<system.web> <httpRuntime enableVersionHeader ="false" />
To remove X-AspNetMvc-Version from the header, you can modify the application_start event in Global.asax.cs as follows: protected void Application_Start()
{
MvcHandler.DisableMvcResponseHeader = true;
After making above changes in my app, the end result of the header looks like this:
