NotSupportedException: Microsoft.CSharp.CSharpCodeProvider::.ctor error

Question

It works without errors in the editor.

But in post-build debugging I get that error.

I don't know how to fix it.

Any help would be appreciated

An error occurred in that code.

 using UnityEngine;
 using System;
 using Microsoft.CSharp;
 using System.CodeDom.Compiler;
 using System.Reflection;
 using System.Text;
 
 public class test : MonoBehaviour
 {
     private void Start()
     {
         var assembly = Compile(@"
             using UnityEngine;
             using System.Collections;
 
             public class RuntimeCompiled : MonoBehaviour
             {
                 public static RuntimeCompiled AddYourselfTo(GameObject host)
                 {
                     return host.AddComponent<RuntimeCompiled>();
                 }
 
                 void Start()
                 {
                     Debug.Log(""TEST"");
                 }
             }");
 
         var runtimeType = assembly.GetType("RuntimeCompiled");
         var method = runtimeType.GetMethod("AddYourselfTo");
         var del = (Func<GameObject, MonoBehaviour>)
             Delegate.CreateDelegate(
             typeof(Func<GameObject, MonoBehaviour>),
             method
             );
 
         // We ask the compiled method to add its component to this.gameObject
         var addedComponent = del.Invoke(gameObject);
 
         // The delegate pre-bakes the reflection, so repeated calls don't
         // cost us every time, as long as we keep re-using the delegate.
     }
 
     public static Assembly Compile(string source)
     {
         // Replace this Compiler.CSharpCodeProvider wth aeroson's version
         // if you're targeting non-Windows platforms:

         var param = new CompilerParameters();
 
         // Add ALL of the assembly references
         foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
         {
             param.ReferencedAssemblies.Add(assembly.Location);
         }
 
         // Or, uncomment just the assemblies you need...

         // This assembly contains runtime C# code from your Assets folders:
         // (If you're using editor scripts, they may be in another assembly)

         // Generate a dll in memory
         param.GenerateExecutable = false;
         param.GenerateInMemory = true;
 
         // Compile the source
         var result = provider.CompileAssemblyFromSource(param, source);
 
         if (result.Errors.Count > 0)
         {
             var msg = new StringBuilder();
             foreach (CompilerError error in result.Errors)
             {
                 msg.AppendFormat("Error ({0}): {1}\n",
                   error.ErrorNumber, error.ErrorText);
             }
             throw new Exception(msg.ToString());
         }
 
         // Return the assembly
         return result.CompiledAssembly;
     }
 }
