Taxonomy Picker issue

Symptoms:

Load control template file /_controltemplates/TaxonomyPicker.ascx failed: Could not load type ‘Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker’ from assembly ‘Microsoft.SharePoint.Portal, Version=14.0.0.0

Diagnosis:

Config file issue… no way…

Solution:

Thanks to Xiaofeng Wang MVP

<Update: If you keep on getting this error in your log, just rename the file TaxonomyPucker.ascx to TaxonomyPucker.ascx_deprecated so that SharePoint does not try to recompile each time the AppPool restarts, this control is never used by SharePoint so no harm in taking it out of scope>

I still have the same issue in RC. Even though there is no error when you peform various operations on the site UI, but you may find this error in the system Event Log. Here is my resolustion:

Go to <drive>:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES,

Open TaxonomyPicker.ascx in any text editor,

Locate the following line :

<%@ Control className="TaxonomyPickerControl" Language="C#" Inherits="Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker,Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

> Replace ‘,‘ with ‘,‘ , the correct line should look like

<%@ Control className="TaxonomyPickerControl" Language="C#" Inherits="Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker, Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Worked for me..
