| /// <example> |
| /// You can use cache transactions as follows: |
| /// <code> |
| /// using (var tx = igniteClient.GetTransactions().TxStart()) |
| /// { |
| /// int v1 = cache<string, int>.Get("k1"); |
| /// |
| /// // Check if v1 satisfies some condition before doing a put. |
| /// if (v1 > 0) |
| /// cache.Put<string, int>("k1", 2); |
| /// |
| /// cache.Remove("k2"); |
| /// |
| /// // Commit the transaction. |
| /// tx.Commit(); |
| /// } |
| /// </code> |
| /// </example> |
| /// |
| /// Alternatively, <see cref="TransactionScope"/> can be used to start Ignite transactions. |
| /// <example> |
| /// <code> |
| /// using (var ts = new TransactionScope()) |

| /// int v1 = cache<string, int>.Get("k1"); |
