Question: I tried to solve this with logarithm rules:

O(n^2) = 2^O(log(n^2)) 

c\*n^2 = 2^log(n^2c)

Im not sure that is true?

Answer: 
I solved this error changing the initial project to the Entity Project. 

Look:

Update-Database -Verbose
**Using StartUp project 'SCVE.Web'.** <-- this ir error
Using NuGet project 'SCVE.EntityFramework'.
If you are trying to connect to Sql Server instead of localdb then make sure the default connection factory in web.config file is as below:

```
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
  <parameters>
    <parameter value="Data Source=.\SQLEXPRESS2012; Integrated Security=True; MultipleActiveResultSets=True" />
  </parameters>
 </defaultConnectionFactory>

```
