Just ran into this nice error while trying to generate a proxy using the SvcUtil and /reference option in a .NET 4.0 Project. Error    13    Cannot load reference assembly 'C:\MySource\bin\Debug\MyReference.dll'     The solution makes total sense as the current version of SvcUtil is for .NET 3.5 only. You can get around this by changing your path to: C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\ NETFX 4.0 Tools\ svcutil.exe Alternatively you can download the latest Microsoft Windows SDK for Windows 7 and .NET Framework 4 And then change the SvcUtil path to: C:\Program Files\Microsoft SDKs\Windows\ v7.1 \bin\NETFX 4.0 Tools\svcutil.exe Hope this helps someone.

I have just spent the last 2 hours trying to figure out why my none of my changes were reflected in the compiled SWF. Thankfully I came across this post where one of the comments had the solution. If you have a SWF named <PROJECTNAME>.swf in the html-template then deleting it will fix this issue. Apparently the existence of this file means that when you do a Build or Release Export it just copies this file and does NOT compile the latest source code. Makes sense to me! It turns out that it’s a known bug which has never been fixed, but I hope it’s been fixed in Flex Builder 4. Hope this helps someone having the same problem in the future.
