Without more details as to what you're doing, it's difficult to go beyond "the debugger is looking for a symbol file which matches the compiled code, and couldn't find one in the folder where the compiled code lives."

Some things to think about:

<ol>
<li>Are you creating symbols as part of your compilation? (check the project properties)</li>
<li>Are you using a symbol server (if so, does it point to the right place)</li>
<li>Is this compiled code from a third party? In which case, as you apparently have the source, compile it yourself.</li>
</ol>

Consider clarifying your question if you want a better answer. Especially what do you mean by "I want use of Symbols".

One of the things I've ran into with was because debug was off on the project referenced where the code lives. In my case, I made a new configuration called "Developer" and by default debug was turned off.

I ran into this problem and the answer was simple.

Visual studio has two project level settings that can create .pdb files.

<ol>
<li>Linker: Configuration Properties -> Linker -> Debugging -> Generate
 Program Database File = "xxxx.pdb" </li>
<li>Compiler: Configuration Properties -> C/C++ -> Output Files -> Program Database File Name =
"yyyy.pdb"</li>
</ol>

You want #1 for debugging. Forget about #2. 
Give file #2 a different name than file #1 to solve this error.

I don't know why microsoft specifies #2 as a .pdb file. That is just confusing.

I found this was because the Properties => Debug => Start Action was set to Start external program instead of the Project. So the newly generated pdb file didn't match, because the actual exe was the wrong one.

blocks|key|2315111|text|对于BizTalk+(和其他)项目，这可能是因为在GAC中已经有您要调试的程序集的版本。当您运行单元测试或按F5进行调试时，新版本将在本地编译。但是，正在使用GAC中的版本，新创建的PDB与GAC中的DLL不匹配。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2315112|解决这一问题的一种方法是取消使用Configuration为所有内容(单元测试项目除外)选择构建，如下所示：|2315113|​|2315114|📷|atomic|offset|length|2315115|2315116|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://developer.qcloudimg.com/http-save/yehe-900000/fe6e8482792b115a4ad121e8b52b592e.png|imageAlt^0|0|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|W|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|X|8|@]|9|@$I|Y|J|Z|1|10]]|A|$]]|$1|K|3|E|5|6|7|11|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S|T|-4]]]]

For BizTalk (and other) projects, it could be because there's a version of the assembly you're trying to debug already in the GAC. When you run a unit test or hit F5 to debug, a new version is compiled locally. However, the version in the GAC is being used, and the newly created PDB doesn't match the DLL in the GAC.

One way around this is to deselect a build for everything except your unit test project using the Configuration Manager, as shown below:

The error I got was "a matching symbol file was not found in this folder" in the Debug => Modules window even after both the DLL and PDB were available and built together, so I was unable to debug into the target DLL referenced by my main project.

Posting this here in case it helps someone browsing with "Mixed Platform" build for target DLL. I did two things to get past this:

<ol>
<li>In the solution using the target DLL, Uncheck "Just My Code" in Tools => Options => Debugging => General => Enable Just My Code (JMC).</li>
<li>Check "Enable native code debugging" in target DLL solution in relevant Project Properties => Debug.</li>
</ol>

Well, the solution depends on your specific problem. I tried everything that could be possibly found on Stackoverflow and other sites. One of the thread that I followed is <a href="https://stackoverflow.com/questions/2155930/how-do-i-remedy-the-the-breakpoint-will-not-currently-be-hit-no-symbols-have-b?page=3&amp;tab=votes#tab-top">this</a>. That did not help too.
The problem was at once resolved when I noticed that my executable project did not contain a reference to the library that I wanted to debug. So I just added the reference to that project.

**PS: ** This problem might also arise because the assembly referenced by the executable assembly might not match that in the references. So in that case, you just remove the already existing reference and add the new one.

Hope this helps!

The same happen to me because the .pdb file of the project have not been copied to the <code>debug\Bin</code> folder, so the symbols could not be loaded from the .pdb file.

You must rebuild your project and manually copy the symbols (.pdb file) to the <code>debug\Bin</code> folder of executable project.

So, my problem was I was trying to debug my project and the debugger couldn't step-in to the in-house nugets sources. I had the source files of the nuget project. Still the visual studio didn't accept the pdb files I was trying to show it to.
Showing exact same error:
<blockquote>
a matching symbol file was not found in this folder
</blockquote>
So, what I did was I added this to the .proj file of the nugets project:
<pre><code>&lt;DebugType&gt;full&lt;/DebugType&gt;
</code></pre>
And created the dll and pdb file again using the rebuild option.
In the command line I ran:
<pre><code>.\ChkMatch.exe -m name_of_your.dll name_of_your.pdb 
</code></pre>
It said this:
<blockquote>
Writing to the debug information file...
Result: Success.
</blockquote>
Great success!
So, next, I referenced this dll instead to the proj I was trying to debug. I worked when I tried to load the symbol again.
Hope it helps.
