User defined stored procedure - where's the execution plan?

SQL Server 2016, Enterprise Edition in Windows Is there anyway to display the execution plan of a stored procedure created in C# with Visual Studio Data Tools? This is a question that someone with Visual Studio experience probably knows the answer to. My searches on Google haven't turned up anything useful. Here is the stored procedure in c# using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; public partial class StoredProcedures { [Microsoft.SqlServer.Server.SqlProcedure] static public void Addition (SqlInt32 a1, SqlInt32 a2, out SqlInt32 sum) { sum = a1 + a2; } } Here is the execution in SSMS 2017 v17.3 USE CLR1; declare @sum int exec dbo.Addition 3, 4, @sum output select @sum I have also been able to find the execution plan in cache. Even though there is a plan_handle available in dm_exec_procedure_stats, I can't seem to use a cross apply to [dm_exec_query_plan] to view it.
