How to assign icon to script file that just got created in Unity3D?

I am trying to figure out on how to assign icon to a script file that just got created in Unity, but with no success so far.
I created this EditorWindow class that allows me to create a new c# class with some custom template.
After I created the file I save the asset like this
AssetDatabase.ImportAsset(filePath, ImportAssetOptions.ForceUpdate);
AssetDatabase.SaveAssets();
AssetDatabase.Refresh();
After the script is created I want to also assign the custom icon automatically. Something like if you create a script named GameManager, unity automatically assigns custom icon for that script file.
I created AssetPostprocessor class that checks if the new asset is created under a specific path change the icon for that file.
The problem is that when I tried to test this Unity crashed for me. So I am running out of ideas a bit..
using System;
using System.Reflection;
using UnityEditor;
using UnityEngine;
public class Script_Importer : AssetPostprocessor
{
void OnPreprocessAsset()
{
if (assetPath.Contains("Scripts/CustomScripts/"))
{
AssetImporter asset = (AssetImporter)assetImporter;
var obj = AssetImporter.GetAtPath(assetPath) as UnityEngine.Object;
AssignLabel(obj);
}
}
void AssignLabel(UnityEngine.Object obj)
{
Texture2D tex = EditorGUIUtility.IconContent("Script_Icon").image as Texture2D;
Type editorGUIUtilityType = typeof(EditorGUIUtility);
BindingFlags bindingFlags = BindingFlags.InvokeMethod | BindingFlags.Static | BindingFlags.NonPublic;
object[] args = new object[] { obj, tex };
editorGUIUtilityType.InvokeMember("SetIconForObject", bindingFlags, null, null, args);
}
}

C# for scripting (csx) location of script file

In F# it's rather easy with predefined identifier __SOURCE_DIRECTORY__
https://stackoverflow.com/a/4861029/2583080
However this identifier does not work in C# scripting (csx files or C# Interactive).
> __SOURCE_DIRECTORY__
(1,1): error CS0103: The name '__SOURCE_DIRECTORY__' does not exist in the current context
Getting current directory in more traditional way will not work either.
Directory.GetCurrentDirectory()
Returns: C:\Users\$USER_NAME$\
new Uri(System.Reflection.Assembly.GetExecutingAssembly().CodeBase).LocalPath;
Returns: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\ManagedLanguages\VBCSharp\InteractiveComponents\

In C# you can take advantage of caller information attributes (available since C# 5 / VS2012). Just declare a method like this:
string GetCurrentFileName([System.Runtime.CompilerServices.CallerFilePath] string fileName = null)
{
return fileName;
}
And call it without specifying the optional parameter:
string scriptPath = GetCurrentFileName(); // /path/to/your/script.csx

In csx, you are can add ExecutionContext as a parameter and access FunctionDirectory from it like so:
using System;
using Microsoft.Azure.WebJobs;
public static void Run(TimerInfo myTimer, ExecutionContext executionContext, ILogger log) {
var dir = executionContext.FunctionDirectory;
log.LogInformation($"Directory: {dir}");
}
ExecutionContext.FunctionDirectory will return the directory the contains the function's function.json file. It doesn't include the trailing .
At this time this seems to be the best documentation for ExecutionContext.
I am trying to find the answer to this question myself, and this was my previous answer.
In csx, the following helper method will return the directory "of the source file that contains the caller".
using System.IO;
...
public static string CallerDirectory([System.Runtime.CompilerServices.CallerFilePath] string fileName = null)
{
return Path.GetDirectoryName(fileName);
}
To call it, don't specify the fileName parameter.
var dir = CallerDirectory();

CodeDom using WPF - error at runtime

I have a project where I compile a lot of files in memory using Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider
My problem happened when I started to try to use wpf windows.
I am able to get the in-memory assembly to compile, but when I go to bring up the window I get:
System.Exception: The component 'Dynamic.DragonListForm' does not have
a resource identified by the URI
'/ScriptCode;component/wpf_ui/dragonlistform.xaml'.
at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
NOTE: I compile by adding a list of all the .cs files in a particular folder
objCompileResults = objCodeCompiler.CompileAssemblyFromFile( objCompilerParameters, files.ToArray() );
I also add dll references needed to make it work.
NOTE: Thanks to Reed, I was able to get it working well enough for my needs by doing:
List<string> bamlFiles = Directory.GetFiles( directoryPath, "*.baml", SearchOption.AllDirectories ).ToList();
bamlFiles.ForEach( x => objCompilerParameters.EmbeddedResources.Add( x ) );
In my project this is good enough. I have a .NET app that I use for executing voice commands. In general, I have it so I can recompile assembly changes in memory as I change voice commands. I imagine some of this won't work with WPF but I am now able to use WPF windows in my in-memory assembly.

The problem is that WPF files aren't just C#, they're also the XAML, which then gets compiled in a separate MSBuild task into BAML resources and included as embedded resources.
If you wanted to support some version of this, you'd need to include all of the referenced xaml as resources. See this post for details on how to do that using CodeDom.
Once that was done, you'd have to also make sure that you're using a compatible mechanism for loading the types. The "normal" way C# compiles xaml/xaml.cs files won't work in your situation, as it requires the resources to be precompiled to baml. You'd have to effectively "rewrite" the code behind for the C# types to use a different mechanism of loading the XAML - typically this would be done by using XamlObjectReader and XamlObjectWriter to read the xaml contents and "write them" into the object during the InitializeComponent pass.

Another very helpful piece of information is given at: The component does not have a resource identified by the uri
From that I created an extension method that can be called like this:
// https://stackoverflow.com/questions/7646331/the-component-does-not-have-a-resource-identified-by-the-uri
this.LoadViewFromUri( #"/ScriptCode;component/wpf_ui/spywindowviewer.xaml" );
// InitializeComponent();
NOTE: I just use the uri that shows up in the error message, for example:
The component 'Dynamic.DragonListForm' does not have a resource identified by the URI '/ScriptCode;component/wpf_ui/dragonlistform.xaml'. at
The extension method:
using System;
using System.IO.Packaging;
using System.Linq;
using System.Reflection;
using System.Windows;
using System.Windows.Markup;
using System.Windows.Navigation;
namespace Extensions
{
public static class WpfWindowExtensions
{
// https://stackoverflow.com/questions/7646331/the-component-does-not-have-a-resource-identified-by-the-uri
public static void LoadViewFromUri( this Window window, string baseUri )
{
try
{
var resourceLocater = new Uri( baseUri, UriKind.Relative );
// log.Info( "Resource locator is: ")
var exprCa = ( PackagePart )typeof( Application ).GetMethod( "GetResourceOrContentPart", BindingFlags.NonPublic | BindingFlags.Static ).Invoke( null, new object[] { resourceLocater } );
var stream = exprCa.GetStream();
var uri = new Uri( ( Uri )typeof( BaseUriHelper ).GetProperty( "PackAppBaseUri", BindingFlags.Static | BindingFlags.NonPublic ).GetValue( null, null ), resourceLocater );
var parserContext = new ParserContext
{
BaseUri = uri
};
typeof( XamlReader ).GetMethod( "LoadBaml", BindingFlags.NonPublic | BindingFlags.Static ).Invoke( null, new object[] { stream, parserContext, window, true } );
}
catch( Exception )
{
//log
}
}
}
}

Thanks in advance.

Not sure if you found an answer to your question, but Orca is an MSI Table editor that is included in the Windows SDK.
For Windows 7 and .NET 3.5 SP1 - https://www.microsoft.com/en-us/download/confirmation.aspx?id=3138
Once installed, navigate to C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin
and execute the orca.msi. You will then run your Wix# project to generate the msi file. Open the msi file with Orca and navigate to the Binary table. Double click on the data column for WixSharp_LicenseFile and you will be given an option to read or write to a file. If you want to see the contents, select a file name (.rtf format) and write to file. Make any changes you wish, or replace that file, and then use it to read into that binary data row. Once you have read it into the msi table, save the msi file and close.
I am new to WixSharp myself, so I have not found another way (yet!), but this worked for me.
Good luck!

This is the error I receive after doing all that is mentioned in the screenshots below and doing some R&D. The directory mentioned "C:\Program Files (x86)\\.config" exists when the encryption custiom action is being called but it throws an exception.

Yes, it can be done with following steps:
1- write your required functionality in c# installer class (make sure your are using installer class)
2- Compile and add your dll into installshield (recomended create a separate component for this dll)
3- Select component view -> select above component and go to .Net settings section, set the ".Net Installer class" to true. Set the ".net installer class parameters"
Parameters are passed as key/value pair e.g
/targetDirectory="[INSTALLDIR]\"
All steps are same, just added screenshots.
Create a dll with an installer class and your encrypt/decrypt class.
Add dll and config file to component(above mentioned), if config file is already added to some other component then its fine. no need to add again.
I have added and retrieved INSTALLDIR variable as argument which is predefined. if you want to receive some input from user (from some custom textboxes) then you will need to define your own variables to store and pass values as arguments.
Creating dll with installer class and your requred logic for other task
Creating component and adding files
Mark the dll as installer class and pass arguments
Here goes installer class:

//Debugger.Break();
installationDirectory = Context.Parameters["INSTALLDIR"];
//I believe, the config file must be located in the installation directory if so, then use the following way to compute path
string configFilePath = Path.Combine(installationDirectory, "myConfigFile.config");
EncrptionHelper.SetValue(configFilePath, "testKey", "testValue");
}
catch (Exception ex)

System.Diagnostics.Debug.WriteLine(ex.Message);

I think installshield cannot (or need extra work) for read your assemblies, but you can run simple console application which consume your assemblies from installscript and passing parameter from installshield.
Create simple console application
Include console application on Support Files
Copy to installation folder or assemblies location, so console application can access your assemblies
Launch from installscript using launchappandwait
If consoleapp.exe not use anymore, just delete it.
