New Post: Sharing IoC Containers Between Host and AddIns

resnik — Fri, 21 Nov 2008 14:42:28 GMT

Hi,
I have an application which uses Castle Windsor to register services that other modules of the application consume.
This application should now be extended with addins and I would like to share this container between the addins and the host, but I am a bit lost with all the views, adapters and interfaces.
For example, assume there is a contract IServiceContract and corresponding views IAddinService and IHostService. If the host registers a service like:

    
IWindsorContainer container = new WindsorContainer();
container.AddComponent<IHostservice,MyHostService>();

How would this service be consumed by the addin, since IHostService is not visible there?

Hi mSid & AddIn Team,

I wrote the below code in the host app.

AddInController

controller = AddInController.GetAddInController(addin);
AppDomain domain = controller.AppDomain;
domain.UnhandledException += new UnhandledExceptionEventHandler(domain_UnhandledException);

The host and the addin are in different AppDomains.
I have an unhandled exception in a AddIn which crashes the Host App.
The unhandled exception in addin never reaches host.

Whats the work around ?

Hi mSid,

Will the addInProcess.ShuttingDown Event fired when any unhandled exception occurs inside my AddInProcess ?

I had an unhandled exception inside my AddIn Process and the process went down. But the host has subscribed to this ShuttingDown event which was never called.

Any other way to detect an unhandled exception inside my AddInProcess so that i could know the process going down and i can start the AddInProcess again ?

Hi Mueez

Could you be more specific.
What do you mean by 'broker access'?

Currently I use the windows registry for simple types but have no solution for the rest.

Commented Issue: VS2008 SP1 br0ke my pipeline builder

agrahamatfes — Wed, 19 Nov 2008 20:39:41 GMT

I have been using pipeline builder for a while (normally I used Jan but I also tried feb and march). I run the normal calculator demo from daniel moths website without any issues... after installing VS2008 SP1, now when my addinview, etc gets created, the default application name is template? so now all my dll's are created as template.dll? Any sugestions on how to fix this?

New Post: Assembly name not being set by PipelineBuilder

agrahamatfes — Wed, 19 Nov 2008 20:18:42 GMT

I am unable to have Pipelinebuilder set the assembly names automatically. Even using the Common Pipeline Scenarios sample the assembly names of all of the generated projects is set to Template. Is this a known issue?

Bhupesh — Wed, 19 Nov 2008 06:01:53 GMT

I ams seeing a hang when i say

string path = Environment.CurrentDirectory;
string[] s = AddInStore.Update(path);

This is happening only in one machine.
The same code works fine in other machines.

Thanks,
Bhupesh.

mSid — Wed, 19 Nov 2008 00:30:08 GMT

Hi Bhupesh,

The intent of RebuildAddIns/UpdateAddIns is to look for add-in assemblies only (it doesn't look for any of the pipeline components). This is useful if you want to have add-ins stored in a separate location from the pipeline components.

Are you seeing a hang when calling it, or an unhandled exception? Can you provide details and a repro?

Thanks,

New Post: Cross AppDomain scoped static fields ?

mSid — Wed, 19 Nov 2008 00:24:42 GMT

Hi s_orbit,

You could use your host to broker access to the statics, and store them in the host's AppDomain. This way they are available to any add-in, regardless of how it's activated (it even works out of process). How does this sound?

Hi cln,

You could use the AddInProcess.ShuttingDown event, or use WaitForExit to detect if the add-in process goes down:
System.Diagnostics.Process.GetProcessById(addInProcess.ProcessId).WaitForExit();

New Post: Static Methods in my AddIn

Bhupesh — Tue, 18 Nov 2008 13:32:56 GMT

Hi All,

I want to expose a static method in my AddIn ? Is there a way ?
When i Activate the AddIn, i get the instance of the AddIn.

What's the work around in AddIns for static ?

New Post: VS Pipeline Builder Add-in not showing under Tools after SP1

Bhupesh — Fri, 14 Nov 2008 15:46:02 GMT

Infact you don't have to put all sources. Get the pipeline source code. Build it.
Just put the VSPipelineBuilder.AddIn file in AddIn's folder that is there in VSPipelineBuilder project.
Then open the VSPipelineBuilder.AddIn file and update the VSPipelineBuilder.dll path ( Path in your machine ).
It should work.

Thanks.

Thanks Bhupesh, but i already found the tiny little bug ( or is it a feature?).

What had no happened on planet VS:
My VS 2008 installation did not created a folder 'Addins' under XP c:\....\$username$\visual studio 2008\Addins or under vista c:\users\$username$\Documents\Visual Studio\Addins.
The installation path of this project puts everything into C:\program files\Microsoft\Visual Studio Pipeline Builder, but no registration for the VS-Addin is happening.

Solution:
1.: a.)get the sources. b) recompile the sources with VSStudio 2008, because the current version is VS2005 and set a correct the path in the addin-project.
2.: or if you don not have time:
a.)create the folder Addins in the path written above.
b.)put all sources like PipelineBuilder.dll, PipelineHints.dll, Template.csproj in the folder AddIns and it will work out just fine.

At last: greetings to Jörg Neumann: he wrote some real good articles about MAF!!

Have fun

Check whether your Visual studio 2008 AddIns folder has VSPipelineBuilder.AddIn.

A local problem? I have the same problems on two different machines! Any suggestions? Could that be a SP1 problem?

New Post: Pipeline advantages ?

Tischnoetentoet — Thu, 13 Nov 2008 10:39:05 GMT

Security because you can decide the security model to use to load a specific add-in. Also, for each add-in, a seperate AppDomain is created which is a good thing for isolation.

What benefits one gets through Add In Pipeline model apart from Independent versioning of Host and AddIn ?
Advantages of this design pattern ?
