如何正确升级ASP.NET Boilerplate？从2.3.0到3.0.0的分步指南

Hey there! Upgrading from ASP.NET Boilerplate (ABP) 2.3.0 to 3.0.0 is totally manageable, but you’ll need to tackle some key breaking changes along the way. Let’s walk through this step by step to ensure a smooth transition:

• First things first: back up your entire codebase and database. If anything goes sideways, you’ll be glad you have a fallback.
• Commit all your local changes to your version control system (Git/SVN) so your workspace is clean—no half-finished code complicating the upgrade.
• Review the official ABP 3.0.0 release notes (focus on breaking changes) to get ahead of potential code conflicts or API shifts.

• Open your solution, right-click it, and select Manage NuGet Packages for Solution.
• Switch to the Updates tab, filter for packages starting with Abp, and select all to upgrade to version 3.0.0. Critical note: keep all ABP packages on the same version—mixed versions will cause runtime errors.
• If you have custom class libraries that reference ABP packages, repeat the upgrade process for those projects too.
• After upgrading, run Clean Solution followed by Rebuild Solution in Visual Studio. Jot down any compilation errors—we’ll fix those next.

ABP 3.0.0 introduced several impactful changes; here are the most common ones you’ll encounter:

• Dependency Injection Overhaul: The old IDependencyResolver methods are deprecated. Replace direct calls to DependencyResolver.Instance with constructor injection of IServiceProvider, or use IocManager.Instance.Resolve (constructor injection is always preferred for maintainability).
• Module Initialization Adjustments: The module loading sequence was optimized. Double-check your custom modules’ DependsOn attributes to ensure correct dependencies, and update any PreInitialize/Initialize/PostInitialize logic that relies on outdated module lifecycle APIs.
• AutoMapper Version Jump: ABP 3.0.0 upgraded AutoMapper, so old Mapper.CreateMap<Source, Destination>() calls won’t work. Instead, configure mappings using IMapperConfigurationExpression via the AbpAutoMapperModule’s configuration methods.
• Permission System Updates: Permission definition logic changed. If you have a custom PermissionDefinitionProvider, adjust it to match the new 3.0.0 schema for registering permissions.
• Unified Logging: Direct calls to third-party logging libraries should be replaced with ABP’s ILogger interface to ensure compatibility with the updated logging system.

ABP 3.0.0 modifies some system tables—here’s how to update your database:

• For Entity Framework Core: Open the Package Manager Console, set your DbContext project as the default, run Add-Migration AbpUpgradeTo3.0.0 to generate a migration script. Review the script carefully to avoid accidental data loss (e.g., don’t let it drop critical fields). Then run Update-Database to apply the changes.
• For NHibernate: Generate a schema update script manually or use NHibernate’s SchemaUpdate tool to sync your database with the updated entity models.

• Start the application and check for runtime errors on launch.
• Test core workflows: user login, permission checks, business logic flows, API endpoints—make sure every existing feature works as expected.
• Pay extra attention to modules you modified during the upgrade (DI, permissions, logging) to catch edge cases.
• Check your application logs for warnings or errors that didn’t surface during testing.

• Remove any deprecated API calls or unused references cluttering your codebase.
• Update your project documentation with notes on issues you encountered and how you fixed them—this will save time for future upgrades.
• Commit all changes to version control and tag the release to mark the successful upgrade.
