auto-generated code causes build error

[JurjendeGroot]

I am using Csla v5.4.0 (in the ABP.IO framework)

When Building the solution in VS2019 (16.9.4) the following 'code' is generated in my Blazor project (in the obj folder) and causes a build-error (below). At this time since I'm still developing I just mark that line as comment and then all is well until I do another build. However I expect problems down the road when building in a devops pipeline...

Is there some way, an option or setting, to prevent this code being generated ?

[assembly: Microsoft.AspNetCore.Mvc.ApplicationParts.ApplicationPartAttribute("Csla.AspNetCore")]

// Generated by the MSBuild WriteCodeFragment class.`

Build error:

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0234	The type or namespace name 'Mvc' does not exist in the namespace 'Microsoft.AspNetCore' (are you missing an assembly reference?)	appFileManager.Blazor	C:\temp\....\Blazor.MvcApplicationPartsAssemblyInfo.cs	14	Active

This code isn't generated by CSLA, it is being generated by ASP.NET (that is my guess anyway).

I suspect you are missing an assembly reference to Microsoft.AspNetCore.

Hi Rocky,

I've added the nuget package Microsoft.AspNetCore but still get this error.

I already searched online for the class ApplicationPartAttribute and found:
https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.applicationparts.applicationpartattribute?view=aspnetcore-5.0

I added nuget package Microsoft.AspNetCore.App.Ref, this didn't solve the problem. I get this error after installing the package, so I removed it.
Severity Code Description Project File Line Suppression State
Error NU1213 The package Microsoft.AspNetCore.App.Ref 5.0.0 has a package type DotnetPlatform that is incompatible with this project. Parrow.Blazor E:\Gits.Git.Projects\Idas\PROTOTYPE-ABP43\src\Parrow.Blazor\Parrow.Blazor.csproj 1

I added nuget package Microsoft.AspNetCore .Mvc and (later) Microsoft.AspNetCore.Mvc.Core but that made no difference. So I removed these packages.

Then I found this link:

dotnet/aspnetcore#26724 and subsequently dotnet/aspnetcore#24171 which suggest adding:

false

to the project properties. That seems to do the trick !
