Using MySql

As a client admin interface I use mysql-workbench.

Obviously you need to have MariaDb or MySql installed.

Create MariaDb (MySql) user and DB

Create a database for DatingApp (do not use password as a password)

sudo su - root
CREATE USER 'datingappuser'@'localhost' IDENTIFIED BY 'password';
CREATE DATABASE `datingappdb`;
# Grant the user the privilege to access mariadb without any other privilege
GRANT USAGE ON *.* TO 'datingappuser'@localhost IDENTIFIED BY 'password';
# Grant the user all privileges on the application db
GRANT ALL PRIVILEGES ON `datingappdb`.* TO 'datingappuser'@'localhost' WITH GRANT OPTION;
SHOW GRANTS FOR 'datingappuser'@localhost;

EF DB provider

On the page of the provider nuget package verify the version. At the time of writing it was 2.1.1, so we need to update (or downgrade) dotnet core to SDK 2.1.301. Unfortunately there is no way to do that with the package manager.

sudo apt-get install dotnet-sdk-2.1

It installed 2.1.302 and ef version is 2.1.1-rtm-30846 so I hope the provider will work.

Open DatingApp.API.csproj and update the reference version for EF Sqlite

<PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="2.1.1"/>


dotnet restore

Now install the provider for MySql

dotnet add package Pomelo.EntityFrameworkCore.MySql --version 2.1.1
dotnet restore

Open Startup.cs and duplicate the method ConfigureServices and name the copy as ConfigureDevelopmentServices. Those two methods will be called by convention based on the environment.

Now we can change ConfigureServices to use MySql and still mantain Sqlite for development

services.AddDbContext<DatingContext>(options => options.UseMySql(Configuration.GetConnectionString("DatingDbConnection")));

Move the connection string for Sqlite from appsettings.json to appsettings.Development.json

  "ConnectionStrings": {
    "DatingDbConnection": "Data Source=DatingApp.db;"
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "System": "Information",
      "Microsoft": "Information"

In appsettings.json change the connection string to MySql

"DatingDbConnection": "Server=localhost; Database=datingappdb; Uid=datingappuser; Pwd=password;"

There is some convoluted way to keep the migrations for both databases. To keep things simple I just moved the Migrations folder out of the solution. Now when we create a new migration ef will start from zero.

dotnet ef migrations add Initial
dotnet ef database update
