Let's break down your problem and walk through targeted solutions based on the error logs you shared. First, let's recap the errors you're encountering:

This 0x80131623 exception is a .NET runtime error, typically tied to corrupted VS configurations, conflicting extensions, or broken framework components.

Error Type 2 (DBMDL Maintenance Warning) #

devenv (8604,D,0) 201b6ea9-a2dc-4eb7-93df-3b89ae574335: Database 'C:\.....dbmdl': Background clean-up skipped pages. The database may benefit from widening the online maintenance window during off-peak hours. If this message persists, offline defragmentation may be run to remove all skipped pages from the database.

Deleting the dbmdl file is a good first step, but the issue likely stems from broader VS cache corruption rather than just that single file.

Step-by-Step Solutions #

1. Test in Safe Mode to Rule Out Extension Conflicts #

Third-party extensions are one of the most common causes of VS freezes. Launch VS in safe mode to disable all extensions:

• Open Command Prompt (run as admin if possible)
• Run the command: devenv /SafeMode
  If the freezes stop, you know an extension is the culprit. Head to Tools > Extensions and Updates and re-enable extensions one by one to identify the problematic one.

2. Reset Visual Studio Settings #

Corrupted user settings can cause unstable behavior. Reset them with:

• Run from Command Prompt: devenv /ResetSettings
  Or within VS: Go to Tools > Import and Export Settings > Reset all settings (back up your custom settings first if you want to keep them)

3. Clear All VS-Related Caches #

Beyond the dbmdl file, VS stores multiple caches that can get corrupted:

• Delete the ComponentModelCache: Navigate to %LOCALAPPDATA%\Microsoft\VisualStudio\14.0\ComponentModelCache and delete all files inside
• Remove project-specific .vs folders: These hidden folders in your project directories can accumulate corrupted data—delete them (they'll be recreated automatically when you reopen the project)
• Clean temp files: Delete all files in %USERPROFILE%\AppData\Local\Temp that start with VS or devenv

4. Repair or Reinstall Visual Studio #

If the above steps don't fix the issue, your VS installation might be corrupted:

• Open the Visual Studio Installer (find it in your Start menu)
• Select your VS 2015 instance, click Modify, then choose Repair
  If repair fails, uninstall VS completely, restart your PC, then reinstall with a fresh download of the installer.

5. Repair .NET Framework #

VS 2015 relies heavily on .NET Framework 4.6+. Use the official .NET Framework Repair Tool to fix any corrupted components:

• Run the standalone tool, follow the prompts to scan for issues, and let it repair any detected problems.

6. Optimize Memory Usage (Even if Total RAM Isn't Maxed) #

The System.OutOfMemoryException might be due to memory fragmentation or per-process limits:

• Close unnecessary background apps (like other IDEs, large design tools) to free up resources
• Disable background compilation: Go to Tools > Options > Projects and Solutions > Build and Run and uncheck On Run, when projects are out of date: Build
• Lower parallel build limits: In the same Build and Run settings, set Maximum number of parallel project builds to a lower value (e.g., 2 if you have 4 cores)
