更新数据库期间用户登录失败

Question

I have a big problem. I tried to use another solution but didn't help me. I try to make initial migration (code-first workflow) to database which is on my computer. I used commands in PM like enable-migrations, then add-migration NameMigration , then update-database and at this moment I have an error like:

Error Number:4060,State:1,Class:11
Cannot open database "CodeFirstDemo.Program+BlogDbContext" requested by the login. The login failed.
Login failed for user 'SZYMON\Szymon'.

My config:

<entityFramework>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="mssqllocaldb" />
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>
  <connectionStrings>
    <add name="BlogDbContext" connectionString="Data Source=SZYMON\BASE; Initial Catalog=CodeFirstDemo; Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
  </connectionStrings>

Database is not exist yet. My object explorer in MS SQL Server looks enter image description here

Server properties looks enter image description here

I don't know what is wrong. Please help me to solve problem.

Answer 1

It does not seem that you have access to the database server. Try to login using SQL Management Studio to SZYMON\BASE db server using windows authentication.
