A compatible SDK version for global.json version : [2.1.500] from [project directory\global.json] was not found
Did you mean to run dotnet SDK commands? Please install dotnet SDK from: url
* **What is the expected behavior?**
.Net SDK 2.2.105 is installed
created empty web project in VS2017 (Tried an ASP .NET MVC template as well. same issue)
Ran from CLI: au new --here

4 - Typescript
5 - Default
6 - default
7 - default
8 - default

Current directoy is not empty Create in this folder? Yes
Install Project dependencies? Yes
Error occurs at the end of dependency installation along with 1 high severity vulnerability. au run will serve the project to local host 5000

* **What is the motivation / use case for changing the behavior?**

Installation should occur with no errors and no vulnerability issues.

Reproduce the issue with `au new --here` in the described ASP.NET Core project setup and the `global.json` containing SDK version 2.1.500. Inspect the CLI's ASP.NET Core project-generation and dependency-installation path; done means dependency installation completes without the SDK compatibility error, while verifying the reported vulnerability separately.
