    <p>You need many more files that just those three to reliably debug / reproduce / analyze issues from the field. Basically, you need all of them (Windows, CLR, and (managed) .NET framework). </p> <p>I'm not aware of any repository for just some files. You'd have to install the respective versions.</p> <p>While you can install multiple versions of .NET CLR (1.1, 2.0, 4.0) on same box, and load the correct SOS.dll into WinDBG via the .loadby command, you would probably have to have multiple Windows installations for those Versions you support.</p> <p>In addition, you also need the (public) symbols for those components, including the (private) symbols for your own application, to do any meaningful debugging. </p> <p>Considering you have 3 versions of your application shipped and still supported, running on 4 operating system versions still supported by you (say Windows Vista SP1, Windows 7, Windows 7 SP1 and Windows 8), that gives you 12 combinations to have symbols for.</p> <p>That is what symbol servers are for. You could use the public microsoft symbol server, but that (of course) doesn't contain symbols for your very own application.</p> <p>Given the scope/size of the application you describe, I'd say it would be well in order to set up an in-house symbol server. That can keep all the symbols of the different versions of your app that are still in use by customers (a task not to take lightly).</p> <p>Suggested reading:</p> <ul> <li><a href="http://entland.homelinux.com/blog/2006/07/06/setting-up-a-symbol-server/" rel="nofollow noreferrer">Setting up a symbol server</a></li> <li><a href="https://stackoverflow.com/questions/2233376/what-does-setting-up-a-symbol-server-give-me">What does setting up a symbol server give me (SO)</a></li> <li><a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms680693(v=vs.85).aspx" rel="nofollow noreferrer">Symbol servers and symbol stores (MSDN)</a></li> <li><a href="http://support.microsoft.com/kb/311503" rel="nofollow noreferrer">Use the Microsoft Symbol Server to obtain debug symbol files</a></li> </ul> <p>You could also consider setting up a <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms680641(v=vs.85).aspx" rel="nofollow noreferrer">source server</a> to allow you fetching the correct version of your sources, inside a debugging session, from source control.</p>

    1. COHow does symbol server help? The user needs a dll's, not symbols.

    2. CO@SevaTitov yes, he needs binaries as well, I neglected that part, sorry. But to do any meaningful debugging he'll need symbols as well.

    3. COHi Christian, thanks for your response, but I already have the symbols sorted out. I can set the symbol path to my private symbols, and .symfix+ works a treat for the framework symbols. The real issue is that before you can even connect the debugger to a .net minidump in a meaningful way, you need the matching version of the 3 dll's mentioned above. Most people working on web based ASP.Net client-server applications don't have this issue because they can just log on to their production server and grab the versions of these dll's from there. I don't have this luxury.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
