I have seen the posts on this site about the following error:
The breakpoint will not currently be hit. No symbols have been loaded for this document.
But, the problem descriptions and solutions haven't addressed the situation I am experiencing so, I hope to get some clarification.
I am using Visual Studio 2010, and working on a very large, somewhat old ASP.NET web application that targets .NET v2. The first page of the application is Login.aspx. If I put a break point on the first line of code within the Page_Load event of the Login.aspx page. I get the yellowed-out warning icon on the break point, with the message above. If, while in debug mode, I go to Debug >> Windows >> Modules, I see that App_Web_login.aspx.cdcab7d2.DLL has a Symbol Status that reads "No symbols loaded". The Path for the symbols is like this:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files...\App_Web_login.aspx.cdcab7d2.DLL. I have checked that path, and a DLL file does exist there. So, if I right-click on this listing in the Modules page, and select "Load symbols from " and "Symbols Path", I get a dialog box, pointing to the path I just listed but, it is asking for a .pdb file! There is no .pdb file in that directory. Actually there is no App_Web_login.aspx.cdcab7d2.pdb file anywhere on my machine.
Also, there is an App_Web_login.aspx.cdcab7d2.DLL file located in the bin folder of my project. I was hoping that Visual Studio would generate a new .dll file there if I rebuilt the project. But, if I remove that .dll file, the project won't build.
Very confusing.
How can I get the symbols file situation straightened out?
Thanks, in advance, for any help you can provide.
Special Note: Here is what is listed in the element of the web.config file:
<compilation defaultLanguage="vb" debug="true">
<compilers>
<compiler language="vb" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" extension=".VB" compilerOptions="/define:Debug=True /define:Trace=True /imports:Microsoft.VisualBasic,System,System.Collections,System.Configuration,System.Data,System.Drawing,System.Web,System.Web.UI,System.Web.UI.HtmlControls,System.Web.UI.WebControls"/>

Thanks again for any help...

I'm working on a web site project on vb.net - asp.net 4 - visual studio 2010.
I need to implement a part of code that is used only when debug compilation is chosen within visual studio, e.g.:
' do something
#if DEBUGCONST
' debug mode! do something else
#end if
' proceed as usual..
Unfortunately this is not a web application project, therefore it doesn't come with a complete "property page" (where you can change compilers constant easily).
Googling for an answer, I found:
http://msdn.microsoft.com/en-us/library/a15ebt6c%28v=vs.100%29.aspx
..and I changed my web.config in this way:
<system.codedom>
<compilers>
<compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" compilerOptions="/define:DEBUGCONST"></compiler>
</compilers>
</system.codedom>
Unfortunately, even if it compiles fine, the DEBUGCONST is never defined and the "debug code" is never executed.
Is there something I'm missing?
Thank you in advance for any help!
Two hours of searching Google and Stackoverflow and I've gotten nowhere. This is not related to code-behind, which is why I've had no luck so far.
Here's my problem: I have a legacy website running IIS6 and I need to install an HTTPModule on it to add some processing to any request for a specific file type. I've written the module, copied it over to the application's /bin directory, and added the following to my Web.config:
<system.web>
<httpModules>
<add name="YourModule" type="SecurityModule.SecurityModule" />
</httpModules>
</system.web>
Then I fire up the website and... "Server Error in /MyApplication".
Here is the entirety of what it gives me:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Could not load type 'SecurityModule.SecurityModule'. (D:\Websites\Reports\web.config line 4)
Source Error:

Source File: D:\Websites\Reports\web.config Line: 4
Version Information: Microsoft .NET Framework Version:2.0.50727.3625; ASP.NET Version:2.0.50727.3618
Line 4, where I added an arrow, is red. And that's it! No explanation, no hints on where to go. Just "Could not load type". I have tried all sorts of things to get around this:
Played with the name of the module in case I got it wrong. And the string in the type.
Changed /Bin to /bin
Make sure the module was compiled against the .NET Framework 2.0
Abandoned web.config and tried setting it up as a mapping in IIS 6 (got 404s from that one).
Related to previous, tried making all files of my extension go through the ASP.NET ISAPI module with a wildcard mapping and configuring the module. Brought me full circle back to this error.
Can anyone tell me what's going on here? Or, failing that, can someone point me in a direction? At this point, any direction will do. :) I'm at a complete dead end.
Thanks!
You should use an assembly qualified name.
NamespaceQualifiedTypeName, AssemblyName
I am currently getting the following error. On a locahost website.
Could not load file or assembly 'MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Though, the reference is definitely there in the references folder and that dll is definitely on my local machine in the place it is pointing to. I have also tried deleting and re-adding the reference.
Does anyone know what would cause this error?
Also what is the assemblys manifest definition?
Thanks in advance for the help, I very much appreciate it.
in visual studio select the reference in the solution explorer then in the properties make sure the Specific Version property is set to false.
If you have an entry for this reference in the web.config, edit the file and remove the version information.
if you close visual studio and open the project file with a text editor, make sure in the project file the version of the assembly is not listed but only the name and type, so just remove the following:
, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d'
then it should work no matter if you are using the 6.5.5 or 6.5.4, as long as the code is using classes and methods available in both.
I have experienced the same situation and managed to fix the problem with these steps,
Read the error information carefully which provides helpful details to rectify the situation.
I wouldn't change the machine.config file.
As it says Application cannot find a reference to the assembly MySql.Web and the version it is trying to reference is Version=6.7.4.0.
Based on path you install MySql you will be able to find the correct assembly files, ex :
C:\Program Files\MySQL\Connector NET 6.7.4\Assemblies\v4.0\MySql.Data.dll
Copy that file to bin folder. (I would copy all the files in C:\Program Files\MySQL\Connector NET 6.7.4\Assemblies\v4.0\ folder to bin folder)
Hope this helps! Thanks
I have encounter the same problem very few days ago , you get this error when you have build your some DLL with earlier version and now you have change the dependent DLL version but had not build the DLL again . Please check if you have any component which was build on the earlier version . While we build any DLL , DLL it self in the manifest add all the dependency information so that it can load all of them when required . So if you remove that version of DLL you need to recompile all the component and then use
This problem persists also in newer version of MySql.Data. Just change the version from App.config file:
<assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.6.5.0" newVersion="6.6.5.0" />6.7.4.0
to oldVersion="6.6.5.0"
<assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
<bindingRedirect oldVersion="6.6.5.0" newVersion="6.7.4.0" />
I had this in an older asp.net 2.0 website on a new machine. In my case, the MySql assembly from the GAC could not be loaded because it was .Net 4.0. Assembly redirect in web.config did not work. I fixed it as follows:
Download the specific version of MySql.Web and MySql.Data from nuget:
https://www.nuget.org/api/v2/package/MySql.Web/6.5.4
https://www.nuget.org/api/v2/package/MySql.Data/6.5.4
Open the downloaded packages with a zip tool (e.g., 7zip) and extract the .Net 2.0 assemblies into the bin directory of the malfunctioning asp.net site.
I was getting the same error and the file absolutely existed.
If you see a SGEN next to your error, you can try this:
In the project properties window go to Build and in the Output section go to the Generate serialization assembly dropdown. Change the value Auto to Off and Build again.
You can set it back to auto if you need it.
In some situations, it depends on bindingRedirect attributes in web.config file of the project. In my case, I had two version: olderVersion and newVersion. I just switched those values and it solves the problem.
WARNING: Be sure that the newer version is referenced into web.config assemblies' tag file just as :
<add assembly="$AssemblyName", Version=$NewVersion, Culture=neutral, PublicKeyToken=$KeyToken/>
I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)".
I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project.
The build only fails when I switch the Solution Configuration to "Release". It does not fail when the Solution Configuration is set to "Debug".
The only difference between the two configurations (that I know of) is shown in the following Web.config transform, Web.Release.config:
<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<connectionStrings>
<add name="SqlServer" connectionString="" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>

I have tried using Fusion Log Viewer to track down the assembly binding issue, but it looks like it is finding and loading the assembly correctly. Here is the log:

I feel like there is a fundamental lack of understanding on my part as to what exactly is going on here. Any explanation/help is much appreciated!
Could be too late, I've experienced this issue. In my case, I fixed following this instructions I found in a comment (Thanks Thomas!) in this post
In the 'Developer IT' comment talks about do the same in the app.config. Actually must be in other place. Follow the instructions behind.
An even better solution is to "fix" Microsoft's sgen distribution. First find sgen (for example, on my system for .Net 4.0 it is in "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools".) Next, create the file sgen.exe.config with the contents:
<configuration>
<runtime>
<loadFromRemoteSources enabled="true" />
</runtime>
</configuration>
The point is, adding loadFromRemoteResources set to true in the sgen app config file allows sgen to properly load files from ClearCase volumes. I know. I've run into the same problem and this is how I fixed it.
Note that at some point Microsoft may create the app config file, so if you do this, first check that the file doesn't already exist, and if it does, check if it still needs the setting.
I realise this is a slightly late reply, but I've just experienced and fixed the exact same issue with Elmah in release mode (and as with the OP, debug mode was working fine).
I fixed my issue by modifying the properties for Elmah.dll in Windows Explorer - from the general tab, I had to click Unblock to convince explorer that the file was indeed safe. After that, release mode publishes worked fine.
According to blogs here and here, the cause might be related to an untrusted assembly. If this were the case, I can't imagine why it would work in one configuration and not the other, but it's at least something to look at.
Problem may have multiple causes.
Appears to be exposed when loading mixed-mode assemblies (compiled in "ANY_CPU" and "X86" mode.)
I revised the compile option for my main program to "X86" to match the assumed mode of the component DLLs. The problem went away.
It may have something to do with the order in which the dll files are loaded.
I've been using a MS ReportViewer component in a website for a while now, but recently I've been getting the error shown below.
Parser Error Message: The base class
includes the field 'xyz', but its
type
(Microsoft.Reporting.WebForms.ReportViewer)
is not compatible with the type of
control
(Microsoft.Reporting.WebForms.ReportViewer).
<rsweb:ReportViewer ID="xyz" runat="server" Width="100%" Font-Names="Verdana" Font-Size="8pt" Height="400px" ProcessingMode="Local" ShowExportControls="false">
Now, I get this error in Visual Studio as well as in production. I have the ReportViewer Redistributable installed in production.
Am I somehow missing a reference in my project, or something?
I discovered the answer: Somehow the reference to version 9 of Microsoft.Reporting.WebForms got switched to version 8. This caused the error. So deleting the reference and adding in the correct version of the reference seems to have fixed the problem.
Edit:
Well, according to the previous version of the .vbproj file, it was a reference to 9, despite that the project references properties screen told me 8. In short I'm not really sure what managed to get screwed up, but it seems to be working now.
If anyone has experienced this or has some insight, please contribute.
Following a clean install, my project didn't compile because the reference to the dll was broken, so I deleted it and added it again, then the web page where the ReportViewer is used gave a parser error:
The base class includes the field 'rprtReportsViewer', but its type (Microsoft.Reporting.WebForms.ReportViewer) is not compatible with the type of control (Microsoft.Reporting.WebForms.ReportViewer).
I found a reference on the webpage with version number different to the one I had just added:
<%# Register Assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
I changed the version to 9.0.0.0, and this time got a compiler error when I refreshed the page:
CS0433: The type 'Microsoft.Reporting.WebForms.ReportViewer' exists in both 'c:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\8.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' and 'c:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\9.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll'
I then searched the solution for "Microsoft.ReportViewer" and found more references in compilation.config:
<add assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="Microsoft.ReportViewer.Common, Version=8.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
</assemblies>
<buildProviders>
<add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.Common, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</buildProviders>
I changed the version numbers here too and it stopped the errors
You may also need to Remove from \bin files:
Microsoft.ReportViewer.Common.dll
Microsoft.ReportViewer.ProcessingObjectModel.dll
Microsoft.ReportViewer.WebForms.dll
Microsoft.ReportViewer.WinForms.dll
I just moved them into a sub directory.
Check your page rdlc version like
<%# Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
Having the same issue. Clean Windows 2008 Server install with SQL Server 2005 and SQL Reporting. The server hosts the site. Installed ReportViewer 2008 SP1. Web.config references version 9.0.0.0.
The same error message comes up: The base class includes the field but its type (Microsoft.Reporting.WebForms.ReportViewer) is not compatible with the type of control (Microsoft.Reporting.WebForms.ReportViewer).
Searched online and lots of people experience the same issue. Some people suggest manually editing project file.
I managed to fix it by setting Specific Version = True (Version=9.0.0.0) in the Solution Explorer->[Web Project Name]->References->Microsoft.Reporting.WebForms->Properties.
In one of the environments we also found Microsoft.Reporting dlls in the web bin folder. And, they were conflicting with the dlls registered in the GAC. Deleting of the dlls solved the issue.
I had this problem on a Production server. I installed the correct version of ReportViewer and made sure all the references in the project were pointing at the correct version. However, I was still getting errors.
Eventually I solved the problem by going to 'Temporary ASP.NET Files' and deleting the files for my app. To do this you'll need to stop the app first. This then solved the problem. On DEV servers I had not encountered this problem because after installing ReportViewer I re-started the machine.
Hope this helps someone. I pulled a lot of hair out before I solved this particular 'challenge'.
References -> (Microsoft.ReportViewer.WebForms), click the right mouse button.
The Specify Version option, leave it as false.
After that, just save and run again.
I came across the same error. What worked for me was to delete the reference Microsoft.ReportViewer.WebForms and add it again.
