When setting the { output: { publicPath: 'http://localhost:5000" }} in webpack.config it results in:

System.ArgumentException: The path in 'value' must start with '/'. Parameter name: value at Microsoft.AspNetCore.Http.PathString..ctor(String value) at Microsoft.AspNetCore.Http.PathString.op_Implicit(String s) at Microsoft.AspNetCore.SpaServices.Webpack.ConditionalProxyMiddleware.<Invoke>d__5.MoveNext()

This is needed as a workaround to gets custom fonts working in dev-environment. See: http://stackoverflow.com/questions/34133808/webpack-ots-parsing-error-loading-fonts/34133809#34133809
