We have updated our development environment from VS2010 to VS2012 but noticed the following issue: The start of the page is sometimes not rendered.
for example having something like:
<html><head><title>Title</title><script> function myFunc() {...}</script></head><body> Content</body></html>
Might sometimes be rendered as:
yFunc() {...}</script></head><body> Content</body></html>
This only happens when using the VS2012 development server, IIS and VS2010 development server work correctly. Also the issue seem to appear randomly on all pages (for 20-30% of the requests).
NOTE: The application uses WebForms and .NET 3.5
NOTE2: I've also posted this question on stackoverflow, but no one seems to know the answer: http://stackoverflow.com/questions/24155876/after-move-from-vs2010-to-vs2012-html-rendering-is-intermittently-losing-content
