Could not load assembly ESRI.ArcGIS.ADF.Connection.Local

[LAFOSSE_CATELAnnick]

Hi,


I have Console Application that I need to migrate from 9.3 to 10.1.
I have done :
- Changed framework 2.0 to 3.5
- Put the new reference of ArcGis in 10.1
- Compile with platform target "Any CPU"

The problem is when i execute my console application on windows server 2008
I have this error : "Could not load ESRI.ArcGIS.ADF.Connection.Local".

On my server ArcGIser 10.1 and ArcSDE 10.1 are installed.

Thanks for your help.

Compile with platform target "x86"

It doesn't work.
My server is in 64 bits , ArcGis Server and ArcSde are also in 64 bits.

Should I register the ESRI.ArcGIS.ADF.Connection.Local ?

Thanks for your help

There is nothing to register because this is .NET.

This is a partial listing of what I get on my machine:

Directory of C:\Windows\assembly\GAC_32

09/14/2012  01:42 PM    <DIR>          ESRI.ArcGIS.ADF
09/14/2012  01:42 PM    <DIR>          ESRI.ArcGIS.ADF.Connection
09/14/2012  01:42 PM    <DIR>          ESRI.ArcGIS.ADF.Connection.Local

Any assembly in GAC_32 can only be used in a 32 bit application.  If you want to call this assembly then your host process has to be x86.

Thanks for your response.
It helps me a little.

In my directory c:\windows\assembly, i have only

"ESRI.ArcGis.ADF.Local" (version 10.1.0.30.35)

So it is logical that my assembly ESRI.ArcGis.ADF.Connection.Local could not be loaded.

What do I forget ? Why ESRI.ArcGis.ADF.Connection is not present ?

[RichardWatson]

A while back, I put together a file which contains a list of the assemblies which are installed by server.

See attached file.  What it says is that the assembly you seek comes with the web adaptor.

[LAFOSSE_CATELAnnick]

I have installed ArcGisWeb Adaptort (Web IIS) but i have still the same error "Could not load assembly ESRI.arcGis.ADF.Connection.Local "

It happens when i call "ComReleaser.ReleaseCOMObject()".

[RichardWatson]

Validate that the referenced assembly is on your machine.

Validate that the process that you are calling this from is 32 bit.

[LAFOSSE_CATELAnnick]

The assembly is not on my server (although i have installed ArcGis Web Adpator (II

My console application is compiled in "Any CPU".
If I compile in 32bits, the licence initializer fails.

You cannot use this assembly in a 64 bit process.

This is a very fundamental point that cannot be changed.

Desktop is 32 bit and Server is 64 bit.  That means that you can only use a desktop license in a 32 bit process and you can only use a server license in a 64 bit process.  You have to choose.

If you choose 64 bit then you need to grab a server license.  In this case you cannot use any assembly in GAC_32. If the assembly has something that you really need then you can either write it yourself or reflect it out using a tool such as Reflector. 

I suspect that you are heading down the wrong path here.
