ASP.NET 5 (ASP.NET core) - cannot work with IIS

Question

I am trying to deploy my ASP.NET 5 MVC project to a local IIS, but encountering some errors.

Error

When open (my website address) localhost:80 I have HTTP 404. I encounter the same behavior if I manually run approot\web.cmd . I think the problem is the same. In the web.cmd console web.cmd I see this output for each request (for non-static routes, static files work well):

 fail: Microsoft.Data.Entity.Query.Internal.SqlServerQueryCompilationContextFactory[1] An exception occurred in the database while iterating the results of a query. System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlClient, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. File not found. File name: 'System.Data.SqlClient, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ---> System.IO.FileNotFoundException: Could not load the specified file.

Problem

When I start dnx web from the project development directory MySolution\src\MyProject Everything is OK

My project.json

You can see that I am using dnxcore50 and have no dependency on System.Data.SqlClient .

}

My Deployment and IIS Settings

• I use File System options, for example, in manuals
• I installed the HTTP platform handler
• I used an application pool without a management environment

Conclusion

So, is there a way to fix this problem?

Answer 1

I have done it. Following are the steps I took to get it working:

• The requested page is not available because the configuration data associated with it is invalid for the page.

  • Install the HTTP platform handler
  • Ensure that ASP.NET 4.6 is enabled in the Windows components: Internet Information Servies → World Wide Services → Application Development Components → ASP.NET 4.6

• Unable to load System.Data.SqlClient

  • Add System.Data.SqlClient to project.json

• Unable to load sni.dll

  • Use x64 coreclr runtime for x64 OS.
  • Install Redistributable MS VC ++ 2012

If it still does not work ... (help me today 02/08/2016 with 1.0.0-rc1-update1): - remove all dnx time intervals - install the latest update for ASP.NET and web tools in Visual Studio - install the latest x64 in VS in deployment settings

I think this is some kind of magic, I don’t know why it works.
