It seems the constructed path is malformed and we are attempting to validate and build any existing plugins which is leading to a crash.

🎯 Issue Triage

The C# generator (@azure-typespec/http-client-csharp-mgmt) crashes on Windows when the path to the plugin directory in node_modules exceeds the Windows path length limit. The \\?\ long-path prefix is applied but fails because the path contains a forward slash from the scoped npm package name (@azure-typespec/http-client-csharp-mgmt), which is invalid with that prefix.

🔍 Analysis

Key error:

The filename, directory name, or volume label syntax is incorrect. :
'\\?\C:\Users\...\TempTypeSpecFiles\node_modules\`@azure-typespec/http-client-csharp-mgmt`'

Affected stack:

• Microsoft.TypeSpec.Generator.GeneratorHandler.FindPluginProject(String directory)
• GeneratorHandler.BuildPluginIfNeeded
• GeneratorHandler.AddPluginDlls
• GeneratorHandler.LoadGenerator

Root cause: Windows \\?\ extended-length path prefix (used to bypass the 260-character MAX_PATH limit) requires all path separators to be backslashes. The npm scoped package name @azure-typespec/http-client-csharp-mgmt contains a forward slash /, which is illegal in the \\?\ format, causing a "filename or volume label syntax is incorrect" error.

Affected components:

• Microsoft.TypeSpec.Generator.dll — GeneratorHandler.FindPluginProject
• Library: Azure.ResourceManager.ContainerOrchestratorRuntime
• Generator version: 1.0.0-alpha-20260708165337.ee0cb3f
• TypeSpec compiler: 1.13.0

Potential fix: When constructing paths for FindPluginProject (and related methods), forward slashes in npm-style package names should be normalized to backslashes before applying the \\?\ prefix.

📝 Suggested next steps

• In GeneratorHandler.FindPluginProject, normalize the directory path (replace / with \) before applying the \\?\ extended-length path prefix on Windows.
• Add a test case covering plugin discovery when the plugin is an npm scoped package installed in a deeply nested path.
• Consider whether the same path normalization is needed in other GeneratorHandler methods that receive directory paths from the emitter.
