问题
Both Visual Studio 2005 and Visual Studio 2008 is installed on my PC, but when I open a .aspx or .master file from Explorer, it opens in 2005. I would like them to open in 2008.
I could change the file associations manually, but there are quite a lot of file extensions to go through.
Is there an easy way to give all the file associations back to 2008?
回答1:
maybe this: Options -> Environment -> General -> Restore File Associations
回答2:
You should be able to do it like this.
First create a text file (assocs) with all your existing settings
assoc | findstr -i VisualStudio > assocs
Next edit this file change 8.0 to 9.0 in cases like:
.vbdproj=VisualStudio.vbdproj.8.0 -> .vbdproj=VisualStudio.vbdproj.9.0
Next save this file and run the following command to create a batch file to alter the settings:
for /f "tokens=1-10 delims==" %i in (assocs.) do @echo assoc %i=%j >> new_assocs.bat
Finally run the batch file:
new_assocs.bat
