Azure虚拟目录Webdeploy之后的Asp.Net Core WebApi内部服务器错误

Question

I have tried to deploy a asp.net core mvc app and a asp.net core WebApi to azure.

Both should be run on same url.

I have created a virtual directory under settings: " site\\wwwroot\\webapi "

And downloaded the publish settings.

I published the mvc app to:

Sitename: example

Destination URL: http://example.azurewebsites.net

The WebApi I published to:

Sitename: example/webapi

Destination URL: http://example.azurewebsites.net/webapi

But if i try to acces the URL http://example.azurewebsites.net/webapi

i get an Error 500:

The page cannot be displayed because an internal server error has occurred.

I have spend several hours to find a solution, but i could not fix it.

Answer 1

I have solved the Problem. I created a Web.RemoveHandlers.config file next to the Web.config file i created in my project, and set its content to:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <system.webServer>
    <handlers xdt:Transform="Remove" />
  </system.webServer>
</configuration>

Then i edited my .csproj file and added:

<ItemGroup>
    <DotNetCliToolReference Include="Microsoft.DotNet.Xdt.Tools" Version="2.0.0" />
</ItemGroup>

<Target Name="RemoveHandlersFromWebConfig" AfterTargets="_TransformWebConfig">
  <PropertyGroup>
    <_SourceWebConfig>$(PublishDir)Web.config</_SourceWebConfig>
    <_XdtTransform>$(MSBuildThisFileDirectory)Web.RemoveHandlers.config</_XdtTransform>
    <_TargetWebConfig>$(PublishDir)Web.config</_TargetWebConfig>
  </PropertyGroup>
  <Exec Command="dotnet transform-xdt --xml &quot;$(_SourceWebConfig)&quot; --transform &quot;$(_XdtTransform)&quot; --output &quot;$(_TargetWebConfig)&quot;" />
</Target>

After i run dotnet restore in the Package Manager Console.

After Publishing to Azure all worked as expected.

I found this solution on:
