Why are particular dll's deleted from Azure App Server site when deploying? - azure

Question

I have a .net app that I deploy to Azure. It is compiled to the directory c:\publish\bin under Release compile option, but for some reason it deletes one dll in particular , the System.Runtime.dll.
So before it starts to deploy it displays this
Starting Web deployment task from source:
manifest(C:\LocalWebProject\obj\Release\Package\My.SourceManifest.xml) to Destination:
auto(). Deleting file (AzureAppService\bin\System.Runtime.dll).
Adding ACLs for path (MyWebProject)
Any ideas why this would happen ?

Particular dll's deleted from Azure App Server site when deploying:
I've created a sample webapp using visual studio and was able to deploy it successfully to Azure.
Program.cs:
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddRazorPages();
var app = builder.Build();
if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.MapRazorPages();
app.Run();
appsettings.json:
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Warning"
}
},
"AllowedHosts": "*"
}
Build on IIS Server:
Published to Azure:
Output:
Need to check:-
Never put anything in bin. Bin is not a source folder for binaries rather, it is the destination location for binaries.
Dependency Tree
.CsProj
|
classlibrary.dll
|
.binlibrary.dll
It is preferable to think of the bin folder as it is created by a project as "output" directory; they should only contain files generated by the project build.
Instead of using build, try rebuild which will perform cleanup and build the current project. Usually, the outputs from previous builds are kept with the build command. Therefore, it may result these kinds of dependency related actions like "deletion of specific dll files". Rebuild does remove them and build again.
While cleaning up, it might remove the necessary dependencies also. It is possible to restore deleting files.
Note:
I suggest, Use Visual studio while working with Web Apps to avoid these kinds of issues.
Check for Visual Studio version and update it to latest versions.
