ASP.NET sgen.exe fails during build

Question

I have a Web site with ASP.NET in VS 2022. When I add a web service reference I get an error on publishing: "sgen.exe" ended with Code 1.
In the internet I found the solution: "Go to the project properties and click on the Build tab and set the value of the "Generate Serialization Assembly" dropdown to "Off".
But this brings nothing to me. When I delete the web service reference it works. What else can I do?

Hi @Uwe Domschke,

In the internet I found the solution: "Go to the project properties and click on the Build tab and set the value of the "Generate Serialization Assembly" dropdown to "Off".

Have you tried rebuilding the project after performing this step? Maybe you could try setting the value of the "Generate Serialization Assembly" dropdown to "Off" and re-add the web service reference.

Or try disabling it again in the project file:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
                :
    <GenerateSerializationAssemblies>Off</GenerateSerializationAssemblies>
                :
</PropertyGroup>

Best regards,
Lan Huang
