ADO. NET is the generic name for class libraries used to operate databases in the. NET Framework SDK. It provides some core objects for database operations. These core objects have been roughly quoted in the previous blog. This blog mainly describes the main objects.1. connection object
The connection object is a datab
difference between the Transient service and the Scoped service is that the Transient service does not go to the cache field to check whether there is any cache before instantiation. If necessary, ServiceProvider will instantiate one for you. All services created by ServiceProvider (either Transient or Scoped) will be released only when ServiceProvider is released. This will cause a problem: If a ServiceProvider does not Dispose for a long time, if it wants to parse a Transient service, it will

Surging uses high-performance RPC remote service calling. If json.net is used for serialization, the performance will not reach the optimal level. Therefore, protobuf and messagepack serialization components are extended to support RPC binary transmission.

This article mainly describes how the. NET Core uses the Redis publishing subscription, the small part feels quite good, now shares to everybody, also gives everybody to make a reference. Let's take a look at it with a little knitting.
Redis is a very powerful memory database that is typically used as a cache, but not just as a cache, such as the well-known dist
