Answer 1

Just wanted to leave a comment here in case anybody wandered by this post while researching this issue. I ran into this randomly on .net core 2.1 using Dapper, which includes System.Data.SqlClient 4.5.0 by default. Adding version System.Data.SqlClient 4.5.1 independently via nuget worked. So it seems this has been fixed as of 4.5.1.

The following are the relevant sections of my csproj file:

<ItemGroup>
   <PackageReference Include="Dapper" Version="1.50.5" />
   <PackageReference Include="System.Data.SqlClient" Version="4.5.1" />
</ItemGroup>

Update 2 .NET Core 2.0 is out now. You can use this API. See https://docs.microsoft.com/en-us/dotnet/api/system.transactions.transactionscope?view=netcore-2.0

Update System.Transactions will be available in NET Core 2.0. See https://github.com/dotnet/core/blob/master/roadmap.md for details on upcoming releases.

Original answer

System.Transactions (or ambient transactions) is not implemented in .NET Core 1.0.0 but may be implemented in future versions.

You can work around this by using explicit transactions.

        using (var connection = new SqlConnection(connectionString))
        {
            connection.Open();

            using (var transaction = connection.BeginTransaction())
            {
               // transaction.Commit();
               // transaction.Rollback();
            }
        }
