<t>I use Visual Studio 2017 and create a new ASP.NET Core project.<br/>
I add migration for Entity Framework Core as below<br/>
<br/>
add-migration "Initial Create"<br/>
<br/>
```<br/>
<br/>
and get the following error:<br/>
<br/>
```<br/>
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework\Add-Migration' for Entity Framework 6.<br/>
Build Failed.<br/>
<br/>
```<br/>
<br/>
Do you know how to resolve this error?<br/>
<br/>
## **UPDATE 1 - March 14, 2017 - Result received after running command**<br/>
<br/>
```<br/>
PM> dotnet ef migrations add "Initial Create"<br/>
<br/>
```<br/>
<br/>
**I see the following output with error message at the end.**<br/>
<br/>
```<br/>

Telemetry<br/>
--------------<br/>
The .NET Core tools collect usage data in order to improve your experience. The data is anonymous and does not include command-line arguments. The<br/>
data is collected by Microsoft and shared with the community.<br/>
You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.<br/>
