Question: I had my PC re-imaged for me. I have Visual Studio Version 14.0.25123.00 Update 2 installed on my computer. I'm getting this error when I try to use VS intellisense to reference another project.

I have two projects. One of them using namespace `ProjectName.Web`. And the other project using `ProjectName.Web.Controllers`. The provider crashes when I reference `ProjectName.Web.Controllers`, I believe because it is setup as a project. Any idea how to fix this?

Answer: 
I end up with this same error.
what i did was to manually go and find the nuget packet for System.Data.SqlClient, installed and then invoke it in the class i was working on, like: 

```
using System.Data.SqlClient;

```

Dont know if this is some kind of bug, cause it happens on a new blank project i create using visual studio 2019 community

hope it helps someone
anyone trying this solution from here ?

the last reply solves my issue..

`Tools` > `Options` > `Text Editor` > `C#` > `Advanced`

turning off `Suggest usings for types in NuGet packages`
