How to resolve entity framework configuration error in Web Forms?
When running an ASP.NET web application with NuGet packages in Visual Studio 2010, you may encounter the error “unrecognized configuration section 'EntityFramework'” in some cases.
Figure 1: Unrecognized Configuration Section EntityFramework
This error occurs because the project requires the Entity Framework package, which is not included by default in Visual Studio 2010. While Visual Studio 2012 and 2013 ASP.NET projects include Entity Framework by default, Visual Studio 2010 does not. To resolve this, you can manually install the Entity Framework package using the steps below.
- Click Tools->NuGet Package Manager->Package Manager Console from Visual Studio’s Menu.
Figure 2: Visual Studio Menu
- It opens the Package Manager console. Enter the following command in the console window.
PM> install-package EntityFramework
Figure 3: Package Manager
- This command downloads and installs the Entity Framework package into the project. You need to wait till the installation is finished. Now, you can run the application without the Entity Framework configuration error.
Note:
Visual Studio needs an active internet connection to install the Entity Framework package.
Note
A new version of Essential Studio for ASP.NET is now available. Versions released before Essential Studio 2014 Volume 2 are now referred to as classic. The updated ASP.NET suite is built on Essential Studio for JavaScript, offering client-side rendering with HTML5-JavaScript controls for improved performance and enhanced touch support. It includes all the features of the classic version, making migration simple and seamless.
The Classic controls can be used in existing projects; however, if you are starting a new project, we recommend using the latest version of Essential Studio for ASP.NET. Although Syncfusion® will continue to support all classic versions, we are happy to assist you in migrating to the newest edition.
For current customers, you can check out our components from the License and Downloads page. If you are new to Syncfusion®, you can try our 30-day free trial to check out our other controls. If you have any queries or require clarifications, please let us know in the comments section below.
