Web Congif Dosyasının görüntüsü şöyle olmalıdır.

<connectionStrings>
  <!-- For Identtiy   -->
  <add name="ExpenditureIdentity"

For a local SQL Server:

• Open SQL Server Management Studio (SSMS) and connect to the SQL Server.
• Open the Security folder at the server level and not the security folder for the database.
• Right click on the logins and select New Login.
• For the login, type IIS APPPOOL\AppPoolName and DO NOT CLICK SEARCH and select OK (If a search is executed, it will resolve to an account with ServerName\AppPool Name and SQL will be unable to resolve the account’s SID since it is virtual)
• User MappingPage>Select Database > Set User IIS APPPOOL\AppPoolName; setDefault Schema> dbOwner
• Select the defaults for the account and select OK to close dialog

The same can be accomplished using T-SQL:
CREATE LOGIN [IIS APPPOOL\AuthTest] FROM WINDOWS;
CREATE USER AuthTest FOR LOGIN [IIS APPPOOL\AuthTest];
For a remote SQL Server:

• Open SQL Server Management Studio (SSMS) and connect to the SQL Server.
• Open the Security folder at the server level and not the security folder for the database.
• Right click on the logins and select New Login.
• For the login, type Domain\ServerName$ and DO NOT CLICK SEARCH
• Select OK
• Select the defaults for the account and select OK to close dialog

System.InvalidOperationException

System.InvalidOperationException: 'No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file.

Solution:
You've added EF to a class library project. You also need to add it to the project that references it (your console app, website or whatever).
