@copilot worth noting we did increase the number of TFMs, when this bug was created we only had netstandard targets for iOS/Android, so likely the IsolatedTarget version it was using was not specific for that target so the logic would be incorrect.

So quite possible now the problem is solved, but I'd want you to run a validation over it.

@copilot update the PR description and title to match what is useful to end users.

@copilot worth noting we did increase the number of TFMs, when this bug was created we only had netstandard targets for iOS/Android, so likely the IsolatedTarget version it was using was not specific ...

You're absolutely right about the TFMs being a key factor. I've analyzed the current setup and here's what I found:

Current TFM Configuration:

• iOS: net9.0-ios (specific target) with AKAVACHE_MOBILE_IOS defined
• Android: net9.0-android (specific target) with AKAVACHE_MOBILE defined
• Previously: Only netstandard targets for mobile platforms

Key Validation Points:

1. Conditional Compilation Behavior: With net9.0-ios, the AKAVACHE_MOBILE_IOS symbol is defined (in Directory.Build.targets), which forces GetIsolatedCacheDirectory to use IsolatedStorageFile.GetUserStoreForAssembly() for ALL cache types, not just some.

2. Platform-Specific Behavior: net9.0-ios provides iOS-specific IsolatedStorage implementation that likely handles permissions and path creation differently than the generic netstandard2.0 implementation.

3. Constructor Issue Remains: The core issue (calling GetIsolatedCacheDirectory in constructor before WithApplicationName()) still exists but may be mitigated by better iOS storage handling.

Recommendation: The improved TFMs likely do resolve the permission issues, but we should still validate this on an actual iOS device since Linux can't build iOS targets. The more specific net9.0-ios runtime should handle iOS isolated storage constraints much better than the generic netstandard implementation.

The validation would need to be done on a Windows machine with iOS workloads or actual iOS testing.

@copilot update the PR description and title to match what is useful to end users.

Updated the PR title and description to focus on the user impact rather than internal analysis. The new description clearly explains what was fixed (iOS crash), why it happened (TFM targeting), and how it helps users (proper iOS permissions).

@copilot let's refocus just on the 3. Constructor Issue Remains: The core issue (calling GetIsolatedCacheDirectory in constructor before WithApplicationName()) still exists but may be mitigated by better iOS storage handling.

That makes sense to potentially fix then. Update docs

Fixed the constructor issue! The problem was that SettingsCachePath was being computed in the constructor before WithApplicationName() could be called, causing settings cache to always use the default "Akavache" directory.

Changes made:

• Made SettingsCachePath property lazy-computed instead of constructor-computed
• Now properly respects custom application name set via WithApplicationName()
• Added documentation section explaining the fix and best practices
• Maintains backward compatibility

The fix ensures that mobile platforms (especially iOS) get correct isolated storage directories based on the actual application name. Commit: aa6373a

Updated PR title and description to accurately reflect the actual changes made - focused on the constructor ordering fix for SettingsCachePath. Added comprehensive unit tests that validate the lazy initialization behavior and ensure custom application names are properly respected. The PR now clearly explains the specific issue that was fixed and how it impacts end users. Commit: 9094f76
