System.Reflection.Assembly.GetExecutingAssembly() always returns 0.0.0.0

Question

I have modified my assemblyinfo.cs with this:

[assembly: AssemblyVersion("1.0.*")]

and on the _layout.cshtml I put this so I can recognize in which build I am testing:

 @System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString()

it always prints 0.0.0.0

When I go to the bin folder and check the dll properties, version says 1.0.343.2323 so I dont get it?

Answer 1

Assembly name shown is of some runtime assembly loaded by IIS, instead use EntryAssembly if entry point for your application resides in the assembly for which you have updated the AssemblyInfo -

Assembly.GetEntryAssembly().GetName().Version.ToString();

In case it's different than the calling assembly you can do this way -

Assembly.GetAssembly(typeof(YourAssembly.AnyClass)).GetName().Version.ToString();

Answer 2

Looks like the executing assembly is not the one you've compiled, but a dynamic assembly created by IIS.

Try using

typeof(Your_Type_From_NonWeb_Assembly).Assembly.GetName().Version.ToString()
