Incompatible with version 2.5.40416.9020 of NuGet

Question

Sunday, February 9, 2014 8:55 PM

I'm pretty sick of this error which has been occuring in some form or other for months now.

"The schema version of 'Microsoft.AspNet.WebPages' is incompatible with version 2.5.40416.9020 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942."

Basically there is no useful information on that link page.

I'm using the latest verions of Nuget Package Manager v2.5 and WebMatrix3.  There is no reference in my sites to any other version.

I've cleared the local Nuget cache. I've uninstalled and reinstalled Nuget Extension and Gallery items as well as Webmatrix several times. I've run WebMatrix as administrator. I've re-downloaded and tried it on the Starter Site. I've started from a blank site and tried adding I've even recreated a new windows user profile.

I've uninstalled Visual Studio as I don't ever use it.

Anyone konw how overcome this problem?

I had something similar going on with WebMatrix 2.

Never was able to get rid of it.

I have stopped upgrading anything from NuGet. So far so good.

Sorry, cannot be of any more help.

Hi mudmaps,

I also have that issue.

Updated the WebMatrix and the Nuget to the latest version, however it still has the issue.

I suggest that you could submit this feedback to http://webmatrix.uservoice.com/forums/128313-webmatrix-suggestions

After that you could post the link here which will benefit to others who has the similar issue.  

Thanks

Best Regards

What helped me was this: 

1. Right click on solution in Solution explorer and pick 'manage nuget packages for solution'

2. In the upper right corner there was 'update' or 'restore' button, I don't remember exactly, but basically it updated my solutions references

After that I could successfully build solution. Hope this helps for you too.

cheers

The reported issue is with WebMatrix, not Visual Studio.

Updated the WebMatrix and the Nuget to the latest version, however it still has the issue.

I had to change the NuGet Gallery source from WebMatrix Package Source to NuGet Official Package Source, at which point I stopped getting that error. I still have other problems using NuGet in WebMatrix.
