11/30/2023 0 Comments Ef core log all commands callsNeat, but apparently we didn’t have any control over this Log. If we look into the Debug Console, we’ll see it executed a “SELECT TOP(2)…” (hmm… wonder why) query, that had the input parameter value of 1 and took 72ms to execute (in the following case) using the SqlDataReader. Now when we run the application and navigate to the Details page, our Logger method is invoked thrice, once for the Find query, once when execution starts and finally when execution is complete. Whenever EF needs to Log, it will call our Logger function, which essentially logs to the Debug console. So we add a Logger function and assign it to the db.Database.Log. We can update our PostsController.cs and add Logging for the Details action method to view the query that EF is firing when we do a db.Posts.Find(id). Enabling DebuggingĮnabling debugging is as simple as assigning an action method that takes a string parameter as we can see below: Trying to analyze complex EF queries if they are not returning expected results. Digging into see unexpected behavior of some of your queries that might be long running unexpectedly A means of understanding how EF is translating LINQ to SQL The DB Logging capability aims to provide: EF now provides this ability natively now. Earlier we have seen two excellent ASP.NET components in MiniProfiler and Glimpse that gave us details of what kind of Queries are being executed. Monitoring EF activity with the new DB Logging capabilitiesĭB Logging implies monitoring the interactions between EF and the Database. All you have to do is in the Package Manager Console, type in the following:Ĭompile and you should be good to go, unless you were using APIs that are no longer supported (here are the release notes). ![]() Once you have the solution loaded in Visual Studio 2013 (Preview at the moment), updating from EF6 Beta to RC 1 is pretty easy. You can clone the code from the GitHub Repo or download the zip archive directly. We’ll start off with the Solution from our previous article. Entity Framework 6 has gone from Beta to Release Candidate 1 since we last posted our ‘what’s new’ article, so today we’ll see how to upgrade from Beta to RC 1 and then take a look at two new EF 6 features, DB Logging and Mapping CRUD operations to Stored Procedures directly.
