No exports were found that match the constraint Visual Studio 2015/2017 Community Edition.

Question

_{Friday, June 23, 2017 3:36 AM}

I am running a Visual Studio application(on Visual Studio 2015 and 2017 Community Editions), and have run into the following outcome which terminates the run;

No exports were found that match the constraint:

ContractName  MONAHRQ

RequiredTypeIdentity   Monahrq.Sdk.DataProvider.IDatabaseCreator

I have read a lot of comments that proposes a fix of renaming or deleting  the following "C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\ 15.0_f9a40a22 \ ComponentModelCache "

This troubleshooting has not worked for me.  I’d appreciate some help here.  Thanks.

Hi EKAE,

Welcome to the MSDN forum.

>> No exports were found that match the constraint:

Refer to the error message, you can have a try with the following:

1. Go to Control Panel-Programs and Features, right click the VS 2015 and choose Change-Repair, for VS 2017 you need to re-run the Visual Studio Installer and click the icon beside ‘Launch’ and select ‘Repair’
2. Clear all folders and files under the folder: %LocalAppData%\Microsoft\VisualStudio\14.0\ and %LocalAppData%\Microsoft\VisualStudio\15.0_f9a40a22, restart the VS 2015 or VS 2017 to check it again.
3. Open cmd and navigate to the VS 2015/2017 installation folder like C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE and run the command: devenv /safemode to run it as safe mode, then check if the installed extensions caused tis issue.

Meanwhile, you can have a look at this similar issue: Error message “No exports were found that match the constraint contract name” and some other solutions were mentioned and you can have a try to troubleshoot this issue, thank you for your cooperation.

Best regards,

Sara
