C # using GRPC issues Rollup

Grpc is a cross-platform remote call framework, for the first time in the Windows platform, there are a lot of problems to face, a summary of the following to prepare for inspection

Problem with message length setting 1

Workaround

This problem occurs when GRPC limits the default message size (massage size), the value of the limit is not quite the same in each version, in order to make the GRPC more efficient, the developer thinks should not be too big, 4M more appropriate.

But in practical application, although it can be stipulated that writing contract is reasonable, but there will be many large objects.

The workaround is to manually set the value of the messagesize.

Issue 1 is that the client cannot resolve after the client has set messagesize and received a large object. Issue 2 is that messagesize is not set on the server side and the server cannot resolve the message sent.

Code required on the service side

 Varoptions = new list< channeloption> {new  (channeloptions. Maxmessagelength,int. Maxvalue) }; channel channel = new Channel< Span class= "P" > ( "127.0.0.1:50051" channelcredentials insecureoptions);       

Code required on the client

ServerServer=NewServer(NewList<Channeloption>{NewChanneloption(Channeloptions.maxmessagelengthint. Maxvalue) }) {services = {greeter. Bindservice (new greeterimpl ())  }, ports = {new serverport ( "localhost" port Servercredentials. Insecure) } };   

In the end this value is set to how much reasonable if set to int. MaxValue, what impact on performance, in the later use gradually realized.
