The recommended way to use Entity Framework 6 in an ASP. See the sample Visual Studio solution with EF6 and ASP. This is the connection string that the command-line tools will use.

NET Core application is to put the EF6 context and model classes in a class library project that targets the full framework. You'll want to implement a strategy to ensure that the class library uses the same connection string that the calling application uses.

This page describes some common problems that may arise when you deploy an ASP. For each one, one or more possible causes and corresponding solutions are provided.

The scenarios shown apply to both Azure and third-party hosting providers.

When you start getting build failures, it's useful to look here to make sure that the package you are using actually works on that target platform.

The output shows all of the assemblies passed into the compiler from packages and project references.

By Paweł Grudzień, Damien Pontifex, and Tom Dykstra This article shows how to use Entity Framework 6 in an ASP. To use Entity Framework 6, your project has to compile against . NET Core projects don't support all of the functionality that EF6 commands such as is only available in Entity Framework Core. NET Core project, in which case your context constructor must have a parameter that lets you pass in the connection string. Since your EF6 context doesn't have a parameterless constructor, your EF6 project has to provide an implementation of IDb Context Factory.

NET Framework, as Entity Framework 6 does not support . If you need cross-platform features you will need to upgrade to Entity Framework Core. If you need to do reverse engineering of a database into an EF6 model, see Code First to an Existing Database. The EF6 command-line tools will find and use that implementation so they can instantiate the context. implementation passes in a hard-coded connection string.

This tutorial series shows you how to deploy (publish) an ASP.

Notice in the above image, there is a flag: These errors also show up in Visual Studio in the package manager log output window: Read more about Nu Get.config here to learn about how packages sources work and how they affect your application.

When dependencies are unresolved, running the application will give you this: dnx . Invalid Operation Exception: Failed to resolve the following dependencies for target framework 'DNX, Version=v4.5.1': Newtonsoft.

I answered a question on stackoverflow that started to turn into a brain dump of the debugging techniques we've learnt while building this brand new stack. This project system is brand new (written from scratch), the Nu Get client is new, the dnx is new and evolving quickly. We have plans to make it so that packages can mark the minimum dnx that they require to run to make the error message more clear. Within visual studio, there is a process that runs called the Design Time Host.

While everything is still evolving, here's that answer reposted here as a blog post (slightly modified). When things go bad it's easy to throw your hands up and complain (please keep complaining), but with a little help and practice, you'll be diagnosing problems like a pro in no time (and sending pull requests! Also as time goes by, the breaking changes will die down and this issue will fade away... It's an instance of the DNX that Visual Studio and Omnisharp use to drive intellisense and diagnostics for based projects.
