Could not load file or assembly 'System.Web.Providers"

Question

hello this my config file

Answer 1

For me, I had upgraded the version of Web Providers with NuGet and this broke my app. I had to go into web.config and manually update all assembly references in the provider sections to 2.0.0.0 instead of 1.0.0.0 since the new version of the System.Web.Providers assembly was 2.0.0.0.
