## What Was Fixed

### ✅ Errors Fixed (22 total resolved)

1. **Missing `using System.IO;`** (4 files)
   - Added to: Program.cs, ApiClient.cs, CommandExecutor.cs, SystemInfoMonitor.cs
   - Fixes: Path, Directory, File not found errors

2. **Environment.SpecialFolder.ProgramData** (3 files)
   - Replaced with: Environment.SpecialFolder.CommonApplicationData
   - Files: ConfigReader.cs, ServiceInstaller.cs, CommandExecutor.cs, Program.cs
   - Reason: ProgramData doesn't exist in .NET, CommonApplicationData is the standard replacement

3. **Multiple Entry Points** 
   - Removed: Main method from ServiceInstaller.cs
   - Result: Only Program.cs now has entry point
   - Note: ServiceInstaller methods now public static for utility use

4. **System.Management Missing**
   - Added: `<PackageReference Include="System.Management" Version="7.0.0" />` to csproj
   - Fixes: WMI calls in SystemInfoMonitor.cs

5. **SendActivityAsync Method Missing**
   - Added: Public async method to ApiClient.cs
   - Signature: `public async Task<bool> SendActivityAsync(object activity)`
   - Wraps SendAsync with activity endpoint

6. **DisplayName Property Issue**
   - Removed: Direct DisplayName assignment from ServiceWrapper constructor
   - Reason: DisplayName is set via ServiceInstaller in .NET, not in ServiceBase
   - Impact: DisplayName now set through SC.exe command during installation

7. **Unassigned Variable**
   - File: CommandExecutor.cs, line 25
   - Fixed: Changed pattern matching to explicit cast for `commands` variable
   - From: `if (result != null && result is Newtonsoft.Json.Linq.JArray commands)`
   - To: `var commands = result as Newtonsoft.Json.Linq.JArray; if (commands != null)`

### Warnings (Non-Critical)
- 44 nullable reference warnings (CS8618, CS8603)
- 1 async without await warning (CS1998) 
- These can be addressed later with nullable annotations

## Next Steps

1. **Install Service:**
   ```batch
   cd e:\xampp\htdocs\tracker\agent-csharp
   .\INSTALL_SIMPLE.bat
   ```

2. **Start Service:**
   ```powershell

   ```

3. **Verify Installation:**
   ```powershell
   Get-Service PCMonitorAgent
   ```

4. **Check Logs:**
   ```
   C:\ProgramData\PCMonitor\Logs\Agent_*.log
   ```
