3. InvalidOperationException: A second operation was started on this context before a previous operation completed. This is usually caused by different threads concurrently using the same instance of DbContext. For more information on how to avoid threading issues with DbContext, see https://go.microsoft.com/fwlink/?linkid=2097913.
Microsoft.EntityFrameworkCore.Internal.ConcurrencyDetector.EnterCriticalSection()
DbContext不允许用于多线程。所以在多线程场景下需要多实例。我选择实现多实例的方式是使用
DbContext factory
详见： https://docs.microsoft.com/en-us/ef/core/dbcontext-configuration/#avoiding-dbcontext-threading-issues
https://www.cnblogs.com/zhangjd/p/12039914.html
使用Factory可能会有如下No.4问题
4. Inner Exception 2:
InvalidOperationException: Unable to resolve service for type 'AF_XiMan.Data.MesDbContext' while attempting to activate 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserOnlyStore`6[Microsoft.AspNetCore.Identity.IdentityUser,AF_XiMan.Data.MesDbContext,System.String,Microsoft.AspNetCore.Identity.IdentityUserClaim`1[System.String],Microsoft.AspNetCore.Identity.IdentityUserLogin`1[System.String],Microsoft.AspNetCore.Identity.IdentityUserToken`1[System.String]]'.
该问题可以通过指定AddTransient
