C# Execute 2 Threads Simultaneously?

I am trying to reproduce a threading error condition within an HTTP Handler.

Basically, the ASP.net worker procecss is creating 2 threads which invoke the HTTP handler in my application simultaneously when a certain page loads.

Inside the http handler, is a resource which is not thread safe. Hence, when the 2 threads try to access it simultaneously an exception occurs.

I could potentially, put a lock statement around the resource, however I want to make sure that it is infact the case. So I wanted to create the situation in a console application first.

But i cant get 2 threads to execute a method at the same time like asp.net wp does. So, my question is how can you can create 2 threads which can execute a method at the same time.

Edit:

The underlying resource is a sql database with a user table (has a name column only). Here is a sample code i tried.

[TestClass]
public class UnitTest1
{
[TestMethod]
public void Linq2SqlThreadSafetyTest()

[Code]....
