publishing a web api (net 9) is not correct

[drma-tech]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

when publishing an api to run on IIS, this file is generated

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
        </handlers>
    </system.webServer>
</configuration>

Expected Behavior

but it should be this one

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\api.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

@drma-tech How are you creating that (web.config?) file? It looks like a rudimentary form of what you want, so I'm wondering if it's expected that you start with that and modify it as necessary to arrive at something more similar to what you provided.

I don't even know anymore. It generated this way right after the first official version. And it stopped generating definitively when the first Visual Studio fix came out.

Having looked around for a while, I believe that the logic that is intended to control this mostly lives here:
https://github.com/dotnet/sdk/blob/9098fdd20c35bf5e87f5f827248fd2989d612e1b/src/WebSdk/Publish/Tasks/Tasks/TransformWebConfig.cs

It appears that that part takes a web.config and adds the parts that were successfully added. It does not, however, include the aspNetCore element or the location element. There's a template here that adds the location part but not the aspNetCore element; since it appears that TransformWebConfig is executing (hence the handler) but that location element isn't added, that suggests that projectWebConfigPath existed.

I don't know how exactly that's added, but I think it's added through Microsoft.NET.Sdk.Publish.TransformFiles.targets via the web sdk:

sdk/src/WebSdk/Publish/Targets/Microsoft.NET.Sdk.Publish.targets

Line 135 in 9098fdd

<Import Project="$(_TransformTargetsDir)Microsoft.NET.Sdk.Publish.TransformFiles.targets" Condition="Exists('$(_TransformTargetsDir)Microsoft.NET.Sdk.Publish.TransformFiles.targets')"/>

That suggests that at some point, if you specify Sdk="Microsoft.NET.Sdk.Web" then build, it should find a web.config for you and modify it to have those elements...except your base version doesn't have the right elements?

I suspect that there may be an extra file near your project file that's causing trouble, but I've gotten pretty far away from things I'm confident of. Hopefully someone who knows more about the web sdk can chime in 🙂
