Question

Im working developing a system web page and suddenly appears this error:

Could not load file or assembly \'System.Web.WebPages.Deployment, Version=1.0.0.0, C         


        

Answer 1

Try copy paste or package install of System.Web.WebPages.dll in your web bin directory.

You can grab it from NuGet Gallery,

https://www.nuget.org/packages/Microsoft.AspNet.WebPages/

See to that the version matches.
