How to upgrade LDC

This version of LDC improves stability, resolves reported bugs and introduce support for LISA v2.

• Unified session handling to enable JSON also for LDC.Attribute
• Verify timestamp after generating datastructure and retry if changed.
• Added validation and re-generation of options queries, primarily to support LISA v2
• Workaround error in logging due to missing settings combined with insufficient privileges.
• Switched to VS2022 v143 C++ compiler
• Removed dependency for deprecated .Net Framework v4.0
• Handle missing transaction for batched update.
• Added handling of more problematic characters to file-level caching.
• Worked around potential race-condition for accessing session-table.
• Extended database level timeout for jobs (ie LISA) to 30 minutes (instead of 5 minutes) for LISA to better cope with slow databases in cloud.
• Detect and recover from memory fragmentation.
• Improved support for batch operations via COM interface with compatibility hack for stateless operation.
• Worked around compatibility issue with LISA and assumptions about stateful batch updates.
• Reduced risk for locking issues.
• Worked around problems with trashcan optimization for nested queries.
• Fixed problem related to mIxEd case and formatting of key names that broke generic support for loading LDC settings from environment variables.
• Refactored internal mappings to avoid unnecessary usage of database ID.
• Unified rules for filebased caching.
• Ensure that large values read from Redis are cached locally to reduce network traffic.
• Refactored session handling to avoid loading the complete session list.
• Unified default ttl.
• Unified mapping between database name and id.
• Enforce 1h default TTL for all content to avoid problems with stale caches if Redis fails.
• Improved error reporting for leaked C++ exceptions.
• Added two-way mapping between database name and id.
• General support for running LDC without any configuration.
• Activated caching for XML datastructure for LISA.
• Improved robustness for optimized trashcan queries.
• Improved robustness for async updates.
• Reset update-mode after successfull update.
• Unified batched updates.
• Ensure update-flag is only updated for actual updates.
• Switched default connection strings to use MSOLEDBSQL19, deprecated SQL Server Native Client will now require explicit connection string.
• Use direct accessor helpers.
• Added logging for session timestamps.
