<para>The <see cref="T:System.Data.IsolationLevel" /> values are used by a .NET Framework data provider when performing a transaction.</para>
<para>The <see cref="T:System.Data.IsolationLevel" /> remains in effect until explicitly changed, but it can be changed at any time. The new value is used at execution time, not parse time. If changed during a transaction, the expected behavior of the server is to apply the new locking level to all statements remaining.</para>
