EF Core error
From Logic Wiki
Problem
When I run Add-Migration or update-database commands in PM I get these errors.
Add-Migration : Exception calling "Substring" with "1" argument(s): "StartIndex cannot be less than zero.
Parameter name: startIndex"
At line:1 char:1
+ Add-Migration -Name 'Firstqa' -verbose
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Add-Migration], MethodInvocationException
+ FullyQualifiedErrorId : ArgumentOutOfRangeException,Add-Migration
Explanation
When the project structured like
- .NET CORE
- MySql (SapientGuardian)
- StructureMap
Structuremap obviously try to auto fill an interface in a constructor in MySql EF code ..
It works and does the job but it also displays this error.
