The problem was that I did not do the following step. The site was going step-by-step all the way from version 8.2 to 11. If I understand correctly a new version 10 install doesn't need this. Hopefully this helps someone else.

Below was taken from the Kentico 11 upgrade doc:

Required .NET Compiler Platform

Kentico 11 requires the .NET Compiler Platform ("Roslyn") compiler to run. Installations of Kentico 10 or newer contain the Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package by default, which provides the required functionality.

However, if your project is upgraded from Kentico 9 or older, you may be missing the package. In these cases, you need to install the package before applying the upgrade:

Open your Kentico solution in Visual Studio. Right-click the main web project in the Solution Explorer and select Manage NuGet Packages. Install the Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package (version 1.0.2 or newer).

Can you provide a little more information?

Like what actual file gave this error? did you look at the Line 274 of that? etc.

Here is the error. It was being stripped because of the tags.

I'd suggest getting a hold of Kentico Support vs. posting on the Q&A mainly because Kentico 11 was just released yesterday and this could very well be a bug and Support doesn't monitor the Q & A's, not to mention your post is very vague.

Considering the V10 looks like the below, i would see if for some reason "String.Format(" got replaced with "$" for that page.

private void HandleContentCheckBox(List<UITabItem> items)
    {
        var script = String.Format(
@"var IsCMSDesk = true;
function ShowContent(show) {{
    document.getElementById('{0}').style.display = show ? 'block' : 'none';
}}", pnlContent.ClientID);

        ScriptHelper.RegisterClientScriptBlock(Control.Page, typeof(string), "UserInterfaceEditTabsControlExtender", ScriptHelper.GetScript(script));

        UpdateTabs(items);
    }

The error might be due to the compiler version being use since newer versions of c# support in place variables using the $ to prefix the string and then placing variables in curly brackets. ie.:

var date = DateTime.Now;
var dateString = $"The current date and time is {date}";
