Exception on Installation

[rdugre]

When I try to install the NuGet package "Westwind.Globalization.Web" (version 2.2.0), I get the following exception. This prevents it from being installed properly. Any ideas?

System.IO.IOException: The process cannot access the file 'C:\Users\rob\.nuget\packages\Westwind.Globalization.Web\2.2.0\Westwind.Globalization.Web.2.2.0.nupkg' because it is being used by another process.

I was able to successfully install version 2.1.0. Also, I am developing an ASP.NET 4.51 Web project (in C#) and with Visual Studio 2015 (v14.0.23107.0)... in case any of that helps.

Once I am on version 2.1.0, I am not able to upgrade to version 2.2.0.

Not sure why you're seeing that. I can install just fine.

Can you give more details exactly on what you're doing? What type of project? Was there a previous install? Is an application running since it seems like there are locked files? Could it be a permissions problem of some sort?

It sounds like you already have the file in your project and the file is in use somehow (not sure how that would happen really since ASP.NET shadow copies). Try shutting down VS and then doing an install of 2.20 after you open the project.

Ok - we had some odd issues with the package that caused problems for some people but not for others (including me after a few attempts).

I pushed a new package to NuGet today (2.2.1) and it looks like that's working more reliably. Not sure what went wrong - it looks some odd NuGet issue when the package was published.

Please give a try with the latest and see if the problem goes away.

Yes, it appears to be installing properly now. Thanks for looking into this for me!

Thanks for the feedback!
