[Could not load file or assembly ...] in the .NET custom connector (BCS) RRS feed

  • Question

  • Hi,

    I have implemented the .NET Custom connector on BCS. I have to add two assembly files (dll) in order to call custom functionality.

    In the visual studio 2010, I added these two dll via the package designer of BCS (And these assembly was added in the package manifest). Then, I can  deploy this connector to sharepoint farm without any error. And I go to central administrator and deploy this solution without any problem too.

    But, when I start FAST crawl this line of business (BCS), the following error occurs.

    Could not load file or assembly ... or one of its dependencies...

    I also register these two dll in the application server through the VS command prompt by using gacutil.

    I don't know why this error still occurs.

    Do I need to do extra step to add these dll in my .NET custom connector.


    Any help will be much appreciated.

  • Hi Andy,


    Thanks for your post.  Would it be an option for you to copy the complete error message so we can see it?  An example of a complete message is below:

    "Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."

  • Hi Rob,


    Thanks, I think I found the root cause. It is because I am using the Microsoft.Web.Service2.dll but I didn't install the WSE (Web service Enhancement). After I install the WSE, this error was gone.


    Anyway, because I am using the WSE, there is a limit of uploading and downloading file. If I implemented the web or application. I can put this config in the web.config or app.config file to increase the limit







    But, I cannot find .config for the BCS .NET custom connector. I even added the config for that but it didnot work which stated that the "configuration error".


    Do you have any idea where is the .config for the BCS so that I can put the <maxRequestLength> in it?

    Best Regards,
