Hi Pavel, I was playing around with different options and once I specified [Serializable] annotation at the entity class level, I was able to successfully insert into cache. With this setting LoadCache() method is working as well. Not sure if this is the right approach. I will not prefer this as this needs an update to a auto-generated class and any subsequent updates might overide the manual settings.
On a separate note, is there a way I can query the cache using sql console. In java, I can set IGNITE_H2_DEBUG_CONSOLE to query the cache. Wondering if there is an equivalent on .NET side. Thanks, Satya. On Mon, Apr 4, 2016 at 8:08 PM, Murthy Kakarlamudi <[email protected]> wrote: > Hi Pavel, > I am not able to send the solution zip in gmail.
