Walkthrough

The change adds WSL-aware command execution, stable and Preview v2 project templates, project migration, NuGet source resolution, deployment compatibility validation, nanoff version handling, debugger configuration updates, and related tests and documentation.

Changes

Execution and deployment

Layer / File(s) Summary
WSL execution routing
src/executor.ts, src/wsl.ts, src/prerequisites.ts
Commands now use per-operation WSL settings, Windows path conversion, WSL terminals, and execution results.
WSL build and test integration
src/dotnet.ts, src/testExecution.ts, src/nanoclrManager.ts
Build and test flows restore packages and invoke MSBuild, emulator, and bridge processes through WSL-aware execution.
Deployment compatibility validation
src/debugger/bridge/dotnet/..., src/debugger/bridge/nanoBridge.ts, src/dotnet.ts
Deployment images are parsed and checked against device native assemblies before deployment.

Project families and NuGet

Layer / File(s) Summary
Family-specific templates and project creation
src/projectTemplates.ts, src/createProject.ts, src/utils.ts, src/extension.ts, scripts/build.ps1
Project creation selects stable or Preview v2 templates and generates family-specific package and project files.
NuGet sources and project migration
src/nuget.ts, src/test/suite/extension.test.ts
NuGet operations resolve configured sources, restore packages, update references, and migrate projects with rollback on failure.

Debugger and tooling updates

Layer / File(s) Summary
Debugger defaults and configuration
README.md, docs/debugging.md, package.json, src/debugger/*
Default verbosity is now none when no explicit setting is supplied.
Debug configuration and activation
src/extension.ts, src/dotnet.ts
Debug output paths are resolved from project builds, and activation detects the installed nanoff major version.
Tooling, build setup, and documentation
package.json, scripts/build.ps1, src/multiStepInput.ts, nanoFirmwareFlasher, README.md
Build setup, VS Code requirements, flasher arguments, firmware tooling, and project documentation were updated.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 07653

The PR adds deployment compatibility checks, WSL-backed execution, and package/project updates, but the current behavior can allow crafted workspace paths to execute local shell commands, accept incomplete or unverified restored packages, and break selected WSL or Preview v2 build and deployment flows. These issues should be fixed or explicitly accepted before merging.

remove the unsupported flash and positional target tokens, use the required
named-option syntax, include the update option so firmware update dispatch
occurs, and replace the unsupported backup token with the supported backup path
or file option.

- Around line 797-816: In src/dotnet.ts lines 797-816, update the deployment
flow after checkDeploymentCompatibility returns to exit when currentDeployId !==
thisDeployId before queuing visible deployCommands. In src/dotnet.ts lines
955-1003, add the same cancellation check after validation and immediately
before each hidden command is executed, returning for stale deployments; use the
existing currentDeployId and thisDeployId symbols.
- Around line 815-817: Update the deploy command flow around
Executor.runInTerminal so each command executes synchronously, waits for its
result, and stops immediately when a command fails; do not queue the remaining
commands after the first failure, while preserving the existing command order
and success logging behavior.

Inline comments:
In `@src/dotnet.ts`:
- Around line 53-63: Update getNanoffMajorVersion to stop invoking nanoff
--version and instead query the installed global tool through a supported
command such as dotnet tool list -g. Preserve the existing cached promise, parse
the nanoff version’s major component from the command output, and return null

- Around line 84-92: Update buildNanoffFlashCommand so the legacy --backup

using the generated backup file’s directory while preserving the existing nanoff
v2 command behavior.

In `@src/executor.ts`:

preserving the known success/failure mapping for defined codes. Add a timeout

71-78: 🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Injection (CWE-78): Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Reachability: External · Exploitability: Moderate

Escape deployment argument values before building the terminal command.

serialPath, imagePath, and fileDeploymentPath are interpolated without shell escaping. A quote-bearing workspace path can inject shell syntax when TerminalShellIntegration.executeCommand executes the command. Use shell-specific escaping or a structured launcher.

163-163: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Convert deployment image paths before sending them to a WSL bridge.

When NanoBridge('deployment') uses WSL, checkDeploymentCompatibility sends Windows paths from uniqueBinFiles unchanged. DeploymentCompatibility.ReadAssemblies then calls File.ReadAllBytes inside WSL, so paths such as C:\workspace\App.bin can fail and block deployment. Map imagePaths with toWslPathArgument when this._executionKind uses WSL.

Inline comments:
In `@src/createProject.ts`:
- Line 136: Update AddTemplatePackages around the project.replace call to verify
that the NFProjectSystem.CSharp.targets import anchor exists before inserting
itemGroup; if it is absent, throw an explicit error instead of returning the
unchanged project. Preserve the existing insertion behavior when the anchor is
present.

In `@src/dotnet.ts`:
- Around line 109-110: Update the cached promise in initializeNanoffVersion so a
null detection result clears nanoffMajorVersionPromise before returning.
Preserve caching for successful version detection, allowing later deployment or
flashing attempts to retry after nanoff becomes available.
- Around line 708-718: Update the solution-handling branch of getProjectFamily
to reuse getPackagesConfigPaths(fileUri) instead of scanning only immediate
child directories. Use the resolved package configuration paths to inspect all
solution projects, including nested projects such as src/Foo/Foo.nfproj, while
preserving the existing family-detection behavior.

In `@src/executor.ts`:
- Line 198: Update the terminal-close handling in Executor so WSL terminals are
removed from Executor.terminals by terminal identity rather than the derived
cache key. Ensure onDidCloseTerminal deletes the matching closed terminal entry
for both WSL and non-WSL terminals, allowing the execution methods to create a
replacement when needed.

In `@src/extension.ts`:
- Around line 688-690: Update the promise created in the installDotNetTool flow
around Executor.runExecFile so errors thrown by the async callback, including
installDotNetTool, are caught and the outer promise is settled rather than left
pending. Preserve the existing successful execution and ensure
initializeExtensionInBackground can continue to check the nanoff version after
an update failure.

In `@src/nuget.ts`:
- Line 93: Update the response handling in the NuGet source search function so
it validates that data.data is an array before returning or iterating it. Treat
missing or invalid data as an empty result for that source, preserving
Promise.allSettled per-source isolation and preventing the loop at line 102 from
receiving undefined.
- Line 16: In src/nuget.ts lines 16-16, update the extractZip import to use
default ES module syntax instead of require-style assignment; in src/nuget.ts
lines 162-162, preserve the caught error as the cause when constructing the
replacement Error. Both sites require direct changes to satisfy the lint rules.
- Line 91: Update the NuGet search parameter in the relevant search function to
set prerelease to true, allowing preview-only packages to be returned; leave
stable-versus-preview filtering to the version picker’s existing logic.
- Around line 281-285: Update the endpoint construction in the resource-loading
flow to push a source only when it has at least one usable endpoint: a
discovered SearchQueryService or PackageBaseAddress URL. Preserve the existing
source and endpoint values for valid resources so the later no-enabled-source
guard can throw when none are usable.
- Around line 202-203: Update the restore flow around extractZip so archive
contents are extracted into a temporary directory and destination is replaced
only after extraction succeeds; alternatively, ensure extraction failure removes
destination before propagating the error. Preserve the existing successful
restore behavior and prevent partial destination contents from being treated as
restored on subsequent attempts.
- Around line 814-816: Update the libraryPath selection in addPackage to derive
the HintPath from the project family and package layout rather than treating
every 2.x version as lib\netnano1.0. Keep nanoFramework.TestFramework versions
3.0.77 and 4.0.0-preview.45 mapped to lib, while preserving the existing layout
for other packages.
- Around line 190-193: Update restorePackage and the service-index request flow
to require HTTPS for package and index URLs, including rejecting any curl
redirects that resolve to HTTP. Before extracting the downloaded archive,
validate it against a trusted package hash or signature and abort restoration
when validation fails.

In `@src/prerequisites.ts`:
- Line 51: Update prerequisites validation around commandExists to accept an
ExecutionKind and evaluate enabled WSL build and tooling workflows in their
actual execution contexts. Ensure WSL builds validate msbuild and nuget using
WSL command checks even when nanoFramework.wsl.tooling is false, rather than
deriving the context solely from shouldUseWsl or the tooling setting.

In `@src/projectTemplates.ts`:
- Line 81: Update the packageRegex used by getTemplatePackages to accept package
attributes in any order and allow additional attributes before the self-closing
terminator. Align its matching behavior with the tolerant package-element
pattern already used in nuget.ts, while continuing to capture the package id and
version values.

In `@src/testExecution.ts`:
- Line 192: Normalize the MDP task path after joining the segments in the
conditional argument construction, matching getPreviewWslMetadataTaskPath by
replacing backslashes with forward slashes before assigning
NF_MDP_MSBUILDTASK_PATH.
- Around line 98-100: Update the child process handling around
Executor.spawnProcess to add a 120000 ms timeout; when it expires, kill the
child process and resolve the build-step result as false, while preserving
normal completion behavior.
- Around line 20-24: Update nfProjectSystemPath to import and reuse
getProjectFamily from dotnet.ts instead of reading packages.config and detecting
the family locally. Build the nanoFramework path from the returned family value,
preserving the shared behavior used by buildNanoFrameworkProjectSystemPath.
