I am getting the following error when I try to launch my ASP.Net Core App using IIS Server v7.5 ... I published the website (File System option in Visual Studio) to a specific directory successfully. It launches fine from approot/web.cmd file. But when I try to hook it up to IIS Server and point it to the wwwroot folder, I get the following error:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
- Detailed Error Information
- Module IIS Web Core
- Notification Unknown
- Handler Not yet determined
- Error Code 0x8007000d

Below are two different web.config files I tried any neither one worked. When I try to get into Configuration Editor within IIS, I get an unclear error as well. Any help would be greatly appreciated!!!
<configuration> <system.web> <httpRuntime maxQueryStringLength="64768" maxUrlLength="65536" /> </system.web> <system.webServer> <security> <requestFiltering> <requestLimits maxQueryString="64768" /> </requestFiltering> </security> <handlers> <add name="httpplatformhandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" /> </handlers> <httpPlatform processPath="..\approot\web.cmd" arguments="" stdoutLogEnabled="false" stdoutLogFile="..\logs\stdout.log" startupTimeLimit="3600"></httpPlatform> </system.webServer> </configuration>
Web.config #2 -gets the same error
<configuration> <system.webServer> <handlers> <add name="httpplatformhandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" /> </handlers> <httpPlatform processPath="..\approot\web.cmd" arguments="" stdoutLogEnabled="false" stdoutLogFile="..\logs\stdout.log" startupTimeLimit="3600"></httpPlatform> </system.webServer> </configuration>
I was getting this error. I fixed this error by installing the .NET Core Windows Server Hosting bundle (vs the Runtime Bundle), as described in instructions like this one.
Install the .NET Core Hosting Bundle
Install the .NET Core Hosting Bundle on the hosting system. The bundle installs the .NET Core Runtime, .NET Core Library, and the ASP.NET Core Module. The module creates the reverse proxy between IIS and the Kestrel server. If the system doesn't have an Internet connection, obtain and install the Microsoft Visual C++ 2015 Redistributable before installing the .NET Core Hosting Bundle.
As @Patrick says you can download the bundle installables from this link.
After installing that Module, my app served (i.e. no 500 error).
I see @Jørgen made this comment on OP already, so he gets credit.
EDIT Please confirm you install the Hosting bundle vs the Runtime Bundle per comment by @MDave
Did you install the .NET Core Windows Server Hosting bundle? This is needed for IIS to work as a reverse proxy for the .net core libraries. You'll find the link in this article: docs.microsoft.com/en-us/aspnet/core/publishing/iis I had the same problem before installing this on my dev machine. – Jørgen Tvedt Mar 28 at 6:31
The only solution worked for me was to install 2 more items from Microsoft dot net core library:
This worked for me, delete file:
project.lock.json and run
restart visual studio.
I was able to solve this same problem when running in Visual Studio Community 2017 v. 15.7.1.
Had to install the latest dotnet-sdk-2.1.300-rc1-008673-win-x64.
