ASP.NET Core is a new open-source, cross-platform framework for developing modern cloud-based internet-connected applications like web, IoT, and mobile backends. Apps written in ASP.NET Core can run on either.NET Core or the full.NET Framework. It was designed to provide an optimized development framework for programs that run on-premises or in the cloud. It's modular components with low overhead, giving you more options when building solutions. Your ASP.NET Core apps can be developed and operated on Windows, Mac, and Linux. The source code for ASP.NET Core is available on GitHub. ASP.NET Core is an evolution of ASP.NET, which first appeared in January 2002, during the dot-com bubble. The initial release of ASP.NET was a free package for web development on Windows servers. Today, there are three major versions of ASP.NET

The architectural improvements in ASP.NET Core result in a significantly leaner and modular framework. The system is no longer used in ASP.NET Core. Web.dll. It's built on a foundation of well-factored NuGet packages. It lets you optimize your program by including the NuGet packages you require. Tighter security, reduced servicing, improved performance, and lower expenses in a pay-for-what-you-use model are advantages of a smaller app surface area. The ASP.NET Core team designed their framework specifically to create cloud-ready apps that run anywhere. They wanted to create a framework that developers and IT administrators could use with confidence, even if they didn't know how to write code themselves.

ASP.NET Core 1.0 was released in December 2016, with the launch of Visual Studio 2017 not long after. That same month, Microsoft announced an SDK for .NET Standard 2.0, which enables cross-platform apps written in C#/VB or JavaScript for all major platforms:

ASP.NET Core validation DropdownList

The ASP.NET Core Dropdown List can be used to quickly replace HTML select tags. It has a rich design and lets users choose from a list of predetermined values a single non-editable value. Data binding, filtering, grouping, UI customization, accessibility, and preselected values are all included out of the box. The DropdownList is a flexible, easy to use control and can be used in many different scenarios. For example, you can use it to populate a drop-down or text box. Just bind an object property to the DataSource property of the DropdownList, and then set the SelectedValue to the desired value in your view model.

There are two ways to validate a DropDownList value:
1. Validation Rules
By adding validation properties to the input element, validation rules assist you in verifying the selected text. The ValidationRules property can be used to set this. You may use any of the built-in validation rules or create your own.
2. Messages of Validation
The ValidationMessage property allows you to create your own unique error message. Specify the corresponding annotation attribute followed by the message to display the error message.
The DropdownList allows you to bind an object property to the DataSource property of the DropDownList, and after that, set the SelectedValue to a value in your view model. If not set prior, the selected value will be initialized by default with a default option '.
