An object reference is required for the non-static field, method, or property 'MetaData.Current'

After updating a v7 site from v2.2.1 -> 2.2.5 I get this error - I'm sure it's something obvious but I'm drawing a blank!

Hi Steve,

Do you have a call stack?

Best,

Richard

It comes from the view, how do you call the SEOChecker property?

Hi,

In the master template whomever has set this up has just used

@using SEOChecker.Library

Then uses the static to output keywords etc... @MetaData.Current.Keywords

When I update the nuget package this stops working. Can't see anything that's changed other than the SEOChecker code?

What would be the recommended way to get the keywords etc?

That should have gone wrong in the previous version as well.

Syntax is

@{
 var seo = Model.Value("your seochecker property alias") as SEOChecker.MVC.MetaData;
   }

 @seo.AllTags

Hope this helps,

Richard

Hi,

Weird - I wonder if the dev has buried some static that I can't find that does this on start up... never mind - thanks for the response.
