最近在看WCSF, 有些地方有这些前缀的控件<ajaxtoolkitwcsfextensions:

引用的dll是AjaxControlToolkit.WCSFExtensions, 一运行,会出错,错误信息是:

Could not load file or assembly 'AjaxControlToolkit, Version=3.0.11119.25533, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

到网上搜了一下, 解决办法是:

ust Remove the Runat="server" property

<ajaxtoolkitwcsfextensions:ServerSideValidationExtender ID="AccountNumberServerSideValidationExtender"
runat="server" TargetControlID="AccountNumberPropertyProxyValidator">
</ajaxtoolkitwcsfextensions:ServerSideValidationExtender>

remove runat="server" it will work definitely ...
