Identifying the version of the dll’s  used on the backend is fairly simple. All we need is to iterate into the current directory and find the version of the dlls.  It is just a simple controller that receives via Dependency Injection the path to the current directory. It is no harder than that code:

 

[HttpGet]

public FileVersionInfo[] GetVersions([FromServices] IHostingEnvironment hosting)

{

var dirPath = hosting.ContentRootPath;

var ret = new List<FileVersionInfo>();

var files = Directory.EnumerateFiles(dirPath, "*.dll", SearchOption.AllDirectories).Union(Directory.EnumerateFiles(dirPath, "*.exe", SearchOption.AllDirectories));



foreach (string item in files)

{

try

{

var info = FileVersionInfo.GetVersionInfo(item);

ret.Add(info);

 

}

catch (Exception)

{

//TODO: log

}

}

return ret.ToArray();

}

}

In our days recognizing fast the version of the software you deploy it is important ( very important , if you do not have a continuum upgrade strategy – like Chrome does or in my days , using Click Once ). More, you should be able to recognize what components you are using in the software.

This was very interesting for me ( see http://msprogrammer.serviciipeweb.ro/2014/10/13/tt-add-more-informations-net-version-build/  and http://msprogrammer.serviciipeweb.ro/2019/01/14/opensource-library-versioning/ ). However, this is not about how to version the application – but how to display the version for BackEnd and FrontEnd components.

So – we need a front-end HTML page ( or WPF, or WinForm or other front-end ) and 2 informations  : 1 for the components for the backend and one for the components for the front end .

I have made such a component – it is made for Angular and .NET Core. It can be adapted very easy for all others , by transforming the  Angular library to a WebComponent library and the WEB API .NET Core into node.js  HTTP Rest.

If you want to see the final product , please check the https://www.npmjs.com/package/versions-netcore-angular  and the  live demo at https://azurestankins.azurewebsites.net/about

You will see the version of .NET Components and Angular Components that we are using.
