Framework 4.0 Problem at .net Connector 3.0

[former_member212713]

Hi Experts;

I'm trying .net Connector 3.0v on Vs.net 2010 and framework 4.0 platforms.

But I'm taking the following errors.

Isn't .net Connector 3.0 working on the framework 4.0v ?

Do It want to framework 2.0?

Thanks for your interest.

Melih, verify the next things:

1) Did you download the right Connector Assembly? (Connector 3.0 for Framework 4)

2) Is the Project Properties -> Application -> Target Framework pointing to .NET FrameWork 4?

3) May be, it is necessary to include the next in the app.config or web.config:

<?xml version="1.0"?>

<configuration>

<startup useLegacyV2RuntimeActivationPolicy="true">

<supportedRuntime version="v4.0"/>

</startup>

</configuration>

Regards.

Hello Mr. Eduardo Gironas.,

     I Am Also Having The Same Problem. Your Solution Of Adding XML Tags With Values To APP.Config File Is Solved My Problem. Thanks.

Did you manage to solve the issue, I am also getting the same now, can you please help in this.

Can someone please update this thread if they found the solution? I am facing the same issue. The code runs fine on my local dev machine, but the server throws the exception mentioned.

I have the same issue, but I solve it using the following method. I hope it is good for you.

.NET Framework 4 不能自动使用自己的公共语言运行时版本来运行由 .NET Framework 早期版本生成的应用程序。 若要使用 .NET Framework 4 运行较早的应用程序，则必须使用 Visual Studio 中项目的属性指定的目标 .NET Framework 版本编译应用程序, 或使用应用程序配置文件中的 <supportedRuntime> 元素 可指定所支持的运行时。

解决方案，就是在app.config中添加一个配置节：startup

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v2.0.50727"/>
    <supportedRuntime version="v4.0"/>
  </startup>
</configuration>
