Question

wondering if is possible to create xaml snippets
I have vs 2019,given I have created the below xaml snippet
Why is it when in visual studio xamarin project typing "grd" and tabbing nothing happens?
can somebody clarify whether the location and the snippet is correct?
Also what is the difference between codetemplate vs codesnippet?
Also if you any samples how todo in resharper that would be good too.

I followed this document and created a code snippet successfully, here are steps:
1.Create a new XML file in Visual Studio and add the code:
<?xml version="1.0" encoding="utf-8"?>
<CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">
<CodeSnippet Format="1.0.0">
<Header>
<Title>1213test</Title>
<Shortcut>grd</Shortcut>
</Header>
<Snippet>
<Code Language="XAML">
<![CDATA[<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
$selected$$end$
</Grid>]]>
</Code>
</Snippet>
</CodeSnippet>
</CodeSnippets>
2.Save the file with name MyCodeSnippet.snippet(not .xml).
3.Create a new project and go to Tools > Code Snippets Manager > import > find the MyCodeSnippet.snippet you just created > open > finish. (described here)
4.Open a xaml file and Type grd in the file and press Tab twice.(Note: twice), then it works.

Also what is the difference between codetemplate vs codesnippet
I did some research but can't any documentation about codetemplate.
