Error every time on first load of /umbraco/umbraco.aspx - Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute'

bugs

Using Umbraco v6.2.1 (Assembly version: 1.0.5261.28997)

I have local/dev/qa/prod environments. Everytime I go to access the UI on dev/qa/prod after an hour or two, I will see this error (below). If I reload the page it goes away. I have told the end-users to just ignore it and reload the page, but it is annoying and I would like to figure out how to fix and not see the error at all. It doesn't happen on my localhost, which is where the project is compiled and then pushed to dev/qa/prod. Target framework is set at .net 4.0, because that is what the servers have. This started happeneing after I installed Contour.

Please help, thank you.

Hi Karen,

I have tried to search on the error that you get, Did you use Contour version 3.0.21, if you do you could try go to the bin folder of your Umbraco installation and see if you can find a dll with the name Umbraco.Forms.Core.Providers.V7.dll

Since you have an local/dev/qa/prod environments setup, I would try do remove the file (if you can find it in the bin folder) from your local environment first, to ensure that your Umbraco backoffice still works after you have removed it, then you also can check that the website still works on frontend too.

Hope this helps,

/Dennis
