Cs0009 Demystified: Correcting Unreadable Metadata Errors
Introduction
Cs0009 is a common error message that can occur when working with Microsoft SharePoint. The error reads:
Cs0009: Could not load file or assembly ‘Microsoft.SharePoint.Library, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)**
This error message can be caused by a variety of factors, including:
- Corrupted or missing SharePoint metadata
- Incorrectly configured SharePoint settings
- Incompatible versions of SharePoint
Resolving the Cs0009 Error
There are a number of steps that can be taken to resolve the Cs0009 error:
- Check the SharePoint metadata. The first step is to check the SharePoint metadata to ensure that it is not corrupted or missing. This can be done by using the SharePoint Central Administration tool.
- Check the SharePoint settings. The next step is to check the SharePoint settings to ensure that they are configured correctly. This includes checking the following settings:
- The SharePoint web application settings
- The SharePoint farm settings
- The SharePoint security settings
- Update the SharePoint version. If the SharePoint version is out of date, it may be necessary to update it to the latest version. This can be done by using the SharePoint Central Administration tool.
- Reinstall SharePoint. If all else fails, it may be necessary to reinstall SharePoint. This should be done by a qualified IT professional.
Additional Troubleshooting Tips
In addition to the steps outlined above, there are a few other troubleshooting tips that can be helpful:
- Use a different browser. If you are experiencing the Cs0009 error when using a particular browser, try using a different browser.
- Clear the browser cache. Clearing the browser cache can sometimes resolve the Cs0009 error.
- Disable browser extensions. Some browser extensions can interfere with SharePoint. Try disabling all browser extensions and then see if the Cs0009 error still occurs.
This is a great tutorial! I was having trouble with unreadable metadata errors, but this fixed it right away. Thanks!
I’m not sure why this is happening. I’ve never had this problem before.
There is another way to fix this issue. You can use a hex editor to repair the corrupted file.
This is a dumb solution. Why can’t Microsoft just fix this bug?
I know, right? This is like, the most basic thing. You’d think they would have fixed it by now.
Oh, yeah, that’s a great idea. Let me just go grab my hex editor and fix this myself. Thanks for the help, Microsoft.
Hey, did you know that you can also use a metadata repair tool to fix this issue?
