So, why not write a blog post about it!</p> <p>When running EF Core migrations in a solution, you may come across this error:</p> <p><a href="https://rnemeth90.github.io/wp-content/uploads/2022/06/image-1-1024x142.png" class="external-link" target="_blank" rel="noopener"></a></p> <p>There are several apparent causes. However, in my case (every time I have seen this), it has been caused by having multiple startup projects selected in Visual Studio.</p> <p>To fix this, simply open your Solution properties and set the startup project to ‘Current Selection’.</p>
