`Method 'DoExecuteBatch' does not have an implementation.

[phucphanJaneto]

After I upgrade Nhibernate to version 5.0.0 and NHibernate.Caches.SysCache2, I get the error message

Method 'DoExecuteBatch' in type 'NHibernate.MySQLBatcher.MySqlClientBatchingBatcher' from assembly 'NHibernate.MySQLBatcher, Version=1.0.3.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

This is my code for this:
var configure = new Configuration().Configure(); configure.DataBaseIntegration(x => { x.Dialect<MySQL5Dialect>(); x.ConnectionStringName = "db"; x.BatchSize = 20; x.Batcher<MySqlClientBatchingBatcherFactory>(); }) .Cache(x => x.UseQueryCache = true) .CurrentSessionContext<WebSessionContext>();

How can I fix this?

It looks like the signature of the DoExecuteBatch method has changed between NHibernate 3.x (which this library targets) and NHibernate 5. The existing method takes an IDbCommand while the new method takes DbCommand. You may be able to change the signature and recompile, but I'm not sure if that will work or not.

Unfortunately, I haven't touched NHibernate or this library in over five years!
