问题
I just started trying out the mvc-mini-profiler in my MVC3 project with EF4.1 and after changing MiniProfilerEF.Initialize(); to MiniProfilerEF.Initialize_EF42(); I'm getting :
A null was returned after calling the 'GetService' method on a store provider instance of type 'MvcMiniProfiler.Data.EFProfiledOdbcProviderFactory'. The store provider might not be functioning correctly.
This method MiniProfilerEF.Initialize(); - was giving me
The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
So I've replaced dll's with ones I've manually built from the source.
What could be the problem in here ?
回答1:
If it helps, the EF team have release a beta preview with a fix for the error
The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
See http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-release-candidate-available.aspx
You can get it from Nuget using
PM> Install-Package EntityFramework.Preview
I just tested it on my build and it fixes the issue meaning you can just call MiniProfilerEF.Initialize(); as before instead of the new method.
回答2:
Please analyze what version of Entity Framework your application is using PM> Get-Package
and then install MiniProfiler.EF accordingly
Like in my case I installed Install-Package MiniProfiler.EF5
