Problem Solved! :P
-Change your .NET Framework of your program to 4 .
Then
You gotta change your App.config like that ;
="1.0"
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
</configuration>
to
="1.0"
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
</configuration>
(If still does not work you can try to change your Platform Target "Properties > Build > Platform Target" to 64x or 86x(The same as your Refences) .)
It worked for me!
