从EF Core 9.0 开始,如果模型与上次迁移相比有未决的更改,当调用 dotnet ef database update、Migrate 或MigrateAsync 时,将引发异常。上下文“DbContext”的模型具有挂起的更改。 在更新数据库之前添加新的迁移。 通过将事件 ID“RelationalEventId.PendingModelChanges
var blogs = await context.Blogs .OrderBy(s => EF.Functions.VectorDistance(s.Vector, vector)) .Take(5) .ToListAsync(); 有关详细信息,请参阅有关矢量搜索的文档。分页支持Azure Cosmos DB 提供程序现在允许通过延续令牌对查询结果进行分页,这比传统使用 Skip 和Take 更高效、更具成本效益:c#...
The interceptor has both sync and async methods. This can be useful if you need to perform async I/O, such as writing to an audit server. The interceptor allows SaveChanges to be skipped using the InterceptionResult mechanism common to all interceptors. The downside of interceptors i...

dispatch_sync dispatch_async dispatch_barrier_sync dispatch_barrier_async 我们的想法是读操作可以支持同步和异步,而写操作也能支持异步写入,并且必须确保是写入的是同一个引用。GCD 的 barrier 集合 APIs 提供了解决方案:他们将会一直等到队列中的任务清空,才会继续执行 block。使用 barrier APIs 可以用来限制我们对...
首先说下为什么会crash ,因为我定义的queue是串形队列,主要问题出在 dispatch_barrier_sync(queue, ^{ })会把block中的任务添加到queue的队列的尾部,而我外面包的 dispatch_async(queue, ^{ })block就是在这个queue中执行的,所以block的内容会在任务6执行完了才会执行,而sync又会把当前队列给堵塞住,所以crash了...

ComboboxEditor tries to preserve order during initSelection for async / sync sources. Add an optional hook for fetchScriptData that allows intercepting script data loading by fetch / xhr (sync) primarily for testing purposes.
