C# - How To Repair/Rebuild .csproj File From Code Files
Jan 10, 2011
I was working on a .Net 2.0 application. Late at night I upgraded it to .Net v.4. Then, as SVN was complaining I started to do manual conflict resolution. Even later than that I tried to check in my changes, then hit some conflicts so manually merged changes from the two different .csproj files.
I can't get back to where I was and rolling back to the previous version makes me lose all the code that has been written for it.
So I'm looking for a quick/dirty and reliable way of making sure my application code doesn't get lost?

As I understand it, I should be able to change an aspx file in VS, update in the browser and then see the changes without rebuilding the entire solution. For me thats not the case...
Edit: I use VS 2008, .NET 3.5 and development server. It is a Web Application project and I always need to rebuild to see the changes in the aspx files. I use master pages and aspx controls. I use edit and continue and have no problem updating the code behind files without rebuilding.

I've got a solution that contains several projects. There is a main exe project which I'll call MyProj.exe that references several other projects which reference yet other projects in the solution. Additionally a few projects in the solution are not in MyProj's reference chain and aren't regularly built. There is 1 project (a class library project) named Payment which is giving me a particularly hard time. The two of MyProj's references have a project reference to Payment.dll. So the reference heirarchy looks like this:
- MyProj.exe
- Transactions
- Payment
- Accounts
- Payment
When I right click MyProj in the Solution Explorer and choose Build, everything works fine, but when I choose Rebuild, I get the following results:
Payment.dll is deleted but never rebuilt. It doesn't exist in the output directory MyProj.manifest in the output directory doesn't have a reference to Payment.dll. (What is this file? I don't remember normally seeing it in other project's the output directories.) 19 of the project .pdb files are deleted and not rebuilt This is a big problem for me because this is a ClickOnce application and when I'm publishing, Payment.dll isn't getting included in my deployment which is a problem I suspect is closely related.

I'm trying to publish project (tools vs2010), but cannot all the time getting the error below. I paste to my projects files from another project and then I changed namespace (OldProjectName) to the parent project (NewProjectName). But it still getting information from somewhere about old project.
I cleaned solution, builded, rebuilded. Closed and reopened again and all the time the same error.

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:
myfile.ascx
myfile.ascx.resx
myfile.ascx.vb
myfile.dll
I'm using Visual Studio 2008 PRO.
I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.
The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".

I have too many lines in my code behind file. Now it grows up to almost 3500 lines. I wonder if it can be splitted into several files.
To be specify, say I have CustomerEdit.aspx and code behind as CustomerEdit.aspx.cs. In my code behind, most of them are functions taking care of UI (i.e. protected void ... _Click() or protected void ... _SelectedIndexChanged()). I have some private functions, but they usually refer to some UI elements.
Question: Can I safely seperate CustomerEdit.aspx.cs into smaller files like CustomerEdit01.aspx.cs, CustomerEdit02.aspx.cs, etc?

I have code that needs to run in two deployments. Let's call them deployment H and deployment W.
The code is already running in deployment H, and there's an aspx page and an aspx.cs code-behind file. The code is compiled for framework 2.0 which is the lowest common denominator of the two deployments. Deployment H has its own logos and styling which are coded in its aspx file.
Deployment W now wants to use this same page, but it wants its own logos and styling. There are also additional fields on the page that deployment H doesn't need.
I think it's easier to maintain one code base which is why I want the same code-behind file, but I am having trouble figuring out how to set this up in Visual Studio. Orginally, I was going to have two projects, one for W and one for H, but I'd have to make the same changes to both files when some of the common areas changes.

I have an ASP.NET application which I'd like to try running on Mono, just as an experiment. When I bring the application as it is to Mac, start xsp2 on the directory, it runs as I would imagine it should. That is, it crashes on because of the file system path differences ( vs / in directories).
This is where I would like to open it in MonoDevelop and fix the problems. But since it was website, it doesn't have .csproj file. And it seems that there's no .sln file either, since Visual Studio stores those to some random directory by default. In Visual Studio you could open the project with Open -> Web site... -> Local IIS etc., but I see no such thing in Mono.Is there a way to open a directory as a web site or somehow generate the .csproj file?

I have a designer working on several pages in Dreamweaver. The designer is creating .aspx files with the Page directive at the top. These are getting shipped to me and I'm adding them to the Visual Studio ASP.NET WebForms Web Application Project. The problem is that there's no code-behind file by default, and I'm trying to find a shortcut to have them autogenerated as if I've added a fresh page from Visual Studio.

Is there a way the Start page can be saved in the Project file of a Web Application project.
Right now it saves in the user file, I tried moving the tag in the CSProj file along with the IIS VD creation tag, but it didnt worked.

I'm getting "Cannot get pickup directory" under IIS 7.5. I've granted privileges to the mail folder to the IIS_IUSRS group. I recall from IIS 6 that I had to use to make some changes to the metabase using ACL tool.
Does the IIS 7.5 also use the metabase? Do I need to do anything with IIS 6 when installing pickup directory?

I was following the tutorials from this two sites:
http://www.15seconds.com/issue/070104.htm
http://aspnet.4guysfromrolla.com/articles/020404-1.aspx
Following the first site, it had worked but when I´ve moved the pages and files to other folders and set the web.config file on this folder, now it won´t work at all!!!
The file is an *.swf object. I did put the asapi.dll to map the extension on the website root, I´ve put the
[Code]....
on the web.config new folder and on the web.config website´s root.
It won´t work!!! I can access the file directly!!! on the web.config of the folder that contains the file, there is a <deny users="*" /> line.

I am developing a website for uploading files to our web server. The site was working last week when I first set up the website. However, I made some changes this morning and copied/pasted my new version on our webserver. Now whenever I enter the URL, I get the HTTP 404 error. The other sites I developed are still working. It is only the new website that is giving this error. I have checked to make sure I am spelling the file names correctly. An test html file loads fine in this subdirectory, but when I change it to the default.aspx, I get the HTTP 404 error.

have this error in server..
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

I'm working on an ASP.NET MVC web application and I've made my own authentication module, which is session-based (no cookies). The problem is: When I rebuild my application, I'm automatically logged of (session is empty).
Normally this is not a big problem because my application is not 'automatically' rebuilding in a production environment. But I've also made a module that changes the resource-files and after a modification of a resource file, the application seems to rebuild automatically.
So my actual question: Is it possible to 'keep' the session variables/stay logged on after a rebuild?
