Intermittent error with EF Core: The connection does not support MultipleActiveResultSets

阅读更多关于 Intermittent error with EF Core: The connection does not support MultipleActiveResultSets

问题 I have an ASP.Net Core application that uses EF Core. I use ASP.Net Identity and share the same DBContext for my app's entities. I have set my connection string to an Azure SQL database to have MultipleActiveResultSet=True. It works for a day or two, but eventually it fails with the error: The connection does not support MultipleActiveResultSets. I don't think MARS is the real issue since it worked for the first two days it was up. I am using ASP.Net Core's built-in DI to set my DbContext.

Using a migration tool I found on the web, it has highlighted some issues where features are unavailable in Azure, the main one being BULK INSERT.

What alternatives exist to using guid as clustered index on tables in SQL Azure (Federations)

阅读更多关于 What alternatives exist to using guid as clustered index on tables in SQL Azure (Federations)

问题 I am currently working on a project that entails using a SQL Azure database to store data for a forthcoming application.
