use this type to replace the above Code . When the service starts running, the initializeservice method is automatically executed. You can add code for the entity model entity published by the Service and the read permission of the specified client to the initializeservice method. For example, you can indicate that data in a group of entities is read-only, and data in another group of entities is writable. The following exercises describe how to use a WCF Data Service template to create and co

If you have already filled in the front n-1 a color, there is f (n-1) case, at this time the first n-1 with a color must be different, so nth only one choice. 2.

The local DNS informs the user of the result and caches the result. 5. the user accesses the website server on the China Netcom line.Intelligent DNS is particularly important: There are several important issues that should be listed separately. Otherwise, you will be surprised when using intelligent DNS. 1. Intelligent DNS determines the user source based on "Local DNS" instead of the user's own IP address.

status, and whether GC optimization is necessary or not. If the analysis result shows that GC takes less than 0.1-0.3 seconds, GC optimization is generally not required. However, if GC takes 1-3 seconds or more than 10 seconds, you need to optimize the system immediately. However, if your application allocates 10 GB of memory and cannot reduce the memory capacity, you cannot perform GC optimization. In this case, you should first consider why such a
