Issue Overview: Missing Entry Point in SQLite.Interop.dll The core issue revolves around a System.EntryPointNotFoundException error, specifically indicating that the entry point SI9dbf9d88aa001ea6 cannot be found in the SQLite.Interop.dll. This error occurs during the initialization of the SQLite connection, specifically when the System.Data.SQLite.SQLite3.StaticIsInitialized() method is invoked. The error message suggests that the SQLite native interop layer…

Issue Overview: Out-of-Source Build Failures Due to Missing $(TOP) Prefix in Makefile.msc When attempting to build SQLite out-of-source on a Windows system using the provided Makefile.msc, the build process fails due to missing $(TOP) prefixes in the makefile. The $(TOP) variable is intended to reference the root directory of the SQLite source code, ensuring that…

Understanding SQLite Autoindex Corruption and Invalid Rootpage Errors Rootpage Corruption in Implicit Indexes: Schema Validation Failures The error message "malformed database schema (sqlite_autoindex_config_1) invalid rootpage" indicates that SQLite encountered a structural inconsistency in the database schema while attempting to validate an implicitly generated index. This error is triggered during schema parsing, specifically when SQLite verifies…

Understanding the SQLite Session Extension and WASM Integration The SQLite Session Extension is a powerful feature that allows tracking changes to a database, enabling functionalities like conflict resolution and synchronization.
