Visual Studio 2010 Puts 4.0 Classes Into 3.5 Project?
Jun 21, 2010
I have existing ASP.NET 3.5 project I migrated to Visual Studio 2010. I didn't migrate it to .NET 4.0. Every time I try to edit .aspx page, it alters the .designer.cs class to point to System.Web.UI.WebControls.WebParts.UpdatePanel class instead of
System.Web.UI.UpdatePanel
class and then the build of course produces an error. The project properties says ".NET3.5".Also the "design" tab produces just one box saying "unknown server tag asp:UpdatePanel". It seems like it is looking at .NET4.0 to generate the desgn view, not 3.5
I'm using VS 2010. I got the references to the classes from my project, now I need the .dll files but I can't seem to find them. How do you add the .dll's?
Does anyone know why VS2010 will automatically put an open and close html paragraph tag in my markup everytime I click on save, or save all? It is really obnoxious. I have to close the document and click yes at the prompt to save in order to save my document. If I click save, or save all, it will always place a paragraph tag somewhere in the code and therefore it will need to be saved again.
We have shared CSharp classes put into a shared folders for re-use. Now I want to add those classes into my project by creating a new folder:
1) Right click the solution, Add -> New Folder Give it a new, eg. SharedClasses
2) Right click the new folder "SharedClasses" Add- > Existing Item...
Browse to the "Shared Folder", include those shared classes. But those files are added physically into the folder "SharedClasses" rather than a reference. How do I just add a link to those shared files? Since these files might be modified from time to time, I don't want to delete and add those file frequently.
I've build a Class Library, in the same project i put a web project. But its impossible to access the classes from the dll generated by the class library. Whats wrong? JumpTide XML uses the namespace like:
namespace JumpTideClassLib { public class jumptidexml { public class MetaTags {
Im working on a website project with Visual Studio 2010 from 2 different computers (home & work). In Dreamweaver Im used to FTP to upload/download files to/from a webserver to syncronice my files on the current computer Im working on.What is best option in Visual Studio 2010 to sync project files between home & work computers? I have seen there is a built in FTP, but seems only it can upload files, limited functionality?
when i opened my Visual Studio 2010 i noticed that my ajax tab was missing from my toolbox and ajax control kit too.Then i noticed even that when i create new website, there is no web.config in it and it should be.WHAT IS GOIN ON???? :/
I've searched but not found much that helps, could be using wrong search terms.Anyway, currently using Visual Studio 2005 and VB, but just got Visual Studio 2010 and trying to use C# and am having problems using classes, I think I'm missing something simple here.
In both 2005 & 2010 I create a new website and a Default.aspx, in 2005 using VB, C# in 2010.
Right-click the project -> Add New Item -> Class, and leave it as Class1.vb/Class1.cs
Both 2005 & 2010 prompt to place it in the App_Code folder, so choose yes.
Here are the class files, I've not changed anything apart from create a very simple function:
Class1.vb code: [Code]....
Class1.cs code: [Code]....
In my VB project Default.aspx.vb: [Code]....
No errors, and debugging shows that a = "hello"
My Default.aspx.cs: [Code]....
This gives an error:Error 1 The name 'tester' does not exist in the current context D:Visual Studio 2010WebSite11Default.aspx.cs
How do I reference the tester function within Class1 in my C# project?
I have downloaded a project from the internet called the SMS Source example. I wanted to open this project in VS2010, so a conversion wizard has popped up prompting for the conversion. But it has errors in converting.
im facing problem to access classes out side my project folders. for example if i want to use some methods from store.vb file inside my project i get error : Name Space is not defiend, i have tried all ways such as import sdf.ITracjer.Data
[Code]....
i can't fetch the Store Class Methods or Function because its out of project directory, as its showin in image.
I recently updated my VS2010 website project from .NET 3.5 to 4.0. Everything was working fine in the website project. Today I decided to migrate the website to a web application project as I have learned this is the best way to work in .NET. I split out all my class files into a separate class library and copied all my other content into my new project. Then I updated all the references and web.config.
When I build the class library, everything works great. The problem is happening when I try to build/debug the web application project. It is acting like all the controls are missing and it is also throwing a bunch of compile errors about the public properties I have in my master pages.
Control errors: "The name 'INSERT CONTROL NAME HERE' does not exist in the current context"
Master page errors:'System.Web.UI.MasterPage' does not contain a definition....
It is giving these errors for every single control and master page property in my entire solution.I notice when I add a new web.form to this project, it also adds a filename.aspx.designer.cs file in addition to the .aspx and .aspx.cs file. My existing files do not have these extra files since they were created in a different .NET version.
UPDATE: It seems I was missing the step where I need to right click on the new application folder and select "Convert to web application". I just did that and it seems to be a little bit better...
Now it is choking on Literals that are inside single quotes:
For now, I just want to use the <audio> and <video> tags and maybe try out the drag and drop features since these are supported by Firefox 3.6. The project will just be a test project, not necessarily for production.
So I got a copy of Visual studio 2010 ultimate through my university and MSDN AA. I've been unable though to create any MVC2 projects in it. Even worse when I save my project from school and attempt to just open it at home I keep getting errors that it can't load the project (this included just open a basic empty project). I've tried a complete reinstall, and even manually downloading the MVC2 RC.

Today in one of the computer i installed visual studio 2010 professional edition, and successfully installed. But in my new project template "Asp.net MVC 2 website" is missing. Also I'm not able to open an already created MVC 2 project also. I'm also having MVC 2 installed with VS 2008 Sp1 in the same machine and is working fine. I uninstalled and installed again, the same is happening.
I have an asp.net mvc 1.0 project. I upgraded the project and solution to Visual Studio 2010. However, I do not want to use asp.net mvc 2.0. My app compiles under mvc 1.0. All my references are to 1.0. I have copy local true and i am referencing mvc 1.0 from a lib folder, not the GAC.However I keep getting this error:
No parameterless constructor defined for this object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Its like it wants to keep using asp.net mvc 2.0, because its complaining about that GetControllerInstance method. This project works fine in vs 2008.
at vs2008 i could set App_Code folder, but at vs2010 i can not do it, that's why i put my dataset's and class' to App_Data folder. Either I do not know even App_Data folder is secure?
the problem is that, my web project developed in visual studio 2008 but i converted as a visual studio 2010 project. when i am try to run this project that showing the error message that
I'm trying to create an ASP.NET Web Application, but this is all I see: I have confirmed that I have the full Visual Studio installed, not just Visual C#.Why can't I see ASP.NET Web Application in the "new project" list?
how I can enable .asp files in a simple VS2010 Website project? For example: Start VS2010 Click "File/New Web Site..." Accept defaults Add an html file called "Test.asp" Attempt to open Test.asp (debug project with that file active) and you get the following error: "This type of page is not served. ... is not server because it has been explicitly forbidden. The extension '.asp' may be incorrect " SO, HOW DO I EXPLICITLY ALLOW IT? VS2010 is using the ASP.NET Development Server....
Is there a way to make a new project file using Visual Studio express 2010 using the files downloaded off a server from an asp.net web site? If so what are the steps? I would like to make a new project out of the old files without starting from scratch, I don't want to just edit a couple of things I would like to create a project file using the files I can get off the server if possible. It would be C#.
