Trying to run EF Code first Migrate.exe tool on production environment failed - entity-framework

Question

I'm using EntityFramework version 6.1.3.
I copied migrate.exe from EntityFramework version 6.1.3 package tool folder to bin folder of my website.
My web site is compiled and published to production environment with x86 CPU and target framework 4.5.1
I run the following command:
D:\Sites\MatrixPortal\bin>migrate.exe
d:\sites\MatrixPortal\bin\MatrixPortal.BL.dll
/startUpDirectory="d:\Sites\MatrixPortal\bin"
/startUpConfigurationFile="d:\Sites\MatrixPortal\Web.config"
and i get the following error:
ERROR: Could not load file or assembly
'd:\sites\MatrixPortal\bin\MatrixPortal.BL' or one of its
dependencies. The given assembly name or codebase was invalid.
(Exception from HRESULT: 0x80131047)
EDIT:
when i try this:
migrate MatrixPortal.BL.dll /verbose
i get other error:
System.BadImageFormatException: Could not load file or assembly
'MatrixPortal.BL' or one of its dependencies. An attempt was made to
load a program with an incorrect format. File name: 'MatrixPortal.BL'

also tried this:
http://www.azurefromthetrenches.com/command-line-entity-framework-code-first-migrations/
and created a file called Redirect.config with the following content:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>

<bindingRedirect oldVersion="0.0.0-6.1.3" newVersion="6.1.3" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
but got the same error as above :(

Answer 1

In my case I got the error because I wrote migrate .\MyAssembly.dll instead of migrate MyAssembly.dll.
See Common Problems documentation section.

Answer 2

SOLVED!
I've Published the web site project with x86 target cpu, and apparently it wasn't really x86, i don't know why, maybe a bug?
After changing Publish to any cpu it worked. i was able to run migrate.exe without an error using the following arguments:
migrate.exe MatrixPortal.BL.dll /verbose /startUpDataDirectory="D:\Sites\MatrixPortal" /startUpConfigurationFile="D:\Sites\MatrixPortal\Web.config"
