Razor intellisense error: Feature 'extension method' cannot be used because it is not part of the ISO-2 C# language specification

Question

Goal:

• Use cshtml Razor templates to format data
• Embed cshtml Razor templates in Class Library as Embedded Resources

Answer 1

The solution for me was to change the project type

1.Unload the project

2.Edit project

3.Add line below (depending on your project MVC version) right after ProjectGuid

MVC 4

{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}

MVC 3

{E53F8FEA-EAE0-44A6-8774-FFD645390401};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}

Try adding this to the Web.Config in the Root of the project (not in the Views Folder)
