🕵️‍♀️ Understanding the Problem

The error message you're seeing indicates that there is an issue with the security permissions in your project. Specifically, a method called PreApplicationStartCode.Start() from the WebMatrix.WebData namespace is trying to access a method called AddGlobalImport() from the System.Web.WebPages.Razor.WebPageRazorHost class. However, it's failing to do so due to security restrictions.

ℹ️ Note: The exact cause of this error can vary depending on the specific conditions of your project. However, the general steps outlined in this guide should help you resolve the issue.

💡 Easy Solution: Modifying Web.config

One simple solution that often resolves this error is modifying the Web.config file in your project. Follow these steps:

1. Open the Web.config file in your project.

2. Look for the <httpModules> section.

3. Remove the following line: <add name="WebMatrix.WebData.PreApplicationStartCode" type="WebMatrix.WebData.PreApplicationStartCode" />.

4. Save the Web.config file.

Now, try running your application again. In most cases, this modification should resolve the "Attempt by security transparent method..." error, and you'll be able to continue developing without any issues.

🔍 Deeper Dive Solution: NuGet Package Conflicts

If the above solution didn't fix the problem, it's possible that you have some conflicts between NuGet packages in your project. Here's how you can tackle this situation:

1. Open your NuGet Package Manager.

2. Go to the "Installed" tab and look for packages related to WebMatrix or System.Web.WebPages.Razor.

3. Update all relevant packages to their latest versions.

4. Clean and rebuild your solution.
