Visual Studio - Intellisense 无法识别同一解决方案中另一个项目中的命名空间

Question

I have a solution consisting of two projects.

The first project is Project.api, while the second is Project.models within C# .NET (webapi) solution. I can not get test.models to be recognized when pointing to it via using test.models; at the top of one of my classes.

What do I need to do to get the api project to not show red underline under the .models namespace?

I have tried to re assign asp.net version from 4.5.2 to 4.0, and included references to Project.models under Project.api without success.

How can I get past this intellisense issue?

Please see Solution Explorer screenshot. Root namespace renamed.

Answer 1

For anyone reading this in 2020, a fix that I've found that has worked for me is cleaning the solution and unloading the projects that have dependencies such as a web API depending on a data project and an application project, then reloading and building each project in the order of dependence such that they build successfully.

Unloading projects: right click on the project in solution explorer and find "Unload Project"

Reloading Projects: right click on the unloaded project in solution explorer and find "Reload Project"

so in my case my data project does not depend on any other project so I first reloaded and built that project, next the application project which depends on the data project and finally the web API project which depended on both data and application.
