I am trying to configure Firebird with EF6 as an embedded server for a simple application that I am writing but could not get it to work. I have a CLI project, which is an application and a DAL project, which is a database. I added NuGet packages to both and created a DbContext with a simple entity and successfully created the initial migration, but when I tried update-databaseto execute the migration, I received this error in the package manager console:
System.Runtime.Serialization.SerializationException: Type is not resolved for member 'FirebirdSql.Data.FirebirdClient.FbException,FirebirdSql.Data.FirebirdClient, Version=4.10.0.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c'.

In fact, I just noticed that nothing is working now ... If I delete my migration and try to recreate it, I get this error. I managed to enable migrations and create them earlier, but now I can’t. Bizarre
All of my projects are targeting .NET 4.5.2, and they all have the same package versions. There are no spaces or ampersands or strange characters in my solution / project path. I tried using my application project as a launch project and a DAL project, and this did not help.
My packages.config:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="EntityFramework" version="6.1.3" targetFramework="net452" />

The connection string I just found on the network, so this might be wrong, but I did not find any documentation for it ...
I have already done the EF code dozens of times with SqlServer before and have never encountered this problem before, but this application will not have a real server. Unfortunately, this seems like a more general problem than Firebird or EF, but I'm not sure where to even look at this point.
