FileBaseContext

FileBaseContext is a provider of Entity Framework Core 8 to store database information in files.

It was built for development purposes. All information is stored in files that can be added, updated, or deleted manually.

Benefits

  • you don't need a database
  • rapid modeling
  • version control supported
  • supports all serializable .NET types-
  • unit tests

Configure Database Context

add database context to services

services.AddDbContext<ApplicationDbContext>(options => options.UseFileBaseContextDatabase("dbUser"));

or configure the database context itself

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
	optionsBuilder.UseFileStoreDatabase("my_local_db");
	base.OnConfiguring(optionsBuilder);
}

Configure Provider

Named database
optionsBuilder.UseFileBaseContextDatabase(databaseName: "my_local_db");
Custom location
optionsBuilder.UseFileBaseContextDatabase(location: "C:\Temp\userDb");

Unit testing

Since 2.1.0 the FileBaseContext injects access to the file system through System.IO.Abstractions library. It allows the use of the provider in unit tests.

If you need to use the provider in unit tests, you can change IFileSystem to MockFileSystem in OnConfiguring method in datacontext class.

private readonly MockFileSystem _fileSystem;
public DbTestContext(MockFileSystem fileSystem)
{
    _fileSystem = fileSystem;
}

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.UseFileBaseContextDatabase(DatabaseName, null, services =>
    {
        services.AddMockFileSystem(_fileSystem);
    });
}

Please find example in the SimplePositiveTests class in the test project
