DocumentFormat.OpenXml.Framework 3.2.0

Open XML SDK

[!NOTE]

v3.0.0 refactors and addresses some technical debt while retaining source compatibility as much as possible. You should be able to update your package and recompile with limited changes. However, binary compatibility was not a goal and will break that for some changes which are documented. PRs that introduced such changes are marked with a breaking-change label and were added to a list to help migrating to v3.0.0.

Please see the v3.0.0 milestone for issues and PRs that are included. For discussions, please join us at this issue.

[!IMPORTANT] The CI feed URL has changed as of 2 April, 2024. Please update to the new URL if using CI builds.

Known Issues

  • On .NET Core and .NET 5 and following, ZIP packages do not have a way to stream data. Thus, the working set can explode in certain situations. This is a known issue.
  • On .NET Framework, an IsolatedStorageException may be thrown under certain circumstances. This generally occurs when manipulating a large document in an environment with an AppDomain that does not have enough evidence. A sample with a workaround is available here.

Typed classes are still in DocumentFormat.OpenXml. This means that you may reference DocumentFormat.OpenXml and still compile the same types, but if you want a smaller package, you may rely on just the framework package. - Changed type of `OpenXmlPackage.Package` to `DocumentFormat.OpenXml.Packaging.IPackage` instead of `System.IO.Packaging.Package` with a similar API surface - `EnumValue<T>` now is used to box a struct rather than a `System.Enum`. This allows us to enable behavior on it without resorting to reflection - Methods on parts to add child parts (i.e. `AddImagePart`) are now implemented as extension methods off of a new marker interface `ISupportedRelationship<T>` - Part type info enums (i.e. `ImagePartType`) is no longer an enum, but a static class to expose well-known part types as structs. Now any method to define a new content-type/extension pair can be called with the new `PartTypeInfo` struct that will contain the necessary information. - `OpenXmlPackage.CanSave` is now an instance property (#1307) - Removed `OpenXmlSettings.RelationshipErrorHandlerFactory` and associated types and replaced with a built-in mechanism to enable this - `IdPartPair` is now a readonly struct rather than a class - Renamed `PartExtensionProvider` to `IPartExtensionFeature` and reduced its surface area to only two methods (instead of a full `Dictionary<,>`). The property to access this off of `OpenXmlPackage` has been removed, but may be accessed via `Features.Get<IPartExtensionFeature>()` if needed. - `OpenXmlPart`/`OpenXmlContainer`/`OpenXmlPackage` and derived types now have internal constructors (these had internal abstract methods so most likely weren't subclassed externally) - `OpenXmlElementList` is now a struct that implements `IEnumerable<OpenXmlElement>` and `IReadOnlyList<OpenXmlElement>` where available (#1429) - Individual implementations of `OpenXmlPartReader` are available now for each package type (i.e. `WordprocessingDocumentPartReader`, `SpreadsheetDocumentPartReader`, `PresentationDocumentPartReader`), and the previous `TypedOpenXmlPartReader` has been removed. (#1403) - Reduced unnecessary target frameworks for packages besides DocumentFormat.OpenXml.Framework (#1471) - Changed some spelling issues for property names (#1463, #1444) - `Model3D` now represents the modified xml element tag name `am3d.model3d` (Previously `am3d.model3D`) - Removed `DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.PivotCacheHasRichValuePivotCacheRichInfo` - Removed `DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.RichDataPivotCacheGuid` - Removed unused `SchemaAttrAttribute` (#1316) - Removed unused `ChildElementInfoAttribute` (#1316) - Removed `OpenXmlSimpleType.TextValue`. This property was never meant to be used externally (#1316) - Removed obsolete validation logic from v1 of the SDK (#1316) - Removed obsoleted methods from 2.x (#1316) - Removed mutable properties on OpenXmlAttribute and marked as `readonly` (#1282) - Removed `OpenXmlPackage.Close` in favor of `Dispose` (#1373) - Removed `OpenXmlPackage.SaveAs` in favor of `Clone` (#1376) ## [2.20.0] ### Added - Added DocumentFormat.OpenXml.Office.Drawing.Y2022.ImageFormula namespace - Added DocumentFormat.OpenXml.Office.Word.Y2023.WordML.Word16DU namespace ### Changed - Marked `OpenXmlSimpleType.TextValue` as obsolete. This property was never meant to be used externally (#1284) - Marked `OpenXmlPackage.Package` as obsolete. This will be an implementation detail in future versions and won't be accessible (#1306) - Marked `OpenXmlPackage.Close` as obsolete. This will be removed in a later release, use Dispose instead (#1371) - Marked `OpenXmlPackage.SaveAs` as obsolete as it will be removed in a future version (#1378) ### Fixed - Fixed incorrect file extensions for vbaProject files (#1292) - Fixed incorrect file extensions for ImagePart (#1305) - Fixed incorrect casing for customXml (#1351) - Fixed AddEmbeddedPackagePart to allow correct extensions for various content types (#1388) ## [2.19.0] - 2022-12-14 ### Added - .NET 6 target with support for trimming (#1243, #1240) - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData namespace - Added DocumentFormat.OpenXml.Office.PowerPoint.Y2019.Main.Command namespace - Added DocumentFormat.OpenXml.Office.PowerPoint.Y2022.Main.Command namespace - Added Child RichDataPivotCacheGuid to DocumentFormat.OpenXml.Office2010.Excel.PivotCacheDefinition ### Fixed - Removed reflection usage where possible (#1240) - Fixed issue where some URIs might be changed when cloning or creating copy (#1234) - Fixed issue in FlatOpc generation that would not read the full stream on .NET 6+ (#1232) - Fixed issue where restored relationships wouldn't load correctly (#1207) ## [2.18.0] 2022-09-06 ### Added - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2021.ExtLinks2021 namespace (#1196) - Added durableId attribute to DocumentFormat.OpenXml.Wordprocessing.NumberingPictureBullet (#1196) - Added few base classes for typed elements, parts, and packages (#1185) ### Changed - Adjusted LICENSE.md to conform to .NET Foundation requirements (#1194) - Miscellaneous changes for better perf for internal services ## [2.17.1] - 2022-06-28 ### Removed - Removed the preview namespace DocumentFormat.OpenXml.Office.Comments.Y2020.Reactions because this namespace will currently create invalid documents. ### Fixed - Restored the PowerPointCommentPart relationship to PresentationPart. ### Deprecated - The relationship between the PowerPointCommentPart and the PresentationPart is deprecated and will be removed in a future version. ## [2.17.0] - Unreleased ### Added - Added DocumentFormat.OpenXml.Office.Comments.Y2020.Reactions namespace (#1151) - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotVersionInfo namespace (#1151) ### Fixed - Moved PowerPointCommentPart relationship to SlidePart (#1137) ### Updated - Removed public API analyzers in favor of EnablePackageValidation (#1154) ## [2.16.0] - 2022-03-14 ### Added - Added method `OpenXmlPart.UnloadRootElement` that will unload the root element if it is loaded (#1126) ### Updated - Schema code generation was moved to the SDK project using C# code generators Thanks to the following for their contribution: @f1nzer ## [2.15.0] - 2021-12-16 ### Added - Added samples for strongly typed classes and Linq-to-XML in the `./samples` directory (#1101, #1087) - Shipping additional libraries for some additional functionality in `DocumentFormat.OpenXml.Features` and `DocumentFormat.OpenXml.Linq`.
