After change extension from .Net 3.5 to .Net 4.0 Debugging is no more possible

LionelMartz — Tue, 18 Jan 2011 13:12:18 GMT

Hello everyone,

I have a strange problem trying to debug an extension.

We are developping an ArcGIS-Extension. It used to be a .Net 3.5 Project for ArcView 9.3.
Now, we want to update this extension to the .Net Framework 4.0 on ArcGIS 10.
First, we made it work for ArcGIS 10 without any problems following the guide vom ESRI.
We also can change the version of the framework in Visual Studio 2010 from 3.5 to .Net 4.0.

After this change, wie can still compile the extension and start ArcMap in the VS debuggin mode properly. First we thougth that it worked. But then we tryed to debug this version. By setting a breakpoint in VS, is says:
"The break point currently will not be hit, no symbols have been loaded to this document".

Then we saw, our extension wasn't even registered to the Global Assembly Cash, however,
I don't know how this is possible, because it seemed to be startet properly with ArcMap.

Does anybody have an idea?

This is usually an indication that ArcMap is loading an older version of the dll. Try cleaning out the bin folder of your project, try searching and deleting any other dll with the same name on your machine.

I've had similar problems but was never able to fully sort it out before moving on to other tasks. I've noted that even when receiving that same message when setting breakpoints, the breakpoint is still hit when debugging, so you might want to give it a shot anyways.

Aside from clearing out the bin folder as the prior poster suggests, you might also want to edit ArcMap.exe.config. Find

<supportedRuntime version="v2.0.50727"/>

And add

<supportedRuntime version="v4.0"/>

Some users have had success with this, from what I've been able to gather reading the forums. In my case, ArcMap simply opens and closes.

Please let us know if you are able to solve the issue.

Thank you for the fast answers.

The idea, the breakpoint could work anyway was good - I never tryed, but unfortunately it didn't worked.

I know the problem with other versions of Dlls. To assure that isn't the problem, I verified the version of the running extension, and its allways like the version I'm compiling. After cleaning the Project, no extension was loaded anymore by starting ArcMap

I now tryed to manipulate the ArcMap.exe.config without success.

What I really don't understand is: I can attach a process to Visual Studio. That shows me the loaded Modules(dlls). Our extension is not listet, while it is compiled für .NET 4.0.

Thanks anyway
Lionel

Edit: I forgot to mention, I already modified the ESRIRegAsm.exe.config adding <supportedRuntime version="v4.0"/>
When I register the DLL in the Shell with the ESRIRegAsm.exe the system tells me the registration was successful.

If your extension is longer showing up in ArcMap, it is no longer registered and the one loading before was an old one. When running arcmap, can you load the tlb manually? If so your dll is fine just the registration is not being done. If not, there is some other problem.

That's the point. The extension is shown-up in ArcMap, even in the newest version. It works, but the extension.DLL is not loaded with ArcMap. I don't know how that works, but it does.

When I compile in .Net 3.5 I can do this:
1. Register the DLL
2. Start ArcMAP
3. Attach the ArcMap process to Visual studio
4. Open the List of the running modules of ArcMap
5. Thas shows me my "extension".dll

Now I Can stop ArcMap, unregister the extension, restart arcMap, an no extension is loaded anymore.

When I comile in .Net 4.0 everything it's the same, except of point 5. My "extension".Dll is NOT listet within the modules, but works fine with ArcMap. After unregistering this DLL, ArcMap starts without the extension.

So, ArcGIS 10 SDK doesn't support .NET 4.0 yet. Does someome know, if support could come sometime ?

Did you change the ArcMap.exe.config to allow you to debug against .NET 4? The default behavior prior to 10.4 is for it to only allow debugging against 3.5. The url below explains how to do this. It says 10.2 in the title, but it should be true for 10.0 to 10.3.1.

Hi freddie,

Thanks for the reply.

I am using Nunit version 2.6.4 to debug the code.

Its working fine with .net framework 3.5 but as i upgrade the version to 4.0 after that breakpoint not get hit due to that debugging is no more possible.

Did you update your arcmap.exe.config file? Or could you upload it here?

What version of ArcGIS Desktop are you using? What application are you needing to debug in? (e.g. ArcMap, ArcCatalog, ArcScene, ArcGlobe) What version of VS are you using?

The exe.config file should start like on of the following:

Version 10.0 - 10.3 should start as follows

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0.30319"/>
    <!--<supportedRuntime version="v2.0.50727"/>-->
  </startup>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="ESRI.ArcGIS.ADF.Local" culture="" publicKeyToken="8fc3cc631e44ad86"/>
        <bindingRedirect oldVersion="9.3.0.0-10.2.0.0" newVersion="10.3.0.0"/>
      </dependentAssembly>
    </assemblyBinding>‍‍‍‍‍‍‍‍‍‍‍‍‍

Version 10.4 and higher (Note 10.4 uses .NET 4 as the Minimum Version) should start as follows

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
  </startup>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="ESRI.ArcGIS.ADF.Local" culture="" publicKeyToken="8fc3cc631e44ad86"/>
        <bindingRedirect oldVersion="9.3.0.0-10.3.0.0" newVersion="10.4.0.0"/>
      </dependentAssembly>
    </assemblyBinding>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks for the reply.

I added this code of line in nunit.exe.config file and now the breakpoint started hitting.

so the issue get resolved.
