Question
I saw a few questions related to this on stack overflow but none of them helped. I am using VS 2019 community edition, I created an API project on .NetCore 2.1, and added the following nuget packages. (assuming all EF packages will be included by default)
Microsoft.EntityFrameworkCore.SqlServer
Microsoft.EntityFrameworkCore.Design
After some time into the coding I needed to use MapToStoredProcedures in the OnModelCreating function..But its not available,
entitytypebuilder doesnot contain a definition for maptostoredprocedures
after looking for a few solutions, i tried to
install-package Microsoft.EntityFrameworkCore.Relational
which did not work as there was a version conflict issue...
NU1202: Package Microsoft.EntityFrameworkCore.Relational 3.0.0 is not compatible with netcoreapp2.1 (.NETCoreApp,Version=v2.1).
then i tried to install SDK and restart VS, then i again tried to install Microsoft.EntityFrameworkCore.Relational nuget package but the same error was there.
Finally, I installed:
Microsoft.EntityFramework (6.3) and an older version of Microsoft.EntityFrameworkCore.Relational (2.1.11)
which was successful but the MapToStoredProcedures function is still unavailable.
the using statement in the class also doesnt show Microsoft.EntityFrameworkCore.Relational namespace...
I am very confused as this function used to be available in VS 2013 with EF 6. :S
Accepted Answer
So i realize that EF 6 used to have the MapToStoredProcedures function and EF Core doesn't have it. (Not sure why they decided like that).
I changed my target framework to netcoreapp3.0 from netcoreapp2.1 and then i was able to install Tools and Microsoft.EntityFrameworkCore.Relational packages.
Finally, I am calling my sp as follows:
var dbResults = _gecontext.ParameterDetails.FromSqlRaw("EXEC dbo.get_nextParamSummary @UserId={0}", userId).ToList();
