**Related issue:** Resolves#50567
Adds JetBrains ReSharper as a Windows Fleet-maintained app (winget
`JetBrains.ReSharper`, version `2026.2.0.2`).
ReSharper is a Visual Studio extension rather than a standalone app, so
it does not follow the pattern of the other JetBrains FMAs (Rider,
PhpStorm, DataGrip, etc.), which are plain NSIS installers that take
`/S`. Reviewers should read the risks below before approving — a couple
of things can only be confirmed from a validator run.
## What's here
- `ee/maintained-apps/inputs/winget/resharper.json`
- `ee/maintained-apps/inputs/winget/scripts/resharper_install.ps1` /
`resharper_uninstall.ps1`
- Generated `ee/maintained-apps/outputs/resharper/windows.json` +
`apps.json` entry
- Icon (`Resharper.tsx`, website PNG, alphabetical `index.ts` entries),
generated from JetBrains' own brand asset
## Decisions that differ from the other JetBrains FMAs
**`use_display_version_for_patch` is omitted.** Every other JetBrains
winget input sets it, but the ReSharper manifest has no
`AppsAndFeaturesEntries`, so the ingester hard-errors with
`use_display_version_for_patch is set but no DisplayVersion found in
winget manifest`. The patch policy therefore compares against winget's
`2026.2.0.2`.
**Custom `exists_query` instead of `fuzzy_match_name`.** The prefix is
loose enough to match a possible per-VS-instance suffix, and excludes
the separate ReSharper C++ and ReSharper SDK products:
```sql
SELECT 1 FROM programs WHERE name LIKE 'JetBrains ReSharper%' AND name NOT LIKE 'JetBrains ReSharper C++%' AND name NOT LIKE 'JetBrains ReSharper SDK%' AND publisher = 'JetBrains s.r.o.';
```
**Install script detects Visual Studio.** It builds `/VsVersion` from
the instances `vswhere` reports and runs the installer with
`/Silent=True /PerMachine=True /SkipEtwService=True`:
- `/PerMachine=True` — the installer otherwise targets `%LocalAppData%`,
which under Fleet's SYSTEM context would land in the SYSTEM profile
instead of the developer's. The path is not configurable
([RSRP-428991](https://youtrack.jetbrains.com/issue/RSRP-428991)).
- `/SkipEtwService=True` — JetBrains documents that `EtwHostService.msi`
always raises a UAC prompt, so a fully silent install of every component
is not possible
([SUPPORT-A-3189](https://youtrack.jetbrains.com/articles/SUPPORT-A-3189)).
- It then waits for the uninstall registry entry (what osquery reads),
because the web bootstrapper can outlive its own exit code, and logs the
resulting ARP entries.
**Uninstall removes every matching entry**, since ReSharper registers
one per Visual Studio instance, using the defensive `UninstallString`
parser and appending `/Silent=True` rather than the NSIS `/S`.
Switches come from [JetBrains' silent install/uninstall
article](https://resharper-support.jetbrains.com/hc/en-us/articles/207241485-How-to-use-silent-install-and-silent-uninstall-of-ReSharper-via-Command-Line),
not guesswork.
## `unique_identifier` is provisional
`program_publisher` is verified — `JetBrains s.r.o.` is hard-coded next
to the ARP value names (`DisplayName`, `DisplayVersion`,
`UninstallString`, `Publisher`) in `JetBrains.Platform.Installer.exe`,
extracted from the installer.
The **DisplayName is not verifiable offline.** The winget URL is a
two-stage web bootstrapper: the 69 MB `.web.exe` contains
`JetBrains.Platform.Installer.Bootstrap.exe`, which downloads the
JetBrains dotUltimate installer, which downloads the product packages.
The ARP entry is written by that downloaded stage under
`Software\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}`, with
`DisplayName` taken from a per-VS-host `PresentableName`. So `JetBrains
ReSharper` is a best-supported guess.
It can be confirmed from a validator run:
`cmd/maintained-apps/validate/windows.go` searches `programs` with a
loose `LOWER(name) LIKE '%…%'` on both the catalog name and
`unique_identifier`, and logs `Found app: '<DisplayName>' … Version:
<ver>` after running `MutateSoftwareOnIngestion`. That reveals both the
true DisplayName and the post-mutation version. The install script
prints the same information. **Expect a follow-up commit correcting
`unique_identifier` (and possibly the exists query) once that log
lands.**
## Risks
1. **Payload is not pinned.** The SHA covers only the 69 MB
bootstrapper; roughly 1.7 GB is fetched from `download.jetbrains.com` at
install time. JetBrains publishes only a `windowsWeb` download for
ReSharper, so there is no offline installer to point at. Install
duration may exceed script timeouts.
2. **Requires Visual Studio.** With no VS present the installer has
nothing to install, so the script exits 1 with a clear message.
`windows-latest` runners ship Visual Studio 2022 Enterprise, so
validation should be able to install.
3. **`/PerMachine=True` conflicts with pre-existing per-user installs.**
JetBrains states machine-wide mode "is not compatible with existing
installations in user profiles"; one must be removed first.
4. **`/SkipEtwService=True` omits the ETW host service**, so
dotTrace/dotMemory profiling integration is incomplete. This is the
documented tradeoff for an unattended install.
5. **Version reconciliation unconfirmed.** If the DisplayName ends in a
marketing version, the JetBrains name-based version mutation fires and
the validator's prefix check passes; a VS-suffixed name would instead
fall back to the registry `DisplayVersion`.
# Checklist for submitter
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [x] Timeouts are implemented and retries are limited to avoid infinite
loops
## Testing
- [x] `go test ./ee/maintained-apps/...` passes; both output JSON files
parse; generated SHA matches the winget manifest.
- [ ] QA'd all new/changed functionality manually — **not done.**
Install/uninstall need a Windows host with Visual Studio; relying on the
FMA Windows validator, which is also how `unique_identifier` gets
confirmed.
