This PR fixes an issue where generating a Kiota API client with deeply nested paths fails with a "Could not find a part of the path" error on Windows systems due to path length limitations.
Changes
SafeReadAllLinesmethod toFileHelper.csthat handles long file paths with multiple fallback strategiesCSharpFileMerger.csto use the new robust file reading methodImplementation Details
When file paths become too long (exceeding Windows' 260 character limit), standard file operations fail with path-related exceptions. The new
SafeReadAllLinesmethod first tries the normalFile.ReadAllLinesmethod, and if that fails due to path length issues, falls back to stream-based file reading that's more resilient to long paths.The solution makes minimal changes to the codebase, targeting only the specific file reading operations that were failing during the Kiota code generation process.
Fixes #1122.
