Operating System: windows

Provide details about the problem you're experiencing. Include your operating system version, exact error message, code sample, and anything else that is relevant.

When I copied the code a red squiggly line under [Parameter] appeared saying "The type or namespace name 'Parameter' could not be found (are you missing a using directive or an assembly reference?) [Final-Project-OOP-TheRealDeLorian]csharp(CS0246)"

@mairaw Can you please help? Maybe the tutorials are missing adding some using directive.

@TheRealDeLorian can you paste the contents of the files you modified to see if they match what we have on the site?

​Here is the code inside my pages/Counter.razor file

@page ​"​/counter​"

​<​PageTitle​>Counter</​PageTitle​>

​<​h1​>Counter</​h1​>

​<​p​>Current count: ​@currentCount​</​p​>

​<​button​ ​class​=​"​btn btn-primary​"​ ​@OnClick​=​"​IncrementCount​"​>Click me</​button​>

​@code​ ​{
​    ​private​ ​int​ ​currentCount​ ​=​ ​0​;

​    [​Parameter​]
​    ​public​ ​int​ ​IncrementBy​ ​{​ ​get​; ​set​; ​}​ ​=​ ​5​;

​    ​private​ ​void​ ​IncrementCount​()
​    {
​        ​currentCount​+=​IncrementBy​;
​    }
​}

So I opened my project today and for some strange reason the error is not showing up, so problem solved. Thanks for being willing to help, you guys are always so supportive.
