SQLServer Persistence Store Error

[Murthy Kakarlamudi]

Hi,
   In my .NET application, I have an underlying SQL Server DB that I am
planning to access using Ignite Persistence feature. I was following the
StoreExample provided in the examples and created the ignite configuration
accordingly.

<property name="cacheConfiguration">
        <list>
          <bean class="org.apache.ignite.configuration.CacheConfiguration">
            <property name="writeThrough" value="true"/>
            <property name="readThrough" value="true"/>
            <property name="cacheStoreFactory">
              <bean
class="org.apache.ignite.platform.dotnet.PlatformDotNetCacheStoreFactory">
                <property name="typeName" value="MyIgnite.SQLServerStore,
MyIgnite"/>
              </bean>
            </property>
          </bean>
        </list>
      </property>

My SQLServerStore which is part of MyIgnite dll is as below. I am using
EntityFramework as ORM to access underlying SQLServer.

class SQLServerStore : CacheStoreAdapter
    {
        private TestEntities entities;
        public SQLServerStore()
        {
            entities = new TestEntities();
        }

        /// <summary>
        /// Loads all values from underlying persistent storage.
        /// This method gets called as a result of <see
cref="ICache{TK,TV}.LoadCache"/> call.
        /// </summary>
        /// <param name="act">Action that loads a cache entry.</param>
        /// <param name="args">Optional arguments.</param>
        public override void LoadCache(Action<object, object> act, params
object[] args)
        {
            var personDetailsList = entities.PersonDetails;
            // Iterate over whole underlying store and call act on each
entry to load it into the cache.
            foreach (personDetail entry in personDetailsList)
            {
                act(entry.personD, entry);
            }

        }
}

Whwn I try to run the above, I am getting the below error.

Any help would be appreciated.
