Migrating to MartinCostello.SqlLocalDb from System.Data.SqlLocalDb

Migrating to MartinCostello.SqlLocalDb from System.Data.SqlLocalDb

This document explains some of the steps required to migrate from System.Data.SqlLocalDb 1.x.x to MartinCostello.SqlLocalDb 2.0.0 and later. It is not exhaustive as use-cases may differ, but illustrates equivalent namespace and type names, as well as equivalents for certain tasks.

• Remove references(s) to the System.Data.SqlLocalDb NuGet package.
• Add reference(s) to the MartinCostello.SqlLocalDb NuGet package.
• Change uses of the System.Data.SqlLocalDb namespace to MartinCostello.SqlLocalDb.
• Change usage of SqlLocalDbApiWrapper for SqlLocalDbApi.
• Remove any application settings used by System.Data.SqlLocalDb to using the SqlLocalDbOptions class in code instead (see Configuration).
• Remove any references to the static SqlLocalDbApi class and use instance-based methods on SqlLocalDbApi/ISqlLocalDbApi and/or ISqlLocalDbInstanceManager/SqlLocalDbInstanceManager instead.
• Change any usage of ISqlLocalDbInstance to ISqlLocalDbInstanceInfo.
• Change any usage of static methods on the TemporarySqlLocalDbInstance class to use the CreateTemporaryInstance() extension method on the ISqlLocalDbApi interface instead.
• For dependency injection in .NET Core applications, you can use the AddSqlLocalDB() method with IServiceCollection to register the ISqlLocalDbApi and SqlLocalDbOptions types.

How-To Guide

Check SQL Server LocalDB is installed

using (var localDB = new SqlLocalDbApi())
{
    if (!localDB.IsLocalDBInstalled())
    {
        // Do something if SQL Server LocalDB is not installed
    }
}

Get available SQL LocalDB instances

using (var localDB = new SqlLocalDbApi())
{
    var instances = localDB.GetInstances();

    foreach (ISqlLocalDbInstanceInfo instanceInfo in instances)
    {
        // Do something with the instances
    }
}

Check whether an SQL LocalDB instance exists

using (var localDB = new SqlLocalDbApi())
{
    if (localDB.InstanceExists("MyInstance"))
    {
        // Do something if the instance exists
    }
}

Create a new SQL LocalDB instance

using (var localDB = new SqlLocalDbApi())
{
    ISqlLocalDbInstanceInfo instance = localDB.CreateInstance("MyInstance");
    // ...
}

Execute a SQL query against an instance

using (var localDB = new SqlLocalDbApi())
{
    var instance = localDB.GetInstanceInfo("MyInstance");

    var manager = new SqlLocalDbInstanceManager(instance, localDB);
    manager.Start();

    using (SqlConnection connection = manager.CreateConnection())
    {
        connection.Open();

        try
        {
            // Do something with the SQL connection
        }
        finally
        {
            connection.Close();
        }
    }
}
