• the -a flag will now delete existing files with the .xsd.cs extension (since v3.4.17, the default output extension is now .xsd-g.cs) when outputting code
  • fixed a bug with getting the actual XML Schema version, the xs:schema\@version attribute is a user defined attribute for the schema version, it does not specify which W3C XSD specification version to validate against (i.e. v1.0 or v1.1). This has inadvertently caused linqtoxsd to skip schemas that had xs:schema\@version values that were v1.1 or higher.
  • the behaviour of the -a argument when invoking the linqtoxsd gen CLI tool is now always applied i.e. it now always searches for a .xsd.config file regardless. However, in previous versions, if a config file was not found, linqtoxsd gen would skip that XSD file - now linqtoxsd gen will simply apply default config values for those XSD files and proceed to generate code. This fixes LinqToXsd global tool bug when -a encounters an XSD with no config #8.
• added a new CLI verb sum that will emit a markdown file that summarises the generated code.
• codegen: global:: is now prefixed to the generated method GetRootType() when global:: is used in other places for namespaces with Xml in them.
• Fix duplicated shared-schema types across multiple XSDs (fixes Double includes are not ignored. #14) - when several entry-point schemas xs:import/xs:include the same shared schemas, the shared schemas' types were regenerated into every importing file, producing duplicate (and for non-partial types, uncompilable) C#.
• Removed all uses of Assert.Warn with Assert.Fail - fixed and updated some silently ignored tests as a result.
• Nuget dependency updates:
  • Portable.System.DateTimeOnly consolidated to v9.0.2.
  • Microsoft.CodeAnalysis.CSharp and Microsoft.CodeAnalysis.CSharp.Workspaces. to 5.9.0.
  • A bunch of test-only dependencies updated

v3.5.0

🔵 Needs a closer look

It spans core code-generation changes, a partial version-detection fix that may still drop user schemas with version="1.1", and broad framework/dependency upgrades that need human validation.

What changed in this PR

This PR cuts the v3.5.0 release of the LinqToXsdCore CLI, bundling several bug fixes, a new sum verb, and a large dependency/target-framework bump (net8.0 → net10.0, NUnit 5, MSTest 4.5.1, etc.). The most substantive logic changes fix duplicated shared-schema type generation across multiple XSDs (issue #14), correct XSD version detection so user-defined xs:schema@version values no longer cause schemas to be skipped, make the -a flag resilient when no .xsd.config exists (issue #8), and prefix global:: more consistently in generated using directives. Tests were hardened (replacing silently-passing Assert.Warn with Assert.Fail) and made cross-platform.

Changes:

• Code-generation fixes: merge-then-split shared schemas to avoid duplicate types, corrected GetXmlSchemaVersion, global::-qualified using directives, legacy .xsd.cs cleanup under -a.
• New sum CLI verb plus a CodeSummariser, and default-config fallback for gen.
• Wide NuGet/target-framework upgrades and cross-platform test corrections.

File	Description
XObjectsCore/​Extensions/​GeneralExtensionMethods.cs	Rewrites XSD version detection; introduces namespace/version constants (flagged: mutable statics + version="1.1" fallback).

XObjectsCode/​Src/​EnumFacet.cs /​ CompiledFacets.cs	Defers enum facet creation so member names are uniquified across the whole enumeration.
XObjectsTests/​XObjectsTests.csproj	Bumps target frameworks and test/package dependencies.
XObjectsTests/​TestExtensionsMethods.cs	Adds diagnostics helper and normalises mock-FS path separators for Unix.
XObjectsTests/​GraphTests.cs	Adds graph build/entry-point tests over generated schema libraries.
XObjectsTests/​GlobalPrefixUsingDirectivesTests.cs	New tests for global:: using-directive qualification.
