How do that .Net project runtime determine load which assembly

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :WPF
 
I have a .Net 2.0 prject , and need call .Net3.5 assembly. If the machine set up .net3.5, it can work;  otherwise it will throw exception. Now I want to prepair two aseembly, .net2.0 and .net3.5. They are same source and IO, but .net2.0 disable some .net3.5 functions. When I found the machine doesn't support .net3.5, I call the .net2.0 aseembly. How do it?

How would runtime determine which assembly to load?

  
Hi , How would runtime behave, if I have an assembly with same version number in two different folders on my machine? How to restrict the runtime to read from bin folder only for my specific assembly?        

Could not load file or assembly - Web Deployment Project

  

Hi,

I have the following projects in a solution :

- A Web Application

- A Class Library

- A Web Deployment project

The Web Application compiles and run fine when I don't go through the Web Deployment Project. However when I try to use that, I get the following error:

Error 1 An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified. (F:\Folke\Folke.csproj_deploy\Release\web.config line 4) 1 1 Folke.csproj_deploy

"An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified. (F:\Folke\Folke.csproj_deploy\Release\web.config line 4)"

This is the beginning of my Web.config:

Specify [TARGETDIR] in Setup project (msi) runtime

  

I am not sure if here is a proper place to ask this question. I look for other forums, and don't feel this question can fit in any. If this is not a correct place to post, I appologize. Please let me know where I can get answer for this question. Thanks.

Here is my question.

I wrote a website, and not I am trying package it with a setup program (msi), so I created a "Web Setup Project" and specify outputs as the standard tutorial on this. And then I'd add custom action to msi which modify Web.config file during msi installation. Output looks ok, but msi install the website under "C:\Inetpub\wwwroot" folder, and I don't have control on it. I followed an example (http://www.codeproject.com/KB/install/ChangeVDirWebSetupProject.aspx) use orca.exe to remove WEBCA_EvaluateURLsMB, WEBCA_EvaluateURLs and WEBCA_EvaluateURLsNoFail from corresponding tables in msi and provides TARGETDIR value while calling the msi file. And then I fall in a problem, either the custom action is not called any more or I get a error "Configuration file cannot be created".

Can Not load WPF project in Visual Studio 2005 on Win7 64 system, says "Project file not supported b

  
Dear all I am facing an issue in creating new wpf project or loading a WPF project in Visual studio 2005. I have installed Visual Studio 2005 Service pack - 1 (http://www.microsoft.com/downloads/details.aspx?familyid=bb4a75ab-e2d4-4c96-b39d-37baf6b5b1dc&displaylang=en) but still I can not see the option for wpf project  while creating a new project. Generally we can see WPF listing under item File -->New-->Project--> ".Net Framework 3.0" in VS 2005. I have few WPF project and when i try to load them it says "Project file not supported by this Installation". My System Config is given below: OS: Windows 7 (64 Bit) VS: Visual Studio 2005 with Service Pack 1 .Net Framework: 3.5 (By default inbuilt in Win7 OS)   I am suspecting something bugging related to .Net framework 3.0 in Win7. We have one option in control panel to alter .NetFramework 3.5 under "Turn Windows Features on or Off" but there I can not see something related to 3.0 :-(.   Kindly suggest how can I load my existing project and how can enable option to create new wpf Projects.   I saw few solutions suggested by people on following Thread bt most of them related to Windows XP or Vista: http://social.msdn.microsoft.com/Forums/en/vswpfdesigner/thread/06cf7bca-982c-44cf-aec9-99cf399b3000 Do someone has solution for Windows 7 (64 bit OS)

Slow load time of custom assembly on x64 compared to x86.

  
I am developing an application that automatically generates assemblies using the CSharpCodeProvider (.Net Framework 3.5).  These assemblies contain a single class with a very large number of local variables and methods.  After compilation I create an instance of this class (using Activator.CreateInstance) to be used elsewhere in the application.  When the application is deployed on a 32-bit system (tested on Win 7 Prof 32-bit and on Win XP) the CreateInstance method returns after 1 or 2 seconds, i.e. it first JITs the assembly before creating the instance.  However, on a 64-bit system (tested on Win 7 Home 64-bit, Win Server 2003 64-bit and Win Server 2008 64-bit) CreateInstance takes up to 5 minutes to return. Is there any reason why it would be that much slower on a 64-bit machine? I have tried many different options when compiling, such as setting the platform to x64, using the /optimize flag, etc, but none of these have made a difference. I also tried calling PrepareMethod on all the method in the class.  When I do this in the 32-bit environment, it takes approximately 10 seconds.  In the 64-bit environment it takes more than 3 minutes. As a last resort I tried ngen before constructing the object, but this made no difference in the execution time.

Load dynamically assembly with dependencies

  
I'm trying to download .dll by having some url (http://somedomain.com/myassembly.dll) and load it into appdomain. Once I download this assembly I can't load it into appdomain, because it has some dependencies. Some of these dependencies I can found on my local machine (such as .NET libraries), but some of them I have to download and load into appdomain. So there are several questions: 1. How to determine list of dependencies without loading assembly into appdomain (and by having only byte[] as assembly) 2. How to determine which of these dependencies can be found locally Thanks, Paul.
