Assembly 'Microsoft.SqlServer.Types' version 10 or higher could not be found

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 this provider because the assembly 'Microsoft.SqlServer.Types' version 10 or higher could not be found."

I know there are several questions and answers about this, like:

• 'Microsoft.SqlServer.Types' version 10 or higher could not be found on Azure
• "Spatial types and functions are not available" error when converting a string to DbGeometry in ASP.NET

But! The problem is...

• I already have installed Microsoft.SqlServer.Types.
• I already have Global.asax configured with: SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("~/bin")) into the Application_Start.
• Reference is set to local copy > true.
• NuGet packages are all updated.
• I already try to downgrade and upgrade the package.

This is the full error when I try to run for example Add-Migration v002:

System.InvalidOperationException: Spatial types and functions are not available for this provider because the assembly 'Microsoft.SqlServer.Types' version 10 or higher could not be found.

Answer 1

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>

Answer 2

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 3

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 4

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!
