When I tried to select designer view in VS 2010 I get this error:
There is no editor available for 'c:\user\teadrinkinggeek\documents\visual studio 2010\websites\website2\About.aspx'.
Make sure the application for the file type (.aspx) is installed.
I opened a different website and the error is still there.
How do I resolve this?
To solve that issue just check your reference and fix those that has "!".
This happened to me also: related/additional notes related to this fix.
Solution Explorer
--> Expand References
--> Right click on the item with "Yellow Triange w/ "!" point"
Open the "Build" Menu at the top
--> select: Rebuild "filename"
Double clicking on the from name in Solution Explorer would then open the from normally for me.
I had this issue and it was easly resolved by the following:
Right-Click on the .edmx file --> Open With --> ADO.NET Entity Data Model Designer
and thenSet as Default
.I made a ‘painful’ decision to uninstall all things related to VS 2010, and re-install from scratch. After 6 hours of troubleshooting, re-installing VS 2010 again, it worked.
Note: I initially run Visual Web Developer side-by-side with VS 2010. I uninstalled that package too. Maybe the two packages caused the problem? However I spoke to one developer on Twitter, he said he had no problem with both packages working side-by-side. Maybe it was the way I initially installed them.
If you have the same problem, please backup your work, projects etc, before you uninstall, otherwise you might run into more problems.
Well I faced the same issue. I right clicked on edmx file and opened it with Entity Data model designer. Hope this helps.
This problem is somewhat difficult to diagnose. The easiest thing is probably to re-install your copy of Visual Studio. Most likely, something got corrupted during the installation, or you failed to install a crucial component required for opening ASPX files.
Aside from that, there is one trick that I've seen work before. I suppose it's worth a try before you go through the trouble of re-installing. Here are the steps:
(I have no experience with the Express editions, so I'm not sure if the paths and names of the executables are the same as the
full versions. I suspect they're probably not. Thus, the best way to get this information is right-clicking on your shortcut icon.
Execute the following command, where "
devenv
" is the name of the executable you use to startthe Visual Studio IDE:
I've also encountered the same problem in Visual Studio 2008. But don't worry folks it's damn simple to solve.
