Cannot find .cs files for debugging .NET source code
<p>I tried setting up debugging the .NET source by following this <a href="https://msdn.microsoft.com/en-us/library/cc667410.aspx" rel="noreferrer">MDSN walkthrough</a>. The Symbol cache is setup properly, as is the check 'Enable .NET Framework source stepping'. </p>

<p>But subsequently, whenever I want to step into .NET code, I am prompted to specify the location of the relevant cs file. The error message is
<code>You need to find &lt;filename&gt;.cs to view the source for the current call stack frame</code> and <code>The debugger could not locate the source file &lt;filename&gt;.cs</code>.</p>

<p>I am offered to browse for the file (but I don't have it) or view a disassembly (but I don't want that). </p>

<p>How to step into the .NET source code?</p>
