I have made some research about how to install Commerce into my CMS, i am not talking about CommerceManager.
There is a nuget (https://nuget.episerver.com/en/OtherPages/Package/?packageId=EPiServer.Commerce) and install it, but i got some error afterwards.
Is the nuget only support Webforms?
I have the latest CMS nuget installed in my solution, and off cource its MVC. But after i installed the nuget aboved, I got error about "RoutePrefix"...
I maybe installing Commerce the wrong way?
There is a couple of packages you need to install, you can find detailed step-by-step instructions here:
EPiServer Commerce fully supports MVC.
As Mari pointed out, EPiServer Commerce fully supports both WebForms and MVC. Without any detail of the error you get it's very hard to know what is wrong.
