    Since b11, I get this error on each compile and/or play:

    Unloading broken assembly Packages/com.unity.incrementalcompiler/Editor/Plugins/Unity.PureCSharpTests.dll, this assembly can cause crashes in the runtime

    I tried deleting the package cache and starting from scratch but it keeps popping. Doesn't happen with b10 and below.

    Happens with a new blank project with the IncrementalCompiler package installed.

    Same here, I get the error when trying to get assemblies for some reflection work using "System.Assembly.GetTypes();" using latest build 29 as well.

    Code (CSharp):
    1.  
    2. using System.Reflection;
    3. using System.Collections.Generic;
    4. using System;
    5. using UnityEngine;
    6.  
    7. public static class ReflectionHelpers
    8. {
    9.     public static System.Type[] GetAllDerivedTypes<T>(this System.AppDomain aAppDomain)
    10.         where T : MonoBehaviour
    11.     {
    12.         var result = new List<System.Type>();
    13.         var assemblies = aAppDomain.GetAssemblies();
    14.         foreach (var assembly in assemblies)
    15.         {
    16.             //Debug.Log(assembly.Location);
    17.             /* Workaround commented out to reproduce error
    18.             try
    19.             {
    20.                 if (assembly.Location.Contains("PackageCache"))
    21.                     continue;
    22.             } catch { continue; }
    23.             */
    24.  
    25.             var types = assembly.GetTypes();
    26.             foreach (var type in types)
    27.             {
    28.                 if (type.IsSubclassOf(typeof(T)) && !type.IsAbstract && type.IsClass)
    29.                     result.Add(type);
    30.             }
    31.         }
    32.         return result.ToArray();
    33.     }
    34. }

    Using 2018.3.11 and p.29, error is constantly present, but hasn't caused any issues for me so far.

    This is caused by a breaking change in one of Unity's internal API.
    I've released version `0.0.42-preview.30` which works with 2018.3.b11++, but breaks compatibility with previous 2018.3 betas.
    For support for 2018.3.b10 and lower, please use 0.0.42-preview.29.

    Dom, have one question. May I ask you what compiler command line tool in unity installed directory you use to compile NET4.x or NETSTANDARD2.0 assemblies? Like Unity.app/Contents/??? In the past we used mcs but that has change with the new 2018.3.

    The fix works but the incremental compiler takes ages to compile things compared if I remove it.
