I have an ASP.NET MVC project running on .NET 4.7.2 and I'm trying to install Snowflake.Data from Nuget. WHen I do, I get a message:
The process cannot access the file '\myproject\packages\Microsoft.IdentityModel.Tokens.6.11.1\lib\net45\Microsoft.IdentityModel.Tokens.dll' because it is being used by another process.
Under Visual Studio 2019 Tools->Options I go into the Nuget package settings and make sure that the ability to check for and download missing projects in unchecked. I don't want to be installing something on Nuget that "removes" and installs a newer version of something to trigger visuals studio to try to download the older version while the newer version is being uploaded.
The output here is below, but you can see that it fails when trying to install a prerequisite
Adding package 'Microsoft.IdentityModel.Tokens.6.11.1' to folder '\myproject\packages'
This seems weird beacuse before I tried to install the Snowflake.Data package, I checked and this "Microsoft.IdentityModel.Tokens.6.11.1" was already installed so I don't know why it's trying to reinstall something already there.
