Bryce,

This could happen for a variety of reasons so let's try to narrow it down. Edit the product in question and change the template to Bvc2013. Then, after saving your changes, click the "View in Store" button below where you selected the template. Did you receive the same error? If so, immediately check the Audit Log (Options >> Audit Log) in the admin.You should see an entry at or near the top that corresponds to the error that you just received (note that the time stamp is in UTC). Clicking the blue description text will open a window with details about the error. Please post that information here.

This is the error that I was getting...
[A]AddToCartClickedEventHandler cannot be cast to [B]AddToCartClickedEventHandler. Type A originates from 'App_Web_oo21gx5x, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\c5732fd4\4ead170d\App_Web_oo21gx5x.dll'. Type B originates from 'App_Web_lbht34yn, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\c5732fd4\4ead170d\App_Web_lbht34yn.dll'.

I rebuilt the solution and am in the middle of doing a push up to the dev server now to see if this resolves it. Will let you know shortly.

Could be temporary file compile cache issue and nothing to do with BV.

Have to tried stopping IIS

Locate C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\c5732fd4\

Delete the folder.

Revisit the website. So that BV recompiles

Yes. However, in BVC 2015 there is the ability to override templates from inside the theme folder (e.g. /BVModules/Themes/Foundation4 Responsive/Product Templates/Bvc2013/).


All of the out-of-the-box templates have the necessary files. So, either the files are missing and need to be copied from a fresh download of BV Commerce, or this is a folder/template that was incorrectly added.


You do not need to rebuild the solution unless you are modified files outside the website project. The website project is compiled automatically by the server the first time it runs.


Has this template ever worked properly? Have you tried to run the site on a local machine or development server? Lastly, are you able to compile the website project without any errors?


I agree; it does sound like a temporary file compile issue. However, I would think that everything you tried should have fixed it. If you're running BVC 2015 try setting the optimizeCompilations attribute to "false" in the <compilation> node of your Web.config file. If that fixes it you can then switch it back.

Ok. So I went and added a comment specifically to the SingleProduct.ascx page and that must have forced a recompile and it now works.
