Deploy ASP.NET Core 2.1 Preview App to Azure

Question

Hi all,

trying my first ASP.NET Core 2.1 preview App, so I created a new ASP.NET Core 2.1 preview App from VS (15.6 - Preview 7). Everything runs OK in my local box under VS.

Then I created a new App Service on Azure, installed the Preview1 extension (as seen here) and setup the deployment with my Git Repo. When I push the code from my local box to Git, the Deployment fires-up but I get an error related to the Runtime - [ NU1102: Unable to find package Microsoft.Build.Runtime with version (>= 15.7.0-preview-000011-1378327)].

Am I missing something?

Thanks in advance.

Answer 1

You need to add the package source, so that it is able to restore packages from the preview feed (you must have added a NuGet feed on your development box).

The solution to this is adding a NuGet configuration file to the root of your solution, and adding the package feed to the configuration file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
   <packageRestore>
       <add key="enabled" value="True" />
       <add key="automatic" value="True" />
   </packageRestore>
   <packageSources>
       <add key="nuget.org" value="https://api.nuget.org/v3/" />
       <add key="dotnetpreview" value="https://dotnet.myget.org/F/aspnetcore-dev/api/" />
   </packageSources>
   <activePackageSource>
       <add key="All" value="(Aggregate source)" />
   </activePackageSource>
</configuration>
