ASP.NET Core 2.0 Preview 2 on IIS error 502.5

Question

I use asp.net core 2 Preview 2.

I opened stdoutLogEnabled = "true" in web.config but the system does not write logs.

Deploying on windows server 2012 r2 gives :

Error

HTTP Error 502.5 - Process Failure.

Web.config

<aspNetCore processPath="dotnet" arguments=".\App.WebHost.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" />

Logs

Please help me.

Do you use default web host setup? Have you installed hosting bundle onto PC with IIS? — Andrii, Jul 26 '17 at 18:42

I had this same problem, even after installing the hosting bundle. The solution was in the documentation -

Restart the system or execute net stop was /y followed by net start w3svc from a command prompt to pick up a change to the system PATH.

This is done after installing the .NET Core Windows server hosting bundle.

Try to install .NET Core SDK on the server:

It solved the same problem for me.

You need add this to your project :

Try using exact location of dotnet.exe in web.config processPath="dotnet", i.e. In my case C:\Program Files(x86)\dotnet\dotnet.exe

Brand new .net core 2.1 app trying to deploy to new Azure app service with new app service plan. Same issues, namely 502.5 error ( HTTP Error 502.5 - Process Failure ).

I implemented the above steps and still ran into errors. I opted to use the chose the self-contained deployment mode (compared to framework dependent (win-x64)).

This resolved my issue.

This answer was also submitted to [question]: .net-core-2.0 azure app service 502.5 error

Perhaps these questions should be linked.

I had the same problem

You must install "Windows Hosting Bundle"

This is the newest version 2.1.0 and supports the old version

The same issue occurred then got resolved to follow below steps.

1: First delete .bin and.obj folder......mean Clean your application.

2: Definitely this is version mismatching issue to see this >> go to "ASP.Net Core WebServer" in the Output window to see action error. In VS 2017, My case . 2.1.4 at [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App] AdminLTE> It was not possible to find any compatible framework version AdminLTE> The specified framework 'Microsoft.AspNetCore.App', version '2.1.5' was not found.

3: Install Microsoft.AspNetCore.App 2.1.5 (for mine) through package manager console.

4: Rebuild again then issue got fixed.

Please reply if still getting the same issue.

First you have to check the required dot net version, Confirm the same version applied in both server and developed local machine. Using Command prompt :

>dotnet --info

Solution 2:

Execute the dll file using command prompt with dotnet interpreter

YOUR_DLL_PATH> dotnet yourdllpath.dll

By this you can find the actual error.

Good luck
