Could not load file or assembly Microsoft.Data.Entity.Build.Tasks.dll or one of its dependencies

I created a new project in Visual Studio 2015 and when I attempted to build, received the following error:

The "EntityClean" task could not be loaded from the assembly c:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Data.Entity.Build.Tasks.dll.
Could not load file or assembly 'file:///c:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Data.Entity.Build.Tasks.dll' or one of its dependencies

Running Node.js (npm) behind a proxy

At work I've installed and used node.js (npm) several times.  Every time I use npm it generates the following errors when it's first run:

    
    npm ERR! network connect ETIMEOUT
    npm ERR! network This is most likely not a problem with npm itself
    npm ERR! network and is related to network connectivity.
    npm ERR! network In most cases you are behind a proxy or have bad networ settings.
    npm ERR! network
    npm ERR! network If you are behind a proxy, please make sure that the
    npm ERR! network 'proxy' config is set properly.  See: 'npm help config'

These errors indicate that you Here's how I fixed it. It turns out to be pretty basic. npm uses a series of configuration settings, which can be accessed by using npm config as follows:

• call npm config list to see all of the current configuration settings
• call npm config get to retrieve the value a specific configuration setting
• call npm config delete to remove a specific configuration setting
• call npm config set to set a value for a specific configuration setting

So to fix my problem behind the firewall, I just needed to run two commands to configure my proxy:

npm config set proxy http://proxy.mycompanyname.com:8080
npm config set https-proxy http://proxy.mycompanyname.com:8080
