Question
How to suppress ambient transaction warning with EF7 RC2?
The SuppressAmbientTransactionWarning() method cannot be found.
Accepted Answer
You can disable that in the DbContext(in old versions):
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer(@"Server=.\;Database=EFTutorial;Trusted_Connection=True;").SuppressAmbientTransactionWarning();
base.OnConfiguring(optionsBuilder);
}
or
If you have the connection string in the json:
var optionsBuilder = new DbContextOptionsBuilder();
optionsBuilder.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]).SuppressAmbientTransactionWarning();
In the new version:
var optionsBuilder = new Microsoft.EntityFrameworkCore.DbContextOptionsBuilder();
var extension = new SqlServerOptionsExtension(optionsBuilder.Options.GetExtension<SqlServerOptionsExtension>())
{
ThrowOnAmbientTransaction = false
};
((IDbContextOptionsBuilderInfrastructure)optionsBuilder).AddOrUpdateExtension(extension);

While the question was related to RC2, as of Oct 16, 2016, this worked for me and hopefully it is useful to someone else:
services.AddDbContext<OpenDataContext>(options =>
{
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
options.ConfigureWarnings(x => x.Ignore(RelationalEventId.AmbientTransactionWarning));
});
Used above in an integration test setup class.
