.NET Framework 4.6升级至4.8：后续检查与Git提交疑问

1. Checks to Confirm Your App Runs on .NET 4.8 #

• Verify project target framework: Open your .csproj file and confirm it contains <TargetFrameworkVersion>v4.8</TargetFrameworkVersion>. For web projects, check that any <TargetFrameworkProfile> (if present) aligns with 4.8.
• Inspect web.config (web apps only):
  • Look for <httpRuntime targetFramework="4.8" /> and <compilation targetFramework="4.8" />—these directives force IIS to use the 4.8 runtime.
  • Review assembly binding redirects: Ensure redirects for system assemblies (like System.Core, System.Web) point to versions compatible with 4.8 to avoid runtime conflicts.
• Validate runtime version at execution: Add a quick debug check to output the current runtime version. For example:

  // Log or display this value in a test environment
  string runtimeVersion = System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion();
  Console.WriteLine(runtimeVersion); // Should return a string like "v4.0.30319.42000" (the 4.8 runtime build number)
  

• Confirm framework installation: Check that the machine running the app has .NET Framework 4.8 installed (via Control Panel > Programs > Programs and Features).
• Test core functionality: Run critical workflows (database operations, API integrations, UI interactions) to ensure no unexpected breaks—while 4.8 is backward-compatible, some obsolete APIs or edge-case dependencies might need adjustment.
• Audit NuGet packages: Ensure all installed packages are compatible with .NET 4.8. Update any older packages that have explicit dependencies on lower framework versions.

2. Which Files to Commit to Git #

You should commit all three files (.csproj, package.config, web.config) to Git. Here’s why:

• .csproj: This file defines the project’s target framework. Skipping it means other developers or build servers will load the project with the old 4.6 setting.
• web.config: Contains runtime settings, binding redirects, and target framework attributes required for the app to run correctly on 4.8. Omitting this could lead to runtime errors or the app defaulting to an older framework version.
• package.config: If the auto-upgrade modified this file (e.g., added compatibility packages, updated dependency versions), committing it ensures all team members use a consistent set of packages compatible with 4.8. Skipping it may cause dependency mismatches on other machines.

Only exclude files if you’re 100% certain the changes are irrelevant (like auto-generated comments), but in most cases, all three are critical for a stable, shared project setup.
