When debug a TypeScript application in Google Chrome, the *.ts files are appear totally empty ?

Why I get the following error at begin running VS.NET 2015 debug IIS :

Attempt by security transparent method 'WebMatrix.WebData.PreApplicationStartCode.Start()' to access security critical method 'System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)' failed

I got a break point on the first line of Application_Start(), but Visual Studio won't break in global.asax.cs ?
