So i have never encountered this type of error(well warning) before and i am not sure how exactly to go about rectifying the issue. Of course due to this warning several errors come up when i attempt to call anything that requires this reference.
The warning i get is:
"the referenced component "Telerik.Web.UI" could not be found."
What my questions are about this problem, are what is the reason for Visual Studio to be unable to find a reference even though it appears to be there?
Is there something extra i need to obtain in order for this particular reference to work?
How exactly would i go about fixing this issue?
Also as a side question: how exactly would i have go about dealing with this issue for any reference with Visual Studio, or what would be the steps to go through in order to solve this problem?
Update 1:
Okay so after spending some time messing around with it i ended up just deleting the reference and readding it.
This solved the problem, however i am still interested in understanding why this would occur?
So new question to be considered: Why would a reference be considered as "not found" even though it is in the correct location?
Update 2:
Okay so continuing with reference issues, i found this one to be interesting and i have no idea why it is occuring. So my problem is that i am attempting to use the reference
CrystalDecisions.CrystalReports.Engine
The pathway for this reference is:
C:\Program Files\Business Objects\Common\2.8\managed\CrystalDecisions.CrystalReports.Engine.dll
So what i want to do is use this same reference, except instead of the 2.8\managed*
I want to use the version of this reference from the 4.0 directory in the commons directory. No problem all i have to do is delete the current reference and just manually browse for this in the 4.0 directory. However, when i do this i end up having the pathway in the properties folder continue to say it's coming from this location:
C:\Program Files\Business Objects\Common\2.8\managed\CrystalDecisions.CrystalReports.Engine.dll
What i would like to know is why is this happening? Does it mean that i am still not obtainning the correct reference folder and how do i go about correcting this problem?
Any help or suggestions on how to solve this problem are greatly appreciated.
Thanks.
Make sure your project isn't configured to use the Client Profile.
Right click on your project and select Properties. Click the Application tab. In the "Target framework" box, select whatever framework you want to target, but the one without Client profile at the end.
This answer is a great resource that explains why the Client Profile can't be used in your case: The referenced project x does not exists

I am working on a rather large project in visual studio, and I have several references to other solutions and projects within my current solution. One of my user controls resides in a separate solution, so I need to consistently be able to update the DLL to fit any changes to my code. The only problem is, Visual Studio will not update my references unless I go through a long, meticulous process which I will try to describe now:
First, I must clean and rebuild the solution that contains the changed code. Here is a snippet of the class I need to update:
I just added the highlighted property, so my other project does not recognize it yet. I used blank properties like HelloWorld and ISuddenlyDespiseYogurt because they are easy to spot in code and properties will show in the compiled version of the code.
Secondly, I must go to the project I am trying to use the DLL in, delete the reference, and re add it.
I right click on the reference I want, click delete, then right click on the "References" tab, press "Add Reference", then I use the file path of my other solution and update the reference.
Lastly, I must restart Visual Studio and reopen the project I was working on.
And now our new property is recognized by my project. This solution works every time, but it is a ridiculously annoying workaround, and I am hoping someone out there knows how to make this process much easier.
This is the closest thing I can find to a similar problem on StackOverflow, and the rest of the internet is no help. If anyone has any clue how to fix this problem, I would very much appreciate your insight.
I have a feeling that your project is copying the library .DLL to your project folder, instead of linking over to the Hamilton.HST project's Release folder.
Two things I would check from your side: when you're linking the reference and clicking 'Browse', where exactly are you grabbing the .DLL from? Hopefully the Release folder, or some other output that changes when the Hamilton.HST project is recompiled. And second, check your main project and the properties on the Reference, to make sure it's pointed to that Hamilton.HST folder (like I said, I have a suspicion its pointing to somewhere in your second project's folder, and that VS copied the DLL over instead of linking.)
I managed to fix the problem, hopefully for good. For the sake of anyone else who may have this problem, here is my solution:
I went into the "Properties" tab of my project, by right clicking on the project name in Solution Explorer and clicking "Properties". I then navigated to "Build Events", where I saw something like this:
The first two lines were there when I opened the window, and I added the last line. From what I can gather, the addition of that line tells my program where to look for updated DLL's upon building the project, and I had the wrong location before.
Other than that, I have no idea how this solution worked, but hopefully it can work for someone else. If anyone knows the logic behind this solution, please let me know so I can clarify my answer. Thanks to everyone who gave me suggestions to fix this!
Visual Studio 2019. The error was misleading in my case. After building one project at a time, I ran into the actual build error in one of the projects, which prevented that project from compiling and therefore caused the missing dll error. Once the issue was resolved, everything built properly.
So I've had this problem for a little while now and looking at all the answers, I can't seem to fix it. My problem is this:
Upon deleting the folders in my Bin directory...
A heap load of errors (are you missing an assembly or reference for ...EVERYTHING?)
So I Remove and add references, the problem still arises.
I'm starting to question my own sanity here. Am I mistaken in thinking that the release/debug folders should fill up with dlls when building?
Attempted fixes
Checked hint paths, they are correct.
Did the old "untick retick the build checkbox" trick in the Solution Properties page.
Set Copy Local to True
Crossed my fingers and prayed really hard.
Currently to prevent this problem from occurring I'm having to create a new empty project build that project with the same version references and copy the compiled dlls over! Someone save me!
So after some prompting in the right direction by NDJ and bdn02, I found the problem:
My previous attempts to fix a specific dll were falling on death ears because the problem was with a different dll that all other dlls depended on.
When setting copy local to true I didn't realise it was being set to false the moment I came off the properties pane (Really it should prompt the user by informing them it can't set copy local to true, rather then silently change a users' input... But w/e). this made me curious, I compared the properties pane to the empty solution with the same reference and it turns out the "Path" attribute was missing from the property.
There are two ways to fix this, open your csproj in a notepad, find the reference and update the hint path, or uninstall and re install it... Reference problems can be a real pain.
I am experiencing a random issue with the SCSF 2010 guidance package when I try to add a View with Presenter in my VS2010 project. This also happens when I try to add a Business Module as well.
The issue seems to happen randomly because the same exact solution opened in two different locations, one will let me add views and the other one will throw the exception. Its really mind boggling. Sometimes it will let me add Views no problem, sometimes it just crashes.
I have to check out an earlier version of my solution from source (which I know will let me add views) and create everything and import it into the most current version.
It seems to be related to this WCSF issue but I had no luck with the solutions proposed here.
http://webclientguidance.codeplex.com/discussions/263101
Deleting the gpState and re-enabling SCSF did not help.
This is the error:
Microsoft.Practices.WizardFramework.WizardExecutionException: The wizard failed to execute. The error was:
Unable to cast object of type 'Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSyntheticConfigSettings' to type 'Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ContainerModel.ITypeRegistrationsProvider'. ---> System.InvalidCastException: Unable to cast object of type 'Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSyntheticConfigSettings' to type 'Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ContainerModel.ITypeRegistrationsProvider'.
I believe this is the answer to your problem.
The problem can be resolved by removing a Page Flow project and the Page Flow settings in web.config (including connection string and http modules).
Which you can find here.
Recipe Framework Error when adding page with presenter.
... some users have also suggested that deleting the .gpState file of the solution, re-opening the visual studio & solution and re-enabling WCSF Guidance seems to fix this problem temporarily. Please, create a backup of your .gpState file before trying this approach.
After I build a few of my references, which are present in the project and accessible through intellisense before the build is performed.
Unfortunately none of my projects are set to target Client Profile, as answered in this thread.
The type or namespace name could not be found
This seems to be the most common cause, does anyone know what else other than this can cause the same issue?
Edit:
The Types that aren't found are all from the referenced DLLs. I have the correct using directives for these and they are present in the resource folder, however they become underlined red after a build (I did try cleaning to).
My initial thought was the framework (the project is on v3.5), but I checked all my resources working or otherwise all where on v2 bar a few (working ones) on v4 which I removed temporarily to make sure we're causing issues.
Unable to access the project from my current location but will post any requested specifics as soon as I can.
edit:
Resolved the issue by deleting all of the custom class libraries... found and rebuilt each of their projects then added the new DLLs back into the project. Stored libraries weren't very organised, so I probably have some confliction between old/new versions.
Have you read the warning in the error list? You might need to install nuget package used by the referenced projects
for me the error warning was
All projects referencing "project file" must install nuget package Microsoft.Bcl.Build.
Are the projects being built correctly ?
Sometimes, you need to manually generate them (right click on them, generate), before being able to run a full build.
I dont exactly know why, but this might be the way to go for you.
~A few simple things to try before getting into more complicated water...
Try clicking:
Build->Clean Solution
Build->Build Solution
If this doesn't work, check your using statements are all there and correct, check your references all still exist.
I had a similar issue today, and I thought I would mention it here in case it helps someone else out. In my case, I have a VB.net Class Library which is referenced by a C# class library. The solution would build fine, but in the IDE, as soon as I started editing a file in the C# project, I would get errors about not finding a reference to the VB.Net library. It turns out that the VB.Net class library had a reference to System.web (lowercase w). I'm not sure how that came about -- but the solution was to delete that reference and replace it with a reference to System.Web (uppercase W).
Make sure all the projects in your solution have the same "Target framework" value
I've just come across a pretty strange problem with VS2010 and Script#, which most of the time I am able to re-create.
In my simple scenario I have 2 projects in my solution; a standard Asp.Net MVC2 Web Application, and a Script# jQuery Class Library. I created a static class (attributed with [Imported]) with a static method on it, the intention being that I can map this class in code to an external Javascript library, as described in the documentation.
However, it seems that whenever I decorate such a class with [IgnoreNamespace] to achieve this goal, the project stops successfully compiling but doesn't give me any feedback as to why it's failing (no errors in the error window, for example). It's not easy to get rid of either, as Visual Studio seems to get into a permanent state of not build failure; removing the classes and project files doesn't solve it, nor restarting visual studio. The only way I can get VS to build the project successfully is to delete the project entirely, create a new one then add the files back in, which is annoying to say the least.
With a verbose build output setting, I get the following:
Target "AfterCompile" in file "C:\Program Files (x86)\ScriptSharp\v1.0\ScriptSharp.targets" from project "e:\project\local\ScriptSharpDemo\Scripts\Scripts.csproj" (target "Compile" depends on it):
Task "ScriptCompilerTask"
Done executing task "ScriptCompilerTask" -- FAILED.
Done building target "AfterCompile" in project "Scripts.csproj" -- FAILED.
.. which doesn't tell me whole lot.
There have been a couple of times where I have managed to create this type of class and then successfully build, but mostly I can reproduce this problem pretty reliably.
At this point I'm inclined to think that the bug lies with Script#, but would just like to have that confirmed, and to find a possible work around if there is one.
Just in case anyone is having a similar issue, I've found the cause of the problem.
When adding a class using this method, or copying in a file from another project for use within Script#, this causes a reference to System.dll to be added to the project. This (understandably) causes the project to stop compiling without error.
It would be nice to have a warning about this or for Script# to somehow detect when this situation occurs and/or create a new template for when I use 'Add class' or import a file, but it is just a convenience issue and at least now I can painlessly get my project compiling again just by removing this reference.
When trying to make my project build again, I came across the following, possible solutions:
The "Home\HomePage.cs" and "Shared\Utility.cs" must not be deleted and remain where they wre initially created
The "Home\HomePage.cs" and "Shared\Utility.cs" must be the last entries in the "*.csproj"-file. After them, no "Compile" tag should follow
Problematic calls to "Script.Literal" might cause silent fails - especially be careful when having parameters (like Script.Literal("{0}.doFoo()", variable))
The same seems to be true for "String.Format" when the format parameters are invalid
Namespaces and folders seem to cause many problems, putting all classes into the same namespace and all classes into the same folder might help
I tried all of the suggestions that have been given here, but continued to see the issue. Eventually, I determined that the cause in my situation was that I had added an [IntrinsicProperty] attribute to one of my properties. Removing it solved the issue. Don't ask me why this was causing a problem, but I thought I would share this solution in case others run into it.
