'Microsoft.SqlServer.Types' version 10 or higher could not be found on Azure
asp.net MvcEntity FrameworkAzureasp.net Mvc Problem Overview
I'm trying to make a webapi in ASP.NET MVC 4. The webapi used Entity Framework 5 Spatial types and i have wrote a very simple code.
public List<Area> GetAllAreas()
{
List<Area> aList = db.Areas.ToList();
return aList;
}
Area contains DbGeometry.
When i run this local it works, but when i publish it to azure it gives me this 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.
Anyone know how to resolve this ? :)
Thanks!

I found the solution ! Just install the nuget package Microsoft.SqlServer.Types
> PM> Install-Package Microsoft.SqlServer.Types
Solution 2 - asp.net Mvc
The answer above works fine when version 11 (SQL Server 2012) of the assembly can be used.
I had a problem with this as my solution has other dependencies on version 13 (SQL Server 2016) of the same assembly. In this case note that Entity Framework (at least v6.1.3) is hardcoded in its SqlTypesAssemblyLoader (the source of this exception) to only look for versions 10 and 11 of the assembly.
To work around this I discovered you can tell Entity Framework which assembly you want to use like this:
SqlProviderServices.SqlServerTypesAssemblyName = typeof(SqlGeography).Assembly.FullName;
Solution 3 - asp.net Mvc
For some reason I was missing a binding redirect which fixed this problem for me.
Adding the following fixed my problem
<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>

There are 2 ways to fix that:
-
If you have server access, just Install “Microsoft System CLR Types for SQL Server 2012” it’s from https://www.microsoft.com/en-us/download/details.aspx?id=29065 Or Use Direct Link Below Direct Link to X86 :http://go.microsoft.com/fwlink/?LinkID=239643&clcid=0x409 , Or Direct Link to X64 :http://go.microsoft.com/fwlink/?LinkID=239644&clcid=0x409
-
Second way is to use NuGet package manager and install
Install-Package Microsoft.SqlServer.Types
Then follow the plugin notes as below

Solution 5 - asp.net Mvc
Please add "dependentAssembly" the Web.config file
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<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>
</assemblyBinding>
</runtime>
This worked for me
Solution 6 - asp.net Mvc
I also encountered this problem, but the Microsoft.SqlServer.Types nuget package was already installed.
What solved the problem for me was going to Solution > References > System.Data.Entity > Properties > Copy Local, and setting it to True.
Note: Copy Local for Microsoft.SqlServer.Types was already set to true, and even though the problem was with System.Data.Entity, the error message was still about Microsoft.SqlServer.Types.
The solution is from Windows Azure forum.
Solution 7 - asp.net Mvc
The solution for me was just adding this line of code to Global.asax.cs in Application_Start()
:
SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("~/bin"));
Good luck my brothers.
Solution 8 - asp.net Mvc
Following a comment in an answer for current post, adding these two lines (preferebly to the main function) solved my problem for Console App:
SqlProviderServices.SqlServerTypesAssemblyName = typeof(SqlGeography).Assembly.FullName;
SqlServerTypes.Utilities.LoadNativeAssemblies(AppDomain.CurrentDomain.BaseDirectory);
Solution 9 - asp.net Mvc
In my case (a WebForms App) I solved the problem adding the following lines in the Application_Start
of the Global.asax
file.
SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("~/bin"));
System.Data.Entity.SqlServer.SqlProviderServices.SqlServerTypesAssemblyName = "Microsoft.SqlServer.Types, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91";
I hope it helps someone.
Solution 10 - asp.net Mvc
None of the above solutions worked me.
- SQL Server Feature pack installed? Yes
- NuGet package installed? Yes
- DLL exists in GAC and in the project bin? Yes
You know what, this error can also be due to low resources on the server. I restarted SQL server and it got resolved automatically.
Solution 11 - asp.net Mvc
Just had the same issue. I am using EF6
and calling SQL
which has a SQL function that uses spatial commands. I tested this through a unit test and it worked fine. When I went to wire up my Asp.Net
solution I received the 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.
By adding the NUGET
package "Microsoft.SqlServer.Types" and adding SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("~/bin"));
to the Application_Start method
in Global.asax.cs
everything worked fine.

In my case, a badly composed connection string caused this. Verify if your connection string is properly composed.
