Why would Assembly.GetExecutingAssembly() return null?

should help you out This is a perfect example of why it's an almost universally bad idea to eat exceptions, especially the top-level System.Exception. The problem could be anywhere; more likely than not, the real problem is in your logging code.
Take out those empty catch blocks (or rethrow inside them with throw;) and see where the exception is really occurring. And once you find the real problem and rewrite your code, rewrite it to catch only exceptions that you actually know how to handle.

Assembly.GetExecutingAssembly() performance

may help you . The question of the performance overhead and whether it is significant is really dependent on how much it is accessed. On a single page hit, probably not - the code execution time being measured in some ms. If the server is under load with lots of hits, quite possibly.
But can't you just make the hit once anyway (i.e. still use reflection, but not every time):
code :
public class AppVersion
{
    private static readonly Version _applicationVersion = Assembly.GetExecutingAssembly().GetName().Version;

    public static Version ApplicationVersion
    {
        get { return _applicationVersion; }
    }
}
var version = AppVersion.ApplicationVersion

.Net assembly override the Assembly.GetExecutingAssembly().CodeBase/Location of an external assembly

it fixes the issue There's no reasonable way to change GetExecutingAssembly.CodeBase or Location. If you don't have source for the assembly in question, your only solution is to copy your assembly to c:\ABC

WCF and Assembly.GetExecutingAssembly

like below fixes the issue You are correct in that it's not serialized as you expect.
class Assembly implements ISerializable
code :
public override void GetObjectData(SerializationInfo info, StreamingContext context)
{
  if (info==null)
    throw new ArgumentNullException("info");

  Contract.EndContractBlock();

  UnitySerializationHolder.GetUnitySerializationInfo(info,   UnitySerializationHolder.AssemblyUnity, 
  this.FullName, 
  this);
}

internal static void GetUnitySerializationInfo(
            SerializationInfo info, int unityType, String data, RuntimeAssembly assembly)
{
  info.SetType(typeof(UnitySerializationHolder));
  info.AddValue("Data", data, typeof(String));
  info.AddValue("UnityType", unityType);

  String assemName;

  if (assembly == null) 
     assemName = String.Empty;
  else 
     assemName = assembly.FullName;

  info.AddValue("AssemblyName", assemName);
}

Can't retrieve fully-qualified assembly name using Assembly.GetExecutingAssembly().GetName()

wish help you to fix your issue System.Reflection.Assembly.GetExecutingAssembly().GetName().Name gives you a name of the assembly. Usually it is the name of the file where assembly is located.
In other words, you could have assembly named Abcde.dll and have namespace My.Namespace.Name.Inside.Of.Abcde.Assembly. They are not related. And project's default namespace is... hm, it is a default. It doesn't get compiled into resulting assembly. It is just a Hint for Visual Studio which namespace it should place a class/interface/whatever to if you adding new item to this concrete project.

Difference between Assembly.GetExecutingAssembly() and typeof(program).Assembly


By : Paul

With these it helps Assuming program is in the executing assembly, they should both return the same value. However, typeof(program).Assembly should have better performance, since Assembly.GetExecutingAssembly() does a stack walk. In a micro benchmark on my machine, the former took about 20ns, while the latter was 30x slower at about 600ns.
If you control all the code I think you should always use typeof(program).Assembly. If you provided source code that other people could build into their assemblies, you would need to use Assembly.GetExecutingAssembly().
