ASP.NET Core 3 and 500.30 In-Process Startup Failure
My service targets the following frameworks:
- Microsoft.AspNetCore.App 3.0.0
- Microsoft.NETCore.App 3.0.0
Everything runs fine locally. When I deploy to an App Service in Azure, I experience the following error:
500.30 In-Process Startup Failure
Reading the documentation tells me perhaps these frameworks are not on the machine hosting my service. However I checked what frameworks are installed on the machine by running dotnet --info on the App Service's console, giving me the following results:

To install additional .NET Core runtimes or SDKs:

Clearly both my targeted frameworks exist on the machine.
Here is (partial) proof my files are deployed:
Here is my start up file (nothing unusual):
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddCors();
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseCors();
app.UseRouting();
app.UseEndpoints(endpoints => {
endpoints.MapControllers();
});
}
}
What am I doing wrong? Why am I getting this error?
