The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request

Hi,

when I set ASPNETCORE_ENVIRONMENT to "Production" and start it for test purpose in VS I got following error:

The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request.

Any ideas?

If you run the side on IIS look in the web.config: <aspNetCore processPath="dotnet" arguments=".\TipWeb.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" startupTimeLimit="3600" requestTimeout="23:00:00" hostingModel="inprocess"> <environmentVariables> <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" /> </environmentVariables> </aspNetCore>
