Display project version in ASP.NET MVC Core application (RC2)

Question

How do I display application version from the project.json? I am using gulp-bump to autoincrement version, but I can't show the recent version. Here is what I'm trying:

@(Microsoft.Extensions.PlatformAbstractions.PlatformServices.Default.Application.ApplicationVersion) 

This does not work, it displays "1.0.0" instead of real value from project.json

I also tried this but it looks like it is no longer works in RC2:

@inject Microsoft.Extensions.PlatformAbstractions.IApplicationEnvironment appEnv My version number is @(appEnv.ApplicationVersion) 

Answer 1

Since Platform Abstractions were obly shipped with ASP.NET Core 1 and has been removed from ASP.NET Core 2 and up, if you're using version 2 or above, you must replace this row:

Microsoft.Extensions.PlatformAbstractions.PlatformServices.Default.Application.ApplicationVersion 

with this one:

System.Reflection.Assembly.GetEntryAssembly().GetName().Version 

as specified in "Replacing API usage" section of the previous linked page.

Answer 2

As per this announcement, IApplicationEnvironment no longer exists.

You can still access the ApplicationVersion statically using:

Microsoft.Extensions.PlatformAbstractions.PlatformServices.Default.Application.ApplicationVersion

It works for me. My project.json looks like this:

{     "version": "1.0.0.2",     // all the rest } 

And in my index view, I have the following line at the top:

@Microsoft.Extensions.PlatformAbstractions.PlatformServices.Default.Application.ApplicationVersion 

And I correctly get 1.0.0.2 in the output. And when I change that value and restart (build) the application, the new version is shown there.
