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

Question

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?

Answer 1

Via Reflection:

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

Answer 2

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):

How do I determine which version of ASP.NET MVC is installed on my system?

For MVC 4.0, MVC 5.0, or MVC 5.1 you should have deployed the affected binary (System.Web.MVC.dll) with your application. 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.

Answer 3

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"

Answer 4

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

.

Answer 5

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:

Answer 6

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.
