I need to look for specific types in all assemblies in a web site or windows app, is there an easy way to do this? Like how the controller factory for ASP.NET MVC looks across all assemblies for controllers.
View 3 RepliesPart of a web application we have uses an in-house web control assembly. This assembly contains several web user controls where several of these are used by other web controls within the same assembly.
The assembly is built as a website with a web deployment project.
The main web application's pages are dynamically compiled through a service into a single assembly and placed into the appropriate bin folder. In our development server the old assemblies aren't always tidied up and removed, meaning the folder gets full of old assemblies.
When the page that uses the in-house web control assembly (mentioned above) runs, the asp.net instance throws an out of memory as it loads all the old assemblies in an attempt to determine which assembly houses the reference to the user control being used by the other user control inside the same assembly.
We've been using the following inside the top level user controls to register the other controls
<%@ Register Src="~/....ascx" TagPrefix="UC" TagName="...." %>
Of course when the application runs this gives no information as to which assembly it can find it in.
Is there anyone that's come across this problem before? It's not really a problem as our live servers use a clean up tool to remove old assemblies, but there are still potential situations where we could get out of memory caused by this (for example the tool stops working!), so it would be nice to resolve this problem.
Here is the stack trace

When I use Project Reference to add dependent assemblies to my C# library project, I can use the "Go To Definition" popup menu item to go to the source file of the class defined in the dependent assembly. That is one of the most useful features of VS for me. However, when I add dependent assemblies as BIN References (via the Browse tab of the Add Reference dialog), I only get the class definition generated from metadata of the dependenat assembly, not the source file.
I realize that intellisense can't find the source directory of the dependent assembly, but where can I enter the directories so intellisense would know? There is a "VC++ Directories" page in the Options->Projects and Solutions dialog, but that is only for C/C++ projects. There should be one for C# as well. The bigger mystery is when I put my project in the debugger, I can step into methods defined in the dependent assembly and see its source file. Why could the debugger find the source file but not intellisense?
when I reference a assembly. It's reference gets added to the project file in my case ( ABC.csproj)
Also when I take a look at the web.config file there is a section called <assemblies>. And lot of assemblies are added there.
What is the difference between link to the assemblies in the Project file and the assemblies in the web.config file?
I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.

I just need to ask something about .net assemblies. I'm sorry if this question may not be appropriate for this forum but it is very urgent and very important for me to answer so if any kind person can answer in simple and in detail about 'What are assemblies?' I googled about this but I got only one line definition for assemblies rest is only about private ,shared, manifest etc. etc. but I need to know what are assemblies.
View 8 RepliesI have an ASP.NET MVC 2 app targeting .NET 4 that needs to be able to resize images on the fly and write them to the response.I have code that does this and it works. I am using System.Drawing.dll.However, I want to enhance my code so that not only am I resizing the image, but I am dropping it from 24bpp down to 4bit grayscale. I could not, for the life of me, find code on how to do this with System.Drawing.dll.But I did find a bunch of WPF stuff. This is my working/sample code (runs in LinqPad).
// Load the original 24 bit image
var bitmapImage = new BitmapImage();

In 2005 you need to add a new registry setting in order to see it in the Add Ref dialog box.
BUT
can you add a reference an assemble that are in the GAC in the web.config file?
I get that assemblies store data about an application, and its components. I am still clouded about several vital functions of this very basic concept and cannot for the life of me find a complete all inclusive reference or explanation of this topic. Exactly how far reaching is this within c#.net development? Where is it stored? How is it stored? Exactly what, in it's entirety is in it and how is it used and when? Please, please do me a huge favor. Do not send me on a wild goose chase to some self serving, obscure site with partial explanations that wastes my time. By the time I'm done studying the information within your referenced site or response, I want all of my questions answered.
View 1 RepliesI have an .net assembly build against 3.5 framework. This assembly has a class Foo with two method overrides:
public class Foo {
public T Set<T>(T value);
public T Set<T>(Func<T> getValueFunc);
}
I'm referencing this assembly in my asp.net 2.0 web application to use first override of the Set method (without Func).
But on build I get an error saying that I should reference System.Core to use System.Func delegate... but I'm not using this type...
Is there a workaround to solve this?
PS: There is no option to convert my web application targeting 3.5 framework.

View 2 RepliesI'm trying to write some code to use reflection to load new assemblies. I observed the file system with FileSystemWatcher, so that if anything in the folder changed, I can get notified and then reload them.
Firstly I have an assembly filters.dll loaded. Let's say its version is 1.0.0. Then when I have a new one v1.0.1, I paste it into the folder and replace the older one. Of course this fires "Change" event of FileSystemWatcher, and finally lead to assembly reloading.
Everything works fine, but I just want to know, what would happen to the firstly loaded assembly? Get replaced by the newer one? Or still somewhere in the memory?
In the web.config of my site 'MySite.com' I have some assemblies such as
<add assembly="aspNetEmail, Version=3.5.2.0, Culture=neutral, PublicKeyToken=BC571E8DA1C1F543"/>
we have an asp.net web site (web application project of vs 2005) where we have a main project and same secondary projects which contain same apsx/ascx used by the main project.
for example in an aspx page of the main site we will use same ascx defined in another project)
at least with vs 2005 we must do a lot of hack to make it works becouse it's not possible to directly reference another web application to use aspx/ascx defined there.
i want know if upgrading to vs 2010 and mvc can help us to a better organization of this type of architecture (the best things will be if i can add a view as embedded resource of a project and i can use it by another project, as the server control of asp.net form)
In my web application I am using NHibernate.dll. This has a dependency on folowing assembly.
'Antlr3.Runtime, Version=3.1.0.39271,
Culture=neutral,
PublicKeyToken=3a9cab8f8d22bfb7'
Now in the same project for another requirement I have to introduce Antlr3.StringTemplate.dll. Which has a dependency on another version of the above assembly.
If I use the version of Antlr3.Runtime.dll which satisfies NHibernate , Antlr3.StringTemplate starts complaining and vice-versa.
I have a collection of assemblies using reflection. I want to loop through them, but I would like to ignore the .NET framework or ASP.NET framework DLL's. Is there an attribute on the assembly that marks that its from the .NET framework? Or any other designation?
I was looking at the name, and if the name of the assembly starts with System, Microsoft, or mscorlib, I am ignoring it. But I was wondering if there is a flag I can use to make this even easier?
When looking at ASP.NET MVC 3 and WebPages (the 'simple' web application framework used by WebMatrix) I noticed that these frameworks take a dependency on assemblies and/or namespaces that do not fit the familiar naming style for ASP.NET:
- Microsoft.Web.Infrastructure
- WebMatrix.Data
- WebMatrix.WebData
- Microsoft.Web.Helpers
Most if not all assemblies/namespaces up until and including ASP.NET 4 and ASP.NET MVC 2 are called *System.Web.** Why did they do it? Is this 'a trap' or is that too cynical? Some context (from the [Mono 2.10 Release Notes][1]):

I'm trying to understand the relationship between assemblies, namespaces and classes. Can anyone help explain or point me to a usefule link?
1. I understand that an assembly is typicall a dll or an exe (perhaps other files also). Does each project compilation produce only 1 dll? Or is the number of DLL dictated by something completely different?
2. I read each assembly can contain multiple classes. Asingle assembly can contain classes for multiple namespaces, and asingle namespace can span multiple assemblies.
Can anyone tell me what does the term Output Assemblies designate to. Are these the compiled pages of the Website Project or something else ?
View 2 RepliesI'm currently implementing some DataProviders according to the ASP.NET Provider Model. Everything works fine, though the application directory is a mess due to all the assemblies containing the data providers and their dependencies.
Is it possible to put the assemblies containing the DataProviders in a subfolder? If yes, what do I have to change (in the app.config?) so that the assemblies will be found by the application?
This is my current entry in the app.config:
<CustomerProvider>
<providers>
<add name="SqlDataProvider" type="SqlDataProvider.SqlCustomerDataProvider, SqlDataProvider"/>
</providers>
</CustomerProvider>
In context of an ASP.NET Website project, is it possible to create a second location where DLLs will be picked up from, in addition to the regular bin/ location and apart from the GAC? I expect such a feature would be made possible by the configuration.
