Entertain different things with .NET Core the second day. Almost coped with the Add-Migration , but here it appears

Add-Migration : Исключение при вызове "OpenFile" с "1" аргументами: "Параметр задан неверно. (Исключение из HRESULT: 0x80070057 (E_INVALIDARG))"строка:1 знак:1 + Add-Migration Arajan + ~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Add-Migration], MethodInvocationException + FullyQualifiedErrorId : ComMethodTargetInvocation,Add-Migration

What is it? I can not tolerate it. I cannot solve this riddle.

    Drive on this error. The fact is that it simply does not open the migration file for viewing. So then the migration is created. Do further Update-Database and you will be happy.
