.net - C# Serialization issues while mapping one version of a type to a different version of a type -

-

background
have encountered strange situation in application uses 3rd party component. quite few classes in application implements iserializable interface persist object state , forth. face compatibility issues during course of serialization when serialize app classes in 1 version , try deserialize different version of 3rd party component.

issue
latest release of 3rd party component saw major shuffling w.r.t types , assemblies.

i.e. ex :
earlier type t1 found under assembly a1. . post new release, assembly a1 has been split 2 different assemblies ex: a11 , a12. , type t1 housed in a12

the type t1 on deserialization, trying find assembly a1. since has been moved different assembly a12 throwing serializationexception stating not able find assembly a1.

things tried:

1. serializationbinder:
used serializationbinder class checked incoming assemblyname , typename information , suitably routed correct assembly on deserialization.

2. assemblyresolve event using resolveeventhandler delegate
can extract assembly file name assembly’s identity , can re-route updated path application can find assembly file using call assembly.loadfrom load assembly , return resulting assembly reference resolveeventhandler method

although both of above approach works extent. quite task supply routing information correct assembly types marked serializable in application. not mention has updated again future releases.

so i'm here ask help/suggestions/alternatives

has here has experienced such situation ? how able tackle such issue ? if generous shed best practices , pitfalls avoid when using serialization 3rd party components

cheers , in advance vatsag

about binaryformatter: what deficiencies of built-in binaryformatter based .net serialization?

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
