'There is no editor available' error in VS 2010

Question

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?

Answer 1

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 then Set as Default.

Answer 2

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:

1. Open a new command prompt window.
2. Navigate to the directory path in which you installed Visual Studio.
   _{(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.}

3. Execute the following command, where "devenv" is the name of the executable you use to start
   the Visual Studio IDE:

   devenv /resetskippkgs
   

Answer 3

Sometimes it happens because one of the references of the project are making problems.

Solution:

Build your solution to Identify the reference that is making problems, remove the reference and add it again, after rebuilding your project everything will work fine.
