EntityCommandExecutionException with EF5

Post by tco95ttocs » Tue 07 May 2019 06:18

Hi guys,

i got a problem selecting some data from my postgres-DB

When i do i got an exception:
NetTopologySuite spatial service provider value checking failed. Unexpected provider value type 'Microsoft.SqlServer.Types.SqlGeometry'.
first of all i try to create a point-geometry:

Code: Select all

var bm_dop = DbGeometry.FromText("Point(" + x_coord_bm_dop + " " + y_coord_bm_dop + ")", 25832);
this all works fine. Now i try to get some data from another table using the point-geometry with the distance-method

Code: Select all

var bildvorhanden = db.bild.Where(x => x.bildflug_id == bildflug && x.ausgefloeht == false).OrderBy(x => x.bildmitte.Distance(bm_dop)).First();
Here i got the above error! Why?

i use the folowing things:

EF 5
dotconnect 7.13.1366.0
Postgis 1.5.8
Postgres 9.1.5
Nettopologysuite 1.13.2

in my App.config i have the following entrys:

Code: Select all

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="Devart.Data.PostgreSql.Entity" type="Devart.Data.PostgreSql.Entity.Configuration.PgSqlEntityProviderConfigurationSection, Devart.Data.PostgreSql.Entity.EF5, Version=7.13.1366.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />

    </DbProviderFactories>
  </system.data>
  <Devart.Data.PostgreSql.Entity xmlns="http://devart.com/schemas/Devart.Data.PostgreSql.Entity/1.0">
    <SpatialOptions SpatialServiceType="NetTopologySuite" />
  </Devart.Data.PostgreSql.Entity> 
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
      <assemblyIdentity name="NetTopologySuite" publicKeyToken="f580a05016ebada1" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-1.13.3.0" newVersion="1.13.3.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
  </configuration>
So what could be wrong?

Thx for helping

Please upload a small test project with the corresponding DDL/DML script for reproducing the error to some file exchange server to some file exchange server (e.g.: www.dropbox.com) and send us the download link.
