Breakpoints wont hit in blazor webassembly project asp net core 3 1

Introduction

ASP.NET is a popular programming language used for building web applications. It provides a framework for developing websites, web services, and web applications. One common issue that developers face working with ASP.NET is breakpoints not hitting in Blazor WebAssembly projects with ASP.NET Core 3.1. In this article, we will explore the possible solutions to this problem.

Understanding the Issue

When breakpoints don't hit in a Blazor WebAssembly with ASP.NET Core 3.1, it can be frustrating for developers as it hinders the . Breakpoints are essential for identifying and fixing issues in the code. However, there are a few reasons why breakpoints may not hit in this scenario.

Possible Solutions

1. Check Debug Configuration

The first step is to ensure that the project is configured for debugging. Open the project properties and navigate to the “Build” tab. Make sure that the “Debug” configuration is selected. If it is not, it and rebuild the project.


// Example code
public void ConfigureServices(IServiceCollection services)
{
    // Configure services here
}

2. Enable Debugging in Launch Settings

possible solution is to check the launchSettings.json file in the project. Open the file and ensure that the “launchBrowser” and “inspectUri” properties are set to true. This enables debugging in the browser and allows breakpoints to hit.


// Example code
{
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}"
    }
  }
}

3. Check for Compilation Errors

Compilation errors can prevent breakpoints from hitting. Make sure that there are no compilation errors in the project. Check the error list and any issues before to debug the code.

4. Clean and Rebuild the Project

Sometimes, cleaning and rebuilding the project can resolve issues with breakpoints not hitting. Right- on the project in Visual Studio and select “Clean”. Once the cleaning process is complete, right-click again and select “Rebuild”. This will rebuild the project and may fix the breakpoint issue.

5. Disable Optimization

Optimization settings can sometimes interfere with breakpoints. To disable optimization, open the project properties and navigate to the “Build” tab. Under the “Advanced” section, set the “Debugging information” dropdown to “Full”. This ensures that the code is not optimized and allows breakpoints to hit.


// Example code
public void ConfigureServices(IServiceCollection services)
{
    // Configure services here
}

Conclusion

Breakpoints not hitting in Blazor WebAssembly projects with ASP.NET Core 3.1 can be frustrating, but with the right approach, it can be resolved. By checking the debug configuration, enabling debugging in launch settings, resolving compilation errors, cleaning and rebuilding the project, and disabling optimization, developers can ensure that breakpoints hit and facilitate the debugging process.
