I am trying to use the Mono.TextEditor assembly with .NET Framework 3.5 in GTK#. But I keep getting System.BadImageFormatException
Could not load file or assembly 'Mono.TextEditor, Version = 1.0.0.0,Culture = neutral,
PublicKey Token = null' or one of its dependencies. This assembly is built by a runtime
newer than the currently loaded runtime and cannot be loaded.
The MonoDevelop version I am using (Mono.TextEditor is an addon of MonoDevelop) is definitely built by .NET version 3.5. Any Help?
Most possibly your project still targets the 2.0 runtime.
You'll need to set Project/Settings/Build General/Runtime: Mono / .Net 3.5 in monodevelop.
Don't forget to add the reference to System.Core, if it isn't already added.

when i am setting Target .Net Framework to 3.5 and build the solution, it was showing [System.Bad_Image_Format Exception:'Could not load file or assembly 'interop.Redemption,Version=5.18.0.0'']
Interops are version agnostic. You need to re-add the reference to the project. Make sure the bitness of the reference assembly corresponds to your project's one.
I have several strange errors after using NuGet to add a third party library to a project. The project targets .NET 4.5.2.
The errors I get complain of standard system types not being of the correct version
e.g.
CS0012: The type 'System.Collections.Generic.IEnumerable`1' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
I have cleaned the project folder, deleted the bin folder, reinstalled the
NuGet package and readded the reference to no avail.
The library is Remotion.Linq
According to the Registry the following .NET versions are installed on the machine
v2.0.50727 2.0.50727.4927 SP2
v3.0 3.0.30729.4926 SP2
v3.5 3.5.30729.4926 SP1
v4
Client 4.6.01038
Full 4.6.01038
v4.0
Client 4.0.0.0
Does anyone know what is happening here?
This suggests the third party library targets 4.0 of the framework. You either need to find a later version of the library or in your project properties set the target framework to 4.0 as opposed to 4.5
This turned out to be a misleading error. The library was built against .NET 4.5.2 but I had .NET 4.5.1 installed.
Microsoft explain this in a KB article (KB2971005) but you really need to know what the issue is to easily find the article. I somehow stumbled across it after a lot of searching.
The resolution is to install the updated version of the Microsoft .NET Framework 4.5.2 Developer Pack.
I'm facing a compatibility issue for .NET project.
I have 2 projects:
1st project: Libary project. Target: windows Phone 7.0 OS version
project
2nd project: Console Appplication project. Refers/use the previous
library. Target: Framework .NET 3.5
When I try to run the 2nd project, I have an exception that happens when I call a function from the 1st library:
...Could not load file or assembly 'System, Version=2.0.5.0,
Culture=neutral, PublicKeyToken=7xxxxxxxx or one of its dependencies.
The system cannot find the file specified...
If I change the target for 2nd project to Framework .NET 4.0, it works well, no more crash.
Is my error really due to the different target versions ?
How can I make the 1st project to be compatible with framework 3.5 ?
As I said, 1st project was targeting framework 3.5 .NET and 2nd project was targeting Windows Phone 7.0.
Work around: change 2nd project to target framework 3.5 .NET. (in my case, I add to create a new project in my solution, which in fact was the same as the old one but targeting framework 3.5 .NET. Same sources used.)
Kindly rough but works.
I had excactly same issue. Installing Portable Class Library helped me.

There are links to downloads for different visual studio versions.
I have a MVC 3 application that targets .net 4.0 It has a dozen or so projects also targeting .net 4.0
I have created a new project for the solution targeting .net 4.5 that uses reflection (there are a couple of nice bits of functionality in 4.5 that I want to use). When I try to compile I get an error saying that the 'type or namespace (new 4.5 proj) could not be found, are you missing a directive or an assembly reference'.
Is it possible to have a reference to an assembly targeting .net 4.5 in a project that targets 4.0?
Is it possible to have a reference to an assembly targeting .net 4.5
in a project that targets 4.0?
No. It shouldn't be. There could be some features that are used in .Net 4.5 assembly which are not part of .Net 4.0, In that particular case, it should fail.
I guess you could just set your project to .net 4.5, but if you would like to keep it as 4.0, take a look at this link might help you
Yes, it is possible. Just open the .csproj file for the .Net 4.0 assembly giving the assembly load error in a text editor and set this for the .Net 4.5 assembly reference:
<SpecificVersion>True</SpecificVersion>
I receive the following error:
Cannot load assembly. Error details: System.BadImageFormatException: Could not load file or assembly 'file:...' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
This assembly is built with .Net Framework 4.0 and i made sure that all projects in my solution are also built with .Net Framework 4.0.
Any idea why i am getting the error? How can i check which frameworks are loaded with my application?
What is the main executable, i.e. the assembly responsible for deciding which version of the CLR is loaded? Note that it's not just a case of being built by .NET 4 - if your executable targets .NET 3.5 or lower, it will load in the .NET 2.0 CLR, and your .NET 4 assemblies won't load.
Hello I Had the same problem until i follow these hints: BadImageFormatException Class (section "Remarks")
In my case I was trying to load assemblies with call to umnaged code.
