![]() The problems here may vary greatly, but here's one example from my most recent project: dotnet ef migrations add Initial This is a tiny bit more complicated, but it's also much rarer that you will need to do this (unless you're developing your own providers or Entity Framework extensions). NET exception is thrown to investigate the issues in-depth. Now you can either set up your own breakpoints or have your debugger pause the application when any.

Let's start with the easier part - debugging the situation when errors appear while changes to the database are being applied, e.g. It's also best to have the same DbContext configuration here as in the project that you're having problems with. Remember to reference the correct DbContext for which the database update phase fails. The Host bits might look strange, but the setup is there to easily inject the IServiceScopeFactory, which will be used to set up instances of the DbContext. Protected override Task ExecuteAsync(CancellationToken stoppingToken) _serviceScopeFactory = serviceScopeFactory Public Worker(IServiceScopeFactory serviceScopeFactory, IHost host, ILogger logger) Private readonly IServiceScopeFactory _serviceScopeFactory Log.AddFilter("Microsoft", level => level >= LogLevel.Warning) Options.UseSqlServer("Server=127.0.0.1,1433 Database=Database User ID=User Password=Password MultipleActiveResultSets=true")) Var host = Host.CreateDefaultBuilder(args) * or other EFCore package depending on your database engineĪnd Program.cs looking like this: using EFCoreDebug ![]() NET 6 console application with the following NuGet packages added: * They usually work great (besides the occasional conflicts when merging pull requests), but there might come a time when you need to debug either the migration scaffolding operation or applying the changes to the database - what to do then? It is easier than you might think! Starting pointĪs a starting point, let's create a simple. Using this way you will be able to apply stored procedure migrations if you’re getting them as files also it will help you to keep your C# migration scripts clean.Entity Framework's Migrations are a powerful tool for keeping the application data model in sync with the database. ![]() FromSqlInterpolated ( $"usp_GetAllTodoItemsByStatus You can execute a stored procedure in Entity Framework with the help of FromSqlInterpolated method. If you’re using Entity Framework Code first approach there is no direct way to create stored procedure in C# code. The stored procedure can accepts input parameters and executes the T-SQL statements in the procedure, can return the result. SQL Server stored procedure is a set of SQL statements grouped as a logical unit and stored in the database. Stored Procedure in Entity Framework Core Migrations ![]()
