C# 使用SQLite由于.NetFramework 的错误

In order to use a CLR 2.0 mixed
mode assembly, you need to modify your App.Config file to include:

<?xml version="1.0"?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>

The key is the

useLegacyV2RuntimeActivationPolicy

flag.
This causes the CLR to use the latest version (4.0) to load your mixed mode assembly. Without this, it will not work.

Note that this only matters for mixed mode (C++/CLI) assemblies. You can load all managed CLR 2 assemblies without specifying this in

app.config

.
