Error in webservice after publishing

Question

I created a webservice when it hosted on my local computer it works fine, but when i publish it to the web host, it doesnt work any more, i guess its a question about how the webserver is configured, but can i make some changes in web.config so it will work?

The error i get is below:

Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'MySql.Data, Version=5.0.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' could not be loaded.

The webservice uses ac# class placed in the app_code folder. That c# class uses mysql. When i use the class in a normal .aspx file it works fine

Answer 1

我想很明显的事情是检查服务器上GAC（或Web服务的bin文件夹）中是否存在MySql.Data，并且版本和公钥是否正确？

Answer 2

Basically, you are missing this DLL. You should look at putting it in the bin directory of your webservice.

Answer 3

There could also be a versioning conflict between the MySql client you want and what is installed on the server. You can add the following section to your web.config file and specify the proper version/public key you need:

<compilation debug="false">
   <assemblies>       
      <add assembly="MySql.Data, Version=5.0.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
    </assemblies>
</compilation>
