Solution 1

Right mouse on your website -> Convert to webapplication. See: How To Convert ASP.NET Website to ASP.NET Web Application

Solution 2

If you get this nuget all extention objects are visibles

Install-Package AntiXSS

it solves my problem.

html = Microsoft.Security.Application.Encoder.HtmlEncode(model.SiteName), model = Microsoft.Security.Application.Encoder.HtmlEncode(json),

Solution 3

Uninstall and re-install AntiXSS:

Tools --> NuGet Package Manager --> Package Manager Console (UI may differ if using other than Visual Studio 2013):

Uninstall-Package AntiXSS
Install-Package AntiXSS

For multi-project solutions, be sure to set the default project to whichever one is experiencing the problem. Use Uninstall-Package -Force AntiXSS if uninstall fails and if you can handle any package dependency problems that may arise, though I know of none for this package.

Solution 4

If, like me, you're using AntiXSSLibrary in a class library via Nuget, and got the above error:

  1. Remove all external references that you had through Nuget
  2. Remove the Nuget package file - which is packages.config found in the solution's root directory
  3. Remove the packages directory - again in your solution's root directory
  4. Reinstall all your components again

Solution 5

The answer here helped me. I found the AntiXssLibrary.dll on my site's bin folder.

    I can't include Microsoft.Security.Application

    using Microsoft.Security.Application;
    

    Gives this error:

    The type or namespace name 'Security' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

    And yes, I clicked on Bin -> Add Reference... -> AntiXSSLibrary.dll and it added it to the Bin Folder including the AntiXSSLibrary.xml.

    I rebuilt the whole website, and still nothing.

    I'm using ASP .NET 3.5 C# - AntiXSSLibrary 4.0 Stable
