【问题描述】：
我正在使用标准 fluent nhibernate 下载中的所有 dll，以及标准 sqlite dll。
它只有在我将目标框架切换到 3.5 时才有效——在这种情况下，system.data 的引用切换到版本 2。——所以这个 dll 可能是原因。
我很惊讶流畅的 nhibernate 似乎不能立即工作。
如果有人能告诉我如何让 .net 4 控制台应用程序使用 .net 3.5 system.data dll（版本 2.），那可能会解决它。或者，如果某个地方有一个秘密的流利的 nhibernate 下载可以工作......
编辑：好的，这里有一些错误信息.......
编辑：已解决！使用此 app.config 文件：
<?xml version="1.0"?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true"><supportedRuntime version="v4.0"/>
</startup>
</configuration>

【问题讨论】：
-
您应该发布您看到的错误并确保您没有。 NET 4.0 客户端配置文件已选择。
-
"System.IO.FileLoadException: 混合模式程序集是针对运行时版本 'v2.0.50727' 构建的，如果没有其他配置信息，则无法在 4.0 运行时中加载。"似乎是你的问题。 stackoverflow.com/questions/2455654/… 是一个可能的解决方案。
-
好的，谢谢，我用这个 app.config 文件修复了它：
-
确实，我想我可能会错过 SQLite，直到它更新为 4.0。我一直在使用 SQLCE 进行测试，它似乎工作得很好。
-
我仍然不知道 sqlite 是问题所在。我尝试了这个版本，即 .net 4.0：system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki ...它仍然无法正常工作（没有 ap.config 更改）。另一方面，nhibernate 和 fluent nhibernate dll 是针对 .net 2.0 构建的。
