    * Also fixed another code gen bug: when referencing an enum for the internal static field holding a default value, the member reference code was uncompilable when the default value in the XSD started with a number.

-	* Backported .NET 6 `DateOnly` and `TimeOnly` type serialisation for `xs:date` and `xs:time` types to .NET Standard 2.0 using [Portable.System.DateTimeOnly](https://www.nuget.org/packages/Portable.System.DateTimeOnly); there remains a .NET 6 version and a .NET Standard 2.0 version of the XObjectsCore and LinqToXsd nuget packages, but are now functionally the same.

 ## Version 3.4.1
 Nuget packages:
 * https://www.nuget.org/packages/LinqToXsdCore/3.4.1
-	* Fixes a null-reference error in the XListVisualizable which can cause debugger enumeration to fail in Visual Studio on an `XTypedElement` list.
-	* The LinqToXsd code generator tool will now filter out XSDs that target v1.1 of XML Schema as .NET only supports v1.0.
-	* Fixes a code generation bug that can be thrown in rare cases when the `xs:NCName` type is used in a schema.
-	* The code generator will now generate a `value?.ToString()` expression on a property value setter when the property type is nullable.

 ## Version 3.4.0
 Nuget packages:
 * https://www.nuget.org/packages/LinqToXsdCore/3.4.0
-	* `<SplitCodeFiles By="Namespace" />` now works, but it requires a new `File` filename attribute on every `<Namespace />`. **If you had set this unimplemented option in your config before upgrading, you will get an error and need to modify your config!**
-	* `<NullableReferences>` option should now be set inside `<CodeGeneration>`. It still works in `<Configuration>` for backward compatibility.
-	* New options `<UseDateOnly>` and `<UseTimeOnly>` inside `<CodeGeneration>`. When `true`, .net 6 `DateOnly` and `TimeOnly` types will be generated for `xs:date` and `xs:time` properties.
-	* _Minor breaking change:_ if you used `XObjectsCodeGen` directly (as a library), a few public APIs have changed to support splitting files by namespace. There is no breaking change for users of LinqToXsd tool and `XObjectsCore` runtime.

 ## Version 3.3.2
 Nuget packages:
 * https://www.nuget.org/packages/LinqToXsdCore/3.3.2
-	* This update only applies to the LinqToXsd global `dotnet` tool; it fixes a bug whereby a class constructor was being generated for classes for XSD elements, whose schema types are simple types, and said simple types are defined as enum restrictions on string types (like `NMToken` or `xs:string`) and the class constructor accepted a value for the enum type. The functional constructor now converts from the given string value to the inner enum type by parsing the string value and convert it to it's proper inner enum type (stored in the TypedValue property).

-	* Imported code changesets for v2.0.2 from the legacy [LinqToXsd project](https://archive.codeplex.com/?p=linqtoxsd), which generates the proper type definitions for union types.
-	* Switched to a tripartite versioning scheme.
-	* The global tool LinqToXsd now targets .NET Core 3.1 in addition to .NET Core 2.1. This allows users using either version of .NET Core to still use the global tool to generate code.

-	* Reverts "Avoid type name conflicts in generated code" from previous release, as it broke the code generation of the `BuildWrapperDictionary()` method generated inside the `LinqToXsdTypeManager`; it adds `typeof(void)` expressions, which breaks untyped `XElement` type conversion. Previous (and correct) behavior was to add `typeof(T)` expressions where T was the generated complex or global element type.
-	* Fixes an issue whereby setting a string value to an attribute whose type was `AnyAtomicType` resulted in an error.
-	* Fixes an issue when using the static Parse() or Load() methods on an internal generated type.
