# #11013 Remove 43 unused DotNet alias declarations

> Removed 43 unused DotNet alias declarations from the DotNet Aliases app that had no consumers anywhere in the repository, reducing total declarations from 517 to 474.

[Pull request](https://github.com/microsoft/BCApps/pull/11013) · merged into `main` (BC30) on 2026-09-07 by darjoo · 1 file (+0 -168), 1 AL · refactor · tier official · reviewed (checked by Opus)

## What changed

- Deleted 43 unused type declarations across 6 assemblies (DocumentFormat.OpenXml, netstandard, System.Security.Cryptography.Xml, MimeKit, MailKit, System.Drawing.Common)
- All 49 assembly blocks retained and verified to be non-empty after deletion
- Changes limited to a single file (dotnet.al) with 168 deletions and 0 insertions
- No external extensions can consume these aliases because DotNet interop requires OnPrem target while partners target Cloud
- Zero-usage scan performed across all 36,684 AL files to confirm none of the 43 aliases were referenced

## AL objects touched

- `src/System Application/App/DotNet Aliases/src/dotnet.al`: modified, not in the BC30 snapshot

## Context

- Work items: AB#647963
- Labels: AL: System Application, Team: Integrations
- Systems: integration, development
- From the description: "Over time it accumulated alias declarations that nothing consumes."
