Unit test with entity framework DB context: Does not reset ID counter

I'm trying to write unit test of a fairly simple webservice based on ASP.Net core. For persistence I use entity framework core to access a SQL databse.

In the unit tests I obviously don't want a database that could bleed from one test into another. After some searching I found this article https://docs.microsoft.com/en-us/ef/core/miscellaneous/testing/in-memory. My test code looks now something like this:

[Fact]
public void Test_method()
{    
    var options = new DbContextOptionsBuilder<ServiceContext>()
        .UseInMemoryDatabase(databaseName: "Test_method") // Unique name for each test
        .Options;

    using (var context = new ServiceContext(options))
    {
        // Add test data
        context.Dataset.Add(new ...);
        context.SaveChanges();
    }

    using (var context = new ServiceContext(options))
    {
        // Perform tests
        var controller = new Controller(new Service(context));
        ...
    }
}

That almost works, each test case starts out with an empty DB. But the IDs the testdata elements get assigned does not reset. So if I have one test that adds one element to its DB and another test that adds two, the test element in the first test might get ID 1 or 3, depending on the order in which those two tests are executed.

Is there a way to make sure IDs always start with 1 within a single test method? Testing code that does ID based lookup is really quite ugly when the IDs depend on whether or not other tests ran before the current one.
