Running .NET Framework 4.8 Projects with IIS Express and the SDK Project Format
Using IIS Express with .NET Framework 4.8 projects can be a bit tricky, especially when you're working with the newer SDK-style .csproj files. This article will guide you through the process and shed light on the nuances involved.
The Challenge: .NET Framework 4.8 and the SDK Format
The .NET Framework 4.8 and the SDK format are not always compatible. The SDK format is primarily designed for .NET Core and .NET 5+, while traditional .NET Framework projects often utilize older project formats. This difference can lead to confusion when attempting to use IIS Express with a .NET Framework project using the SDK format.
Scenario and Original Code:
Let's imagine you have a classic ASP.NET Web Forms project targeting .NET Framework 4.8. You've recently migrated your project to the SDK format, and now you want to run it with IIS Express. The typical approach might involve adding the following code to your .csproj file:
<PropertyGroup>
<TargetFramework>net48</TargetFramework>
<OutputType>Exe</OutputType>
<UseIISExpress>true</UseIISExpress>
<IISExpressSSLPort>44349</IISExpressSSLPort>
<IISExpressAnonymousAuthentication>enabled</IISExpressAnonymousAuthentication>
</PropertyGroup>
Unfortunately, this won't work as expected with .NET Framework 4.8 and the SDK project format. You'll likely encounter errors regarding missing dependencies or configuration issues.
Understanding the Problem:
The issue lies in the compatibility gap between the SDK format, designed for newer .NET versions, and the traditional .NET Framework 4.8. IIS Express configurations are often designed to work seamlessly with .NET Core and later frameworks, which have different dependency structures and build processes compared to the .NET Framework.
The Solution: Leverage the MSBuild Framework and Configuration Files
To overcome this hurdle, you need to leverage the power of the MSBuild framework and manually configure your project to work with IIS Express.
Here's a detailed approach:
-
Create a Custom Target in your
.csproj:<Target Name="AfterBuild" AfterTargets="AfterBuild"> <Exec Command=""$(MSBuildProjectDirectory)\$(TargetFramework)\tools\webdev.cmd" /project:$(MSBuildProjectFullPath) /port:44349" /> </Target>- Explanation: This target runs a command after the build process completes. The command executes
webdev.cmd(usually found in the .NET Framework folder) with parameters to launch IIS Express for your project. You can customize the port number (/port:44349) to your preference.

-
Configure the
web.configfile:- In your
web.configfile, ensure you have appropriate configurations for your IIS Express setup. This includes settings for authentication, authorization, and other relevant aspects. Refer to MSDN documentation for details.
- In your
-
Set Up the Correct Project Configuration:
- In your
csprojfile, specify theTargetFrameworkasnet48.
- In your
Additional Tips:
- Use a Visual Studio Extension: Consider using the Visual Studio extension "IIS Express for .NET Framework" from the Visual Studio Marketplace. This extension provides a user-friendly way to launch IIS Express for .NET Framework projects.
- Update the
webdev.cmdPath: If thewebdev.cmdfile is not in the expected location, you may need to adjust the path in your.csprojfile.
Summary:
Running .NET Framework 4.8 projects with IIS Express in the SDK format requires careful consideration of compatibility and configuration. By using custom targets, configuring the web.config file, and adjusting the project configuration, you can successfully launch your project in IIS Express. Remember to consult the official documentation for detailed instructions and specific configurations related to your particular project.
