I am working on a SharePoint site that was restored to a development machine from a test server. Whenever I try to compile and build a new Web Part that I am working on from Visual Studio, I get the following error (in the browser Window):

Line 1:  <%@ Register TagPrefix="WpNs3" Namespace="<ProjectName>.WeatherMap" Assembly="<ProjectName>, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0521399ff9cdd4c1"%>

The ENTIRE error page looks like this:

Server Error in '/' Application.

Assembly Load Trace: The following information can be helpful to determine why the assembly '<ProjectName>, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0521399ff9cdd4c1' could not be loaded.


WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Append the querystring argument "?contents=1" to the page url. Use the options that are displayed to delete the webpart from the page.

That was certainly useful, thanks. It didn't solve the problem (this is the SharePoint install from hell). I did try it, and I rebooted IIS after deleting some of the web parts that were showing as having errors.

So what's the remaining errors?

From looking at the message, your page references features and components that have not been installed on this other server. Just the content database has been moved over?

Attached, you will find a PDF with screenshots of what I am seeing. You say I might not have features activated? That's odd, because the site runs fine BEFORE I run the code in debug mode in Visual Studio. Even the web part in question (known as the WeatherMap) looks fine until I try to debug.

I DID have some features that were not activated, but none of them had to do with the "WeatherMap" Web Part. Following your lead, I activated them all, and the error went away. Now, I'm reloading the site to make sure it works.

Moral of the story: Even if you don't think your Web Part is connected to a feature, it might be.
