A breakpoint could not be inserted at this locatio

问题:

I can't set a breakpoint in JavaScript files in my MVC projects in Visual Studio Community 2015 Update 3. I get this error at bottom left of Visual Studio.

A breakpoint could not be inserted at this location

I can set breakpoints in C# files, but not JavaScript files.

Here is what I've done so far to troubleshoot:

• checked web.config includes: compilation debug="true"
• solution configuation set to "Debug"
• browser is Internet Explorer
• added BundleTable.EnableOptimizations = false; to BundleConfig.cs
• tried adding breakpoints in both generated files during debugging as well as source code JS files when not running
• Rebuilt project, restarted Visual Studio
• Repaired Visual Studio
• Created new projects with both .Net Framework 4.5.2 and 4.6.1
• also tried all suggestions listed in this post Breakpoint Failed to Bind - Visual Studio 2015

You really can't debug a javascript code on vs2015 and below but on vs2017 its already possible. Just make sure to Enable JavaScript debugging for ASP.NET by going to Debug>Debugging>General menu.

Set 'Configuration Manager' => Debug
