IIS Express 调试时启动极慢

Question

I am working on a C# MVC project that is set up to run using IIS Express. I am using Rider as my IDE and every time i start the project using the "Run" option it starts up quickly without any issues. However, when starting the project using the "Debug" option the startup is extremely slow 95% of the time - and by extremely slow i mean up to 10 minutes. The build process itself is very quick and I have narrowed down the issue to IIS. I also tried running the project via Visual Studio with the same effect.

Some of the modules that are loaded by IIS load extremely slow - not always the same ones, but the usual culprits are:

FeatureToggle.dll
CsQuery.dll
System.Web.Http.OData.dll

I have read almost every single question relating to slow startups on google with no effect. I have tried reinstalling, changing configuration, clearing cache among others.

The issue has been here since I received the laptop. My co-workers are using the same laptops and have no issues at all.

Any help or suggestions are highly appreciated

Answer 1

I managed to solve it by following the instructions from this link

Some assemblies are signed with the Microsoft digital certificate and the delay occurs due to the runtime attempt to verify the certificate.

Add the following to your configuration file:

<configuration>  
    <runtime>  
        <generatePublisherEvidence enabled="false"/>  
    </runtime>  
</configuration> 

Hope this helps someone.
