A possible solution that worked for me is that I added this to my publish profile in Visual Studio:

<pre><code>&lt;PublishWithAspNetCoreTargetManifest&gt;False&lt;/PublishWithAspNetCoreTargetManifest&gt;

I believe this will make the host use the required files to run the app instead of relying on specifications set in a target manifest which could be wrong (either the runtime/sdk on server or your local is in conflict with these specifications).

I had published a new .NET Core 2.0 web app to Azure App Service and hit this error.

Hitting the site:

Solution

<a href="http://stackoverflow.com/a/46277882/878612">This answer: Deleting the wwwroot folder</a> in azure and publish again from VS, worked for me despite not having a legacy Core 1.1 app initially. 

Launch Azure Console within the app and delete the contents of the wwwroot folder then redeploy.

<code>RMDIR wwwroot /S /Q</code>

Further testing
Following this was very helpful for testing and it works when followed identically, then deviate however you need to find errors.

I had this problem as well and thought I'd post my solution.
I'm not sure if this is intended or not, but I don't think dotnet core 2 supports Space characters in your Project Name.

I created and published a Project called "Mikes App" and when trying to run the site with IIS I would get this error (.NET Core app unable to start in IIS due to ErrorCode = '0x80004005'). When I enabled stdoutLogs through the web.config file I found the error:

<blockquote>
 No executable found matching command "dotnet-.\Mikes" 
</blockquote>

Which I found strange because the web.config file did correctly show the dll path under arguments which was ".\Mikes App.dll"

<pre><code>&lt;aspNetCore processPath="dotnet" arguments=".\Mikes App.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" /&gt;
</code></pre>

I created a new dotnet core 2 project in Visual Studio and named it "Mikes-App" instead, re-published it and updated the directory on my IIS site. 

Then the site worked fine!

I'm running on IIS, and I had error 0x80004005 : 0, which I found in the Event Viewer -> Application Logs. It was being caused because my application pool did not have access to the website folder location.

blocks|key|392202|text|我发现您必须安装与您在VS2017中编译的版本完全相同的宿主版本。后来的版本并不是向后兼容的(至少我没有尝试过)。因此，2.2.8不会运行2.2.1版本，即使您希望有一个较小的修订来这样做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|392203|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've found you have to install the hosting version that is exactly the same as what you have compiled in VS2017. Later versions aren't backwards compatible (at least none I've tried are). So 2.2.8 won't run a 2.2.1 version, for example, even though you would expect a minor revision to do so.

Solution
You need to close the VS Project and delete <code>.vs</code> hidden folder located in your project folder and restart your VS Project.
You have to Enable Hidden Items option from Windows Explorer so that you can view the hidden .vs folder.

I have a .NET Core application. It runs locally with VS2017 and Kestrel. It runs locally under IIS. However, on the server it fails to start with a <code>502.5 - Process Failure</code> message.

In the event logs I get more detail:

<blockquote>
 Application '...' with physical root 'C:...\my-app-folder\' failed to start process with commandline '"dotnet" .\MyApp.dll', ErrorCode = '0x80004005 : 80008083.
</blockquote>

Previous builds of the application work fine on the same server, the only difference being that they were published with VS2017RC (2&amp;3) and this is the first build with the fully released VS2017.

What does <code>ErrorCode = '0x80004005 : 80008083.</code> mean?

How do I fix it?

.NET Core app unable to start in IIS due to ErrorCode = '0x80004005 : 80008083
