Error message “No exports were found that match th

Question

This morning I faced a problem while opening my Visual Studio solution, and when I tried to run it, it said:

No exports were found that match the constraint contract name

How can I fix this problem?

Answer 1

I am using Visual Studio 2012. After installing the Visual Studio 2013 web express, when I want to run or open any project in Visual Studio 2012 it shows me the following error:

"no exports were found that match the constraint contract name".

I also tried the above solution for clearing the ComponentModelCache, but I did not find the folder. I solves my problem just by: Repair Visual Studio 2012

For the Express versions of the software, the folder you need is in a slightly different place(s): For Express 2012 for Web it is C:\Users\XXXXXXXX\AppData\Local\Microsoft\VWDExpress - not in the Visual Studio folder.

This happened to me with Visual Studio 2013 Web, after Windows installed several updates. Unfortunately none of the suggestions in this thread helped.

I had to re-run the installer and select the "Repair" option. After that (and a reboot) it was working once again.

In some cases you may have to repair more than one version of Visual Studio. One example is when a Script Task control in VS 2013 opens VS 2012 when you click Edit Script.

Renaming the ComponentModelCache folder worked for me in Visual Studio 2015, but with a slightly different path:

%AppData%\..\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

Answer 4

Clearing the folders didn't work for me. So I went to 'Programs and Features' and used the change button to startup the Visual Studio 2013 setup.

In the setup I choose the repair function and that fixed the problem for me.

Answer 5

i experienced this problem in Microsoft Visual Studio Express 2012 for windows phone while trying to open file.

Then i browsed to

C:\Users\MyUserName\AppData\Local\Microsoft\VPDExpress\11.0\ComponentModelCache

And Inside ComponentModelCache i deleted Microsoft.VisualStudio.Default.cache CACHE file. Finaly i restarted visual studio and reopened my project.

Then my problem was solved, i was able to open file.

Note: My OS is windows 8. And i installed SDK 8 for developing windows phone app

Thanks
