NET2.0 Environment Development (the latest version is 1.0.66.0, released on April 18, 2010), and the current official has not given the latest. NET4 data access support.

Workaround:

Add a configuration item to the configuration file <supportedruntime version= "v2.0.50727"/>

As shown below:

<?xml version= "1.0" encoding= "Utf-8"?>
<configuration>

<startup uselegacyv2runtimeactivationpolicy= "true" >

<supportedruntime version= "v4.0" sku= ". netframework,version=v4.0 "/>

<supportedruntime version= "v2.0.50727"/>

</startup>

</configuration>
