NHibernate 3.3和SysCache [英] NHibernate 3.3 and SysCache

问题描述

当前版本的SysCache似乎不适用于NHibernate 3.3.我替换了web/bin目录中的NHibernate dll，并保持SysCache dll(与3.2兼容)不变.现在，当IIS尝试进行预绑定时，它将加载SysCache dll并尝试将其绑定到NHibernate 3.2.0.4000，然后失败.

The current version of SysCache does not appear to work with NHibernate 3.3. I replaced the NHibernate dlls in my web/bin directory and left the SysCache dll (which works with 3.2) untouched. Now when IIS tries to do a pre-bind it loads the SysCache dll and tries to bind it to NHibernate 3.2.0.4000 and fails.

如果我注释掉web.config中的配置，一切都很好:

If I comment out the configuration in the web.config all is well:

<property name="cache.use_second_level_cache">true</property>
<property name="cache.use_query_cache" >true</property>
<property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property>

位于 NHibernate Contrib 的NHibernate缓存下载站点没有最新版本的下载.

The download site for NHibernate caches at NHibernate Contrib does not have a download for the latest version.

推荐答案

问题可能是SysCache Dll是使用NHibernate 3.2.0构建的，并且与NHibernate 3.3.0不兼容.解决此问题的一种简单方法是仅从 https://nhcontrib.svn.sourceforge.net/svnroot/nhcontrib/trunk/src/NHibernate.Caches 更新NHibernate参考以使用您正在使用的版本，然后重建并使用最新的缓存dll.由于是次要升级，因此无需进行任何代码更改，您就应该安全.

The issue probably is that the SysCache Dll is built using NHibernate 3.2.0 and it is not compatible with NHibernate 3.3.0. An easy way around this is to checkout the trunk of the nhibernate config project or the Cache solution only from https://nhcontrib.svn.sourceforge.net/svnroot/nhcontrib/trunk/src/NHibernate.Caches update the NHibernate reference to use the version that you are using and then rebuild and use the latest cache dlls. Since its a minor upgrade there shouldnt be any code changes required and you should be safe.

尝试一下，让我知道它的进展.

Try it and let me know how it goes.
