Everytime I try to add new script to any prefab Im getting this message

"Can't add script component because the script class cannot be found. Make sure there are no compile errors"

And yes the file name matches.

I'm using the latest version currently 2018.3.5f1

I was using recently "Unity C# 5.0 and 6.0 Integration" from here because I was having this kind of error in the console

"error CS1644: cannot be used, because it is not part of the C# 4.0 language specification."

After that not knowing how to uninstall this I removed the folder and reimported the asset

Now I'm having this error which causing me the script component add, supposedly

UnityEditor.Scripting.Compilers.ScriptCompilerBase.BeginCompiling () (at C:/buildslave/unity/build/Editor/Mono/Scripting/Compilers/ScriptCompilerBase.cs:60) UnityEditor.Scripting.ScriptCompilation.CompilationTask.QueuePendingAssemblies () (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/CompilationTask.cs:228) UnityEditor.Scripting.ScriptCompilation.CompilationTask.Poll () (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/CompilationTask.cs:135) UnityEditor.Scripting.ScriptCompilation.EditorCompilation.CompileScriptAssemblies (UnityEditor.Scripting.ScriptCompilation.ScriptAssembly[] scriptAssemblies, UnityEditor.Scripting.ScriptCompilation.ScriptAssemblySettings scriptAssemblySettings, System.String tempBuildDirectory, EditorScriptCompilationOptions options, CompilationTaskOptions compilationTaskOptions, CompileScriptAssembliesOptions compileScriptAssembliesOptions) (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilation.cs:1133) UnityEditor.Scripting.ScriptCompilation.EditorCompilation.CompileCustomScriptAssemblies (UnityEditor.Scripting.ScriptCompilation.ScriptAssemblySettings scriptAssemblySettings, System.String tempBuildDirectory, EditorScriptCompilationOptions options, BuildTargetGroup platformGroup, BuildTarget platform) (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilation.cs:1045) UnityEditor.Scripting.ScriptCompilation.EditorCompilation.CompileCustomScriptAssemblies (EditorScriptCompilationOptions options, BuildTargetGroup platformGroup, BuildTarget platform) (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilation.cs:1039) UnityEditor.Scripting.ScriptCompilation.EditorCompilationInterface+c__AnonStorey4.<>m__0 () (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilationInterface.cs:277) UnityEditor.Scripting.ScriptCompilation.EditorCompilationInterface.EmitExceptionAsError[Boolean] (System.Func`1 func, Boolean returnValue) (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilationInterface.cs:97) UnityEditor.Scripting.ScriptCompilation.EditorCompilationInterface:CompileCustomScriptAssemblies(EditorScriptCompilationOptions, BuildTargetGroup, BuildTarget)

Any ideas ?

error CS1644: cannot be used, because it is not part of the C# 4.0 language specification -> make sure you are using .Net4.X not .Net3.5 in PlayerSettings->Others->Scripting Backend. Make also sure the component class has exactly the same name as the script file - derHugo
I did doesn't resolve the last error mentioned - user10003487
Could you post your script somewhere? - derHugo
I would have to know first which one it is causing the issue - user10003487
Oh I see .. I read for some people the only solution was to reinstall Unity .. might be a bug? - derHugo
