Getting rid of “There is no source code available

Question

OK, this is my own fault, but I can't seem to rescue myself.

Whenever I try to step into a class that has fields with assignments calling into .NET code, I get a dialog box that contains the text "There is no source code available for the current location.":

For instance, stepping into the constructor of the following class would give me the above message:

public class Test
{
    private Stack<String> _Dummy = new Stack<String>();
    public Test() { }
}

I assume this is because at some point I fiddled with the settings for the symbol server, but no matter what I fiddle with now, I can't seem to get rid of that message.

Where has my stupidity forgotten what it did?

---

Summary of my current options:

• [ ] Enable address-level debugging
• [x] Enable Just My Code (Managed Only)
• [ ] Enable .NET framework source stepping
• [ ] Enable source server support
• Symbol file .pdb locations - empty
• Cache symbols from symbol servers to this directory: C:\temp (empty)

Answer 1

In Solution Explorer, check your solution property page under Common Properties, Debug Source Files. If you see the assembly listed under "Do not look for these source files:", delete it and the issue should go away.

Open the solution property page

Check "Do not look for these source files"

Answer 2

This is how I solved it.

Right click your project -> Properties - > Compile -> Advanced Compile Options...

Then Set 'Generate debug info' to 'Full' from the drop down menu.

Hope that helps.

This worked for me:

1. Check the "Enable Unmanaged Code Debugging" on the properties page for the referenced *.DLL
2. Recompile referenced *.DLL
3. Remove and then re-add the referenced *.DLL to your project

Answer 4

I had the same problem, and I solved it on this way (Visual Studio 2008):

"Formato de la informacion de depuracion" to "Base de datos de programa (/Zi)"

Answer 5

See if some source files are accidentally excluded. Do properties of the solution and look at the Debug Source Files section under Common Properties.

Answer 6

This error made me go crazy as well. I was using 'AjaxControlToolkit' and had referenced it using 'Add Reference' to my project.

I deleted the 'AjaxControlToolkit' reference and added the same with 'Add Existing Item' and after that I had no problems at all...
