Azure Functions Scoped 实例已被处置且不再可用
Azure Functions Scoped instances are disposed and no longer available
当函数应用程序在 运行-time 版本“2.0.12701.0" (FUNCTIONS_EXTENSION_VERSION = ~2 in App Settings) 上 运行ning 时，我收到以下错误。一旦我在应用程序设置中更改 FUNCTIONS_EXTENSION_VERSION to 2.0.12673.0 . 功能开始工作，无需任何代码更改或部署。
错误：

更改应用程序设置中的功能 运行-时间版本 (FUNCTIONS_EXTENSION_VERSION =2.0.12673.0) 从默认 运行-时间版本 2.0.12701.0 修复了问题。
这是我的 Function App Startup class，它注册了依赖项。
public class FunctionAppStartup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
var config = new ConfigurationBuilder()
.SetBasePath(Environment.CurrentDirectory)
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
.AddJsonFile("secret.settings.json", optional: true, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
builder.Services.Configure<ConfigurationManager>(x => config.Bind(x));
builder.Services.AddSingleton<Contracts.IConfiguration>(resolver =>
resolver.GetRequiredService<IOptions<ConfigurationManager>>().Value);
builder.Services.AddScoped<IChannelAdapter, ChannelAdapter>();
builder.Services.AddScoped<ITableStorageManager, TableStorageManager>();
builder.Services.AddSingleton<IDatabaseContext, DatabaseContext>();
builder.Services.AddScoped<IJobRepository, JobRepository>();
}
}
期望我的函数应用程序在最新的 运行 版本上运行 运行，而不是我针对较小的 运行 版本。
从现在开始，您无法使用此运行时版本。
因为即使这是最新发布的版本，但它还没有更新到生产站点。请检查 release note.
Note: This release is not yet in production but will be deploying over the next few days. These release notes will be updated when it has been deployed to all production sites.
更新时，官方会更新说明。所以最新的可用版本是 2.0.12673.
