ASP.NET 5, EF 7 and SQLite - SQLite Error 1: 'no such table: Blog' entity-framework entity-framework-core sqlite


I followed the Getting Started on ASP.NET 5 guide about Entity Framework 7 and I replaced MicrosoftSqlServer with Sqlite, the only difference in the code is in Startup.cs:

    .AddDbContext<BloggingContext>(options => options.UseSqlite("Filename=db.db"));

When I run the website and navigate to /Blogs, I get an error:

Microsoft.Data.Sqlite.SqliteException was unhandled by user code

I understand this as if there is no table called 'Blog', but when I open the .db file in DB Browser for SQLite, there actually is a table called 'Blog':

Screenshot from DB Browser for SQLite showing a table called 'Blog'

Does SQLite require other changes in the code, or is this an error in the SQLite connector for Entity Framework?

Accepted Answer

It is very likely the database actually being opened by EF is not the file you are opening in DB Browser. SQLite use the process current working directory, which if launched in IIS or other servers, can be a different folder than your source code directory. (See issues and

To ensure your db file is in the right place, use an absolute path. Example:

public class Startup
    private IApplicationEnvironment _appEnv;

    public Startup(IApplicationEnvironment appEnv)
        _appEnv = appEnv;
    public void ConfigureServices(IServiceCollection services)
                options => { options.UseSqlite($"Data Source={_appEnv.ApplicationBasePath}/data.db"); });

Taken from EF Core documentation...

Run from Visual Studio

To run this sample from Visual Studio, you must set the working directory manually to be the root of the project. Ifyou don't set the working directory, the following Microsoft.Data.Sqlite.SqliteException is thrown: SQLite Error 1: 'no such table: Blogs'.

To set the working directory:

  • In Solution Explorer, right click the project and then select Properties.
  • Select the Debug tab in the left pane.
  • Set Working directory to the project directory.
  • Save the changes.
