c# - How to use EntityFramework CodeFirstStoreFunctions nuget package? -

i trying access existing function in db. want execute function code first.

searching net found:

https://codefirstfunctions.codeplex.com/

my implementation of this:

protected override void onmodelcreating(dbmodelbuilder modelbuilder) {     modelbuilder.entity<trainmessage>()         .property(e => e.latitude)         .hasprecision(18, 16);      modelbuilder.entity<trainmessage>()         .property(e => e.longitude)         .hasprecision(18, 16);      modelbuilder.entity<stop>()         .property(e => e.stop_lat)         .hasprecision(18, 16);      modelbuilder.entity<stop>()         .property(e => e.stop_lon)         .hasprecision(18, 16);      modelbuilder.entity<order>()         .property(e => e.latitude)         .hasprecision(18, 16);      modelbuilder.entity<order>()         .property(e => e.longitude)         .hasprecision(18, 16);      modelbuilder.entity<subscription>()         .property(e => e.starttime)         .hasprecision(0);      modelbuilder.entity<subscription>()         .property(e => e.endtime)         .hasprecision(0);      modelbuilder.entity<orderlocation>()         .property(e => e.latitude)         .hasprecision(18, 16);      modelbuilder.entity<orderlocation>()         .property(e => e.longitude)         .hasprecision(18, 16);      modelbuilder.entity<order>()         .hasmany(e => e.orderlocations)         .withoptional(e => e.order)         .hasforeignkey(e => e.order_id);      modelbuilder.conventions.add(new functionsconvention<transitcontext>("dbo")); }  [dbfunction("transitcontext", "tvf_getallstopsinbetween")] public iqueryable<int> getallstopsbetweenstations(int stopa_id, int stopb_id) {    var = new objectparameter("stopa_id", stopa_id);    var b = new objectparameter("stopb_id", stopb_id);      return ((iobjectcontextadapter)this).objectcontext         .createquery<int>("[dbo.tvf_getallstopsinbetween](@stopa_id, stopb_id)", a, b);   } 

it not show in guide have function in db , create in code figure not need rest of code.

i have 2 problems this

1) no matter data trying db get:

the argument 'name' cannot null, empty or contain white space.

2) when remove part of code:

modelbuilder.conventions.add(new functionsconvention<transitcontext>("dbo")); 

i this:

errordescription = "'dbo.tvf_getallstopsinbetween' cannot resolved valid type or function."

message = "'dbo.tvf_getallstopsinbetween' cannot resolved valid type or function. near escaped identifier, line 1, column 1."

i new codefirst , inherited code.

how solve this?

i got

the argument 'name' cannot null, empty or contain white space.

when using nuget package.

i cloned codeplex repo , used source directly , error went away. think nuget out of date
