How to check asp.net version of the website ?

Question

Please let me is there any way to find the ASP.Net version of Asp.net website and .Net Core websites?

Answer 1

Hi @Venkat ,
About the asp.net version,you could create a new page and write below codes:

Response.Write("Version: " + System.Environment.Version.ToString());  

About the asp.net core version,what do you want of .NET Core SDK version,.NET Core information,the installed runtimes or the installed SDKs. You could write following commands.

dotnet --version      // Display .NET Core SDK version.  
  
dotnet --info          //Display .NET Core information.  
  
dotnet --list-runtimes   // Display the installed runtimes.  
  
dotnet --list-sdks       // Display the installed SDKs.  

You can view all .NET Core versions Installed on the system by navigating to the installation folder on below path.

%ProgramFiles%\dotnet\sdk  

Also you could check in Solution Explorer. Open the right-click menu for the project that you want to check, and choose Properties, then select Application tab > Target framework.

HI @Venkat
You can use a third party browser plugin to find the ASP.NET version.
Plugin
http://builtwith.com/toolbar
This plugin is available for most of the popular browsers like Firefox, Chrome and Safari except IE, when I write this post. Just include this on your browsers, and you can find out the technology behind with the currently rendered on the browser.

Using Developer Toolbar:

IE doesn’t require any plugins or add-ons. You can find the technology behind this using the built-in tool called “IE Developer Toolbar”. This toolbar, contains a tab called “Network”. In this tab, you can find the necessary details.
