How to determine the current version of ASP.NET MVC?

Is there a way to get the current version of ASP.NET MVC in code? Reflecting on MVC assemblies is needed? Any new IIS server variables? Some property to read in HTTP context?

1. Go to your References folder
2. Look for System.Web.Mvc
3. Right Click on it
4. Click Properties
5. Look at the Version property.

This is most likely your version but the GAC may play a role in messing you around.

Via Reflection:

typeof (Controller).Assembly.GetName().Version

Open the packages.config in your solution explorer..

Then look for ASP.NET MVC package ID, as follows:

id="Microsoft.AspNet.Mvc" version="5.2.2" targetFramework="net452"

At runtime-

string mvcVersion = typeof (Controller).Assembly.GetName().Version.ToString();

At design time-

• Go to your reference folder
• look for system.web.mvc
• Right Click on it
• Click Properties Look at the Version property

.

On the off chance you do not have access to the code and/or want to determine the version of ASP.NET that has been deployed on a machine, you can do the following (from TechNet):

Check your > application’s bin folder for the version of the binary. For MVC 2.0, > MVC 3.0, or MVC 4.0, refer to the Add or Remove Programs control panel > item for the version of MVC installed.

You can also check version of Microsoft.AspNet.Mvc nuget package installed in your project.

You can use Package Manager Console:

Get-Package Microsoft.AspNet.Mvc

This is another way of finding the MVC version for ASP net CORE projects by adding small code to your Home Controller. Hope this will be helpful.

Go to the Project Controller folder, open 'HomeController.cs' file. In HomeController.cs file, there is an Index Method with the return type of ActionResult/IActionResults. Just change the Method type from ActionResult to string and write the code, given below, into that method.

return typeof(Controller).Assembly.GetName().Version.ToString ();

Run your project, You can see the MVC version used in your project on the home page.

Use NuGet package MvcDiagnostics that you can install. Create an MVC "hello world" or some other basic program, then install this package. The installation will prompt for the project to add a file to. Confirm and you should see MvcDiagnostics.aspx added to your project. Right click on this file in the solution viewer, then choose "View in browser". You should then see a nice page with all your assembly information. Mine looks like the following:
