Question

I Have a problem. I\'m not able to add a Migration to my ASP.NET WebAPI 2 Project. I get error:

\"Spatial types and functions are not available for t

Answer 1

After a lot of research I just installed "Microsoft System CLR Types for SQL Server 2012" from:

• X86 - http://go.microsoft.com/fwlink/?LinkID=239643&clcid=0x409
• X64 - http://go.microsoft.com/fwlink/?LinkID=239644&clcid=0x409

Worked like a charm!

Answer 2

the problem may be "virtual". You need to have SqlServerSpatial140.dll in bin folder at the moment you issue add-migration command. Just copy the .dll to bin for development purpose and replace manually the version (x86/x64) during deployment. Sql Server (2012+) already has the assembly installed.

Answer 3

Make sure you are not missing a binding redirect

  <dependentAssembly>
      <assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" culture="neutral" />
      <bindingRedirect oldVersion="10.0.0.0-11.0.0.0" newVersion="14.0.0.0" />
    </dependentAssembly>

Answer 4

This worked for me.

Add this to the web.config > system.webServer >> runtime >> assemblyBinding node

  <dependentAssembly>
    <assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-14.0.0.0" newVersion="14.0.0.0" />
  </dependentAssembly>
