We are working on a project with the new ASP.NET 5 (vNext), EF7 and AngularJS and plan to deploy the WebApp on Azure.

I've created a new Web Application on Azure and published our project via Visual Studio 2015. After publishing I'll get a 500 - Internal Server Error when I try to test our application.

I've already set <customErrors mode="Off" /> in the web.config in wwwroot without success. I've then logged in via FTP and the "DetailedErrors" also do not contain any useful information.

The eventlog.xml contains following exception:

<Events><Event><System><Provider Name="ASP.NET 4.0.30319.0"/>    <EventID>1309</EventID><Level>2</Level><Task>0</Task>    <Keywords>Keywords</Keywords><TimeCreated SystemTime="2015-07-28T10:54:43Z"/>    <EventRecordID>280293125</EventRecordID><Channel>Application</Channel>    <Computer>RD000D3A202052</Computer><Security/></System><EventData>    <Data>3005</Data><Data>An unhandled exception has occurred.</Data>    <Data>7/28/2015 10:54:43 AM</Data><Data>7/28/2015 10:54:43 AM</Data>    <Data>9df086471c304ebfa4ddddf9ca2a2b92</Data><Data>1</Data><Data>1</Data><Data>0</Data><Data>/LM/W3SVC/2082809257/ROOT-1-130825544829782705</Data><Data></Data><Data>/</Data><Data>D:\home\site\wwwroot\</Data><Data>RD000D3A202052</Data><Data></Data><Data>2108</Data><Data>w3wp.exe</Data><Data>IIS APPPOOL\appname</Data><Data>InvalidOperationException</Data><Data>Couldn't determine an appropriate version of runtime to run.

It says that it couldn't determine an appropriate version of the runtime.

In the project properties the solution DNX SDK version is set to:

  • 1.0.0-beta4
  • .NET Framework
  • x86

How can I get more information on the error?
