Wow. The feature that shows related questions WHILE making the questions is very nice. Unfortunately, none of the questions addressed my problem, nor did any of my searches worked. I did find several questions with the same problem I'm having, but none of the solutions have worked for me.
My development laptop is WinXP with IIS 5.1. I'm developing a Silverlight 4 application. Everything was working 100% perfectly, even without registering MIME Types in IIS. Last Thursday, VS.NET stopped debugging my application and the area where Silverlight was supposed to show was being left blank and there were no java errors shown by Internet Explorer 8. I got the same behavior in Firefox 4. If I right-clicked on the blank area, the usual Silverlight context menu showed up and I could see the settings.
Using Fiddler I noticed that the browser makes the request to the correct file, but it looked like the server either hangs or did not respond with the file stream. With this information I browsed my virtual directory using the browser and tried downloading the file with a right-click/save-as, but the browser just hanged waiting for a response from the server.
Tweaking the source code I noticed that, if I comment some code (any code at random, no code specifically, as long as no compile time error shows up), the application starts showing the log-in page correctly and I can download the XAP file correctly again. If I un-comment the code, the log-in stops working again and I cannot download the XAP file anymore.
I already tried registering MIME types in IIS (and double and triple checking I was writing the entries correctly), double and triple checking that the XAP file address was correct, tried changing the XAP extension to ZIP, and reinstalling Silverlight 4 Tools for VS.NET 2010.
At some time I thought it might be something about the XAP file size, which sits at 512K working or not. So I placed a 30MB file in the same directory as the XAP file. However, when I try to download the 30MB file, the download starts successfully.
For example, using directory browsing, the file shows 523587 bytes in length. This can be downloaded normally. If I un-comment whatever code I commented, the file shows 524194 bytes and the download stops working.
One last thing, I checked the Even Viewer and noticed an error thrown by ASP.NET. "aspnet_wp.exe (PID: 2100) stopped unexpectedly." Googled about this error and most hits took me to a virus and several tools for its removal. Tried the tools as well and all of them reported not finding any indication of the virus.

I upgraded from 10.3 (Rio) to 10.4 (Sydney) (with side-by-side installs), now having IDE docking exception, e.g.
Loading the desktop from "C:\Users\gary.walker\AppData\Roaming\Embarcadero\BDS\21.0\Default Layout.dst" for doc host windows "DockSite3" failed with message:
"EAccessViolation: Access violation at address 50165CBF in module 'rtl270.bpl'. Read of address 33DEEBFF"
Deleting all .dst files has resolved the issue in at least one case (a coworker).
Also, when attempting to debug a program, I was having a hard failure during debug startup that prevented debugger use, before application began execution. I resolved this problem by copying my Default desktop to my debug desktop.
Another friend had pretty much the same issue and was able to fix it, unfortunately he does not know how he fixed it.
Question is does anyone know how to fix this?
I am still waiting for an answer from Embarcadero and this is causing us real problems at the moment.
I received an answer from Embarcadero support.
It fixed the problem for me until I adjusted my desktops to the way I wanted them and them - still better than nothing. I suspect there is no solid work-around at this point in time. But, this may work well as long as you are not frequently changing your desktop layouts.
There were display layout changes introduced in 10.4.1 that cause the errors that you are seeing.
Shut the IDE down
In Windows Explorer navigate to: %AppData%\Embarcadero\BDS\21.0
Delete the *.dst files at that location (you can back them up first if desired)
In Windows Explorer navigate to the product's \bin directory. The default location is: 4. C:\Program Files (x86)\Embarcadero\Studio\21.0\bin
Copy the three default *.dst files from this location to the location in step 2
Start the IDE as normal
I'm trying to get line numbers to display in my silverlight stack trace - for this I need the pdb files deployed with the xap. I've tried including them in the Xap file (xap file stops working), and deploying them on the web server (with appropriate mime type set for pdbs), but nothing seems to work. I can get IL offset of the failure, but would prefer to get the full line number when debugging issues outside of production.
Does anyone have any suggestions? Is this possible?
After too many hours of research I have come up with nothing to solve this problem.
I am running a WPF program in an .xbap page file being hosted on internet explorer. Running the project in Visual Studio 2010 works just fine and generates no errors.
I want to be able to host the webpage on IIS 7.0 and to browse to it with a windows forms application. To test this I created a new website on port 80 in IIS manager. I then published the project to the local website folder and added the autogenerated project certificate file (projectName_TemporaryKey.pfx) to my Trusted Publishers and Trusted Root Certification Authorities.
My problem is this: whenever I try to browse to the file with internet explorer or with my windows forms program, the wpf program stops working. When pulling up the just-in-time debugger, I am informed that there is a System.ExecutionEngineException but am given no source code, no stack trace, and no data outside of an empty Dictionary enumerable. My guess is that this might have something to do with the database call made in the program to another machine, but I can't prove that.
I've tried several things to solve this including repairing my .NET 4.0 framework and altering permissions but nothing seems to be affect the error.
Does anyone know of a way to get more information on this error, or perhaps a step I may have missed when publishing this project?
Thanks very much.
Some things to check:
Windows event log often includes additional exception information (although usually in an awful format)
Output some trace information from your application so you can follow what's happening
Try attaching a debugger to the WPFHost and then stepping through the code
I'm not sure if this is the right forum or not, since I have no idea what's causing this problem. I have a WPF application that was compiled into a setup project. After building the setup project, there are two files: setup.exe and [Program Name].msi. I put both files in the same directory in an ASP.NET website, served via IIS 7.5. Everything was working fine for about a week, until I started getting the error:
"An error occured while downloading a
required file. You may retry
downloading the file or cancel setup."
This happens when I click on a link on my website for the setup.exe file. After seeing this error, there's a tab labeled "Details" which I can click to display the message:
"An error occurred trying to download
'[website url for the .msi file]'. See
the setup log file located at
'C:\Users[username]\AppData\Local\Temp[some
alphanumeric
sequence].tmp\install.log' for more
information."
I looked at this file, but it just restates that there was a problem downloading the .msi file. Can anyone offer me some suggestions? I'm really stumped on this, and have no idea where to go...
Many thanks for the help!

EDIT: This appears to be a problem with the computer that I'm downloading the program to. I tried downloading and installing the program on a different computer, and everything worked fine. Apparently, I must have changed some setting on my computer to cause this, although I'm not sure what that is...
So you're trying to download these files directly? Could the server be preventing the download of the .msi file type? How is the download taking place? Is it user initiated?
I was experiencing the same issue this morning and I finally figured out that it caused by either one (or both) of the following settings in IIS:
Compression: I had compression enabled for both static and dynamic files
Output Caching: I had bit Enable cache and Enable Kernel Cache enabled
I cleared all of the above check boxes and after that the setup.exe downloaded the MSI without a problem!
You connection was interrupted just try the preview command you type and also check your connection
I spent some time debugging a SL3 application with VS 2010 in IE9 beta today and noticed a few quirks. Sometimes when launching the Silverlight app in VS it fails to load in the browser, but refreshing with F5 tends to fix the problem. Also, there are sporadic scripting errors that pop up a debug dialog - these also seem to be fixed by refreshing the page. Has anyone run into these problems and found a fix?
EDIT: My most prevalent error is:
Error: ASP.NET Ajax client-side framework failed to load.
I don't understand why, but someone without a name at the Silverlight forums has found a solution that worked for me:
Just add or uncomment this entry to your hosts file (%SystemRoot%\system32\drivers\etc\hosts):
127.0.0.1 localhost
I noticed this as well with Silverlight 4, but also when I start a simple web project.
IE9 has a shorter startup time that IE8. Debugging a Silverlight application starts the development web server to host the http:// site. The time that it took to start up the web server was less than the time to start up IE8 and greater than the time it takes to start up IE9.
#Michael S. Scherotter - It can't be because of the shorter startup time because making the host file change which fixed it for me would have zero impact on app startup time. Something else must be causing the browser and Cassini to not talk to each other correctly.
One other fix, related to the others is to change the StartURL to launch to the loop back address directly, rather than editing the hosts file. So, in one app, I've got this as the start URL:
http://127.0.0.1.:60525/
Of course, to make this work consistently, I've selected a "specific port" in configuration, as 60525 in this case.
(the trailing . after the loop back address is to allow Fiddler to do its magic).
