I have a visual studio solution which works fine on one machine and when I copy the complete same solution to another machine it misses few external dlls.
Both the machine have same configuration and same version of visual studio.
I tried removing reference and adding again.I am able to reference the dll and use code but when I re-build,It gives the same error.Any pointers on what could have gone wrong?
The error message I get is as below
The type or namespace name 'NameSpaceName" could not be found (are you missing a using directive or an assembly reference?)
Also the warning shows.
The primary reference "NameSpaceName" could not be resolved because it was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
Both the machine have Visual Studio 2010 installed. It works on one and doesn't work on another machine
The reference you have added to the project is likely not in a subfolder of your project but referenced from the Global Assembly Cache (GAC). Since you probably didn't copy the GAC, this reference is now of a different version. Figure out which (3rd party ?) component is affected and install an older version of that component.
Typically, Visual Studio cannot target .NET 4.5, unless you applied a workaround. In that case, you can go to the project properties, Application and change Target Framework from 4.0 to 4.5.

Am using visual studio 2015 but whenever i begin a new ion ionic2 project an error
MSB3644 The reference assemblies for framework ".NETFramework,Version=v4.0" were not found.
To resolve this, install the SDK or Targeting Pack for
this framework version or retarget your application to a version of the framework for
which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved
from the Global Assembly Cache (GAC) and will be used in place of reference assemblies.
Therefore your assembly may not be correctly targeted for the framework you intend.
After a research on the error i found out This link and This link but am using windows 10 on a 32 bit computer with program files folder and without the program filesx86 folder
Am not using any server and also a newbie to visual studio
I have also checked and
C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0. is there
I also found out you need to add
msbuild -p:FrameworkPathOverride="C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.
But am not sure where am supposed to add it
Can someone help me on this issue
But am not sure where am supposed to add it
Please run "Msbuild Command Prompt for VS2015"
Go to the folder of project
run the msbuild command
msbuild -p:FrameworkPathOverride="C:\Program Files\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0"
I've created a new project in Visual Studio 2013.2 with WebAPI and MVC enabled. Right out of the box, compiling the generated project and running gives me the exception. Looking around here, I've come across the following two questions:
Mvc 5.1 MissingMethodException System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached
System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached
Both these answers involve assembly redirects; however, in my case the assembly redirects are present and I'm still getting an issue. My problem is that the GAC is loading version 3.00.11001.0 which is listed under assembly version 3.0.0.0 and my application wants 3.20.20520.0 which is also listed as assembly version 3.0.0.0. (Note that in diagnosing the project I installed the 5.2 pre-release nuget package, but I had the same problem with the original versions, I just don't have those readily available)
Since the GAC is preferred over the bin directory, it seems that my development machine will always pull the wrong file.
Is it safe to remove these files from the GAC? It appears that these are required for Visual Studio to produce Razor intellisense
Removing the Assemblies from the GAC did behave exactly as expected. The Razor intellisense for the project stopped working; however, the application began functioning properly.
You have to add the reference of System.Web to get it working.
I am using Visual Studio Team Services as source control and have enabled continuous integration.
My project is an ASP.NET application which used Entity Framework 5. When i checkin the code and the build controller tries to build it, the following errors come up
DataModel\GenomicsTutorDataModel.Context.cs (40): The type or
namespace name 'DbSet' could not be found (are you missing a using
directive or an assembly reference?)
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets
(1578): Could not resolve this reference. Could not locate the
assembly "EntityFramework". Check to make sure the assembly exists on
disk. If this reference is required by your code, you may get
compilation errors.
In my solution i have made system.data.entity CopyLocal = True yet no success.
Any ideas?
May be you are on a 64 bits machine and the TFS server is not?
Try to build your project for Any CPU or x86.
Add the DLL you referenced for System.Data.Entity into a folder in your project or somewhere in a folder in the Source Control and reference to that one. Check this in and try to build your application again.
When I change the target framework of any project in Visual Studio 2010 it does not actually change the System assembly references. For example if I target v2.0 and check the properties of System and System.Data I can see that they are still both v4.0. If i change the target to v3.5, System stays at v4.0 but System.Core changes to v3.5.
Because of this I am truly not targeting anything except v4.0.
There may be something strange in your install. I just created a WPF project, keeping the default settings, thus targeting .NET 4. Then, I switched to 3.5. VS asked to reload the project and then the targeted runtime of the references was v2 (correct) and their version was 3.5 (with an error that Microsoft.CSharp and System.Xaml were missing, which is understandable).
Then, I did the same for .NET 3 and 2 and got the same results: after reloading the project, the version of the referenced DLLs had changed were it made sense (System.Data is always v2.0).
When using the CLR v2, the vshost debug helper had its name changed to something like vshost-clrv2.
I've reinstalled Visual Studio several times and it hasn't solved anything. After uninstalling there is 10.0 stuff laying all over the place leading me to believe the uninstaller is also leaving what ever is causing this issue. I'm going to have to reinstall the OS to get the issue to go away.
I also wanted to link to my earlier post because this post has more information about how I originally discovered this issue, contains a link to the Microsoft Connect bug report I opened and links to several other users experiencing the same problem: Visual Studio 2010 Can no longer build .NET v3.5
I have Visual Studio 2008 installed on my machine, but I haven't used it. I did open a dummy project and make sure that version 2.0 is the .NET Framework version I am using, since it is the one that suddenly doesn't work for me.
Here's the warning message I get when I am trying to open an existing Windows 2005 project.
"Namespace or type specified in the project level Imports 'System.Data' doesn't contain any public member or cannot be found."
All of the basic System, System.Data, System.XML assemblies show up in a new project with the yellow exclamation point warning.
Does anyone know how I can solve this issue? Please help!
I would start by downloading and re-installing .NET 2.0 on your system.
You could check the project references and make sure that you have System.Data added to the project.
