最近转换为 .NET Core 后，我在尝试使用我们的任何 AuthProviders 进行身份验证时收到以下错误：

“尝试从适配器'NetCoreContainerAdapter'解析服务'System.Boolean'时出错：对象引用未设置为对象的实例。”

我在 .NET Core 3.1 上使用 ServiceStack.Core 5.9.2。

你SgCredentialsAuthProvider在国际奥委会注册了吗？它只应该作为 AuthProvider 添加到您的AuthFeature插件注册中。

该错误表明您有一个自动装配的服务或具有公共bool属性或构造函数的依赖项，它试图注入从IsAccountLocked() 方法bool调用的不存在的依赖项：

public virtual bool IsAccountLocked(IAuthRepository authRepo, IUserAuth userAuth, IAuthTokens tokens=null)
{
    if (AccountLockedValidator != null)
        return AccountLockedValidator(authRepo, userAuth, tokens);
    
    return userAuth?.LockedDate != null;
}

从其实施来看，国际奥委会正试图解决AccountLockedValidator来自国际奥委会的每个通用参数并且在通用参数上失败bool：

public Func<IAuthRepository, IUserAuth, IAuthTokens, bool> AccountLockedValidator { get; set; }

SgCredentialsAuthProvider如果您正在对依赖项进行一些自动扫描/自动连接，则删除您的 IOC 注册或忽略它应该可以解决它。
