Frequently Asked Questions
Stuck in Visual Studio 2019 and can’t find those pesky references? Don’t worry, we’ve got you covered!
Why can’t I find references in my Visual Studio 2019 project?
This might happen if your project is not set up to use the correct framework or platform. Try checking your project properties to ensure that the target framework and platform are correct. Also, make sure that the referenced assembly is compatible with your project’s framework.
I’ve checked my project properties, but I still can’t find the references. What’s next?
Hmm, that’s weird! In that case, try cleaning and rebuilding your project. Sometimes, Visual Studio just needs a little kick in the pants to get things working again. Go to Build > Clean Solution, and then Build > Rebuild Solution. If that doesn’t work, try deleting the .suo and .csproj.user files and then reopening your project.
I’ve tried cleaning and rebuilding, but I still can’t find the references. What about my NuGet packages?
Aha! Good thinking! NuGet packages can sometimes cause issues with references. Try updating all your NuGet packages to the latest version, or try removing and reinstalling the problematic package. You can also try deleting the package cache and then reinstalling the package.
I’ve checked everything, but I still can’t find the references. Is it a Visual Studio bug?
It’s possible, but unlikely. Before you blame Visual Studio, try resetting your Visual Studio settings to their default values. Sometimes, a wonky setting can cause issues. You can also try reinstalling Visual Studio or seeking help from the Visual Studio community forums.
I’ve tried everything, and I still can’t find the references. What’s the last resort?
Okay, last resort time! If all else fails, try creating a new project from scratch and adding your files one by one. This might help you identify if the issue is with a specific file or dependency. If that still doesn’t work, you might need to seek help from a seasoned developer or a Visual Studio expert.
