How is the dll hell problem solved

Json version 9. This can easily create a conflict. You could make this work at runtime with binding redirects but it can lead to all sorts of trouble. The trouble depends on which version ends up being loaded. If it's version 8, then Library A can call a non-existent method, that exists only in version 9, and fail at runtime.

And if version 9 were to be loaded, then the same could happen with the startup project. In this case, you could probably update your startup project to use Newtonsoft.

But this same problem can manifest in a more troublesome manner, like this:. This is called the Diamond Dependency Conflict and it can appear in many forms. Unlike in the first scenario, you can't easily change the code of the libraries, which makes things more difficult. The best way to solve version conflicts is to prevent these conflicts in the first place. If you can change dependencies to use the same library version, then that's the best policy.

In the case of a diamond dependency conflict, updating the libraries sometimes changes their referenced libraries, which can match the right versions. Remember that the convention in C is that there are no breaking API changes in similar major versions. PATCH with the following convention :. Not everyone follows conventions, but if they do, then the requirement is just to match major versions, not the exact version.

When two projects reference a library with the same major version, make sure that the highest referenced version of that library is loaded into the process. This can be done with binding redirects see further on. For example, if Library A references Newtonsoft.

Json version 8. When referencing the code is in libraries, like in the case of the Diamond Dependency Conflict, changing their code to reference a different version might appear as a problem.

But licensing issues aside, it's entirely possible to change library code. In fact, it's easy. From there, you can do whatever you want, like changing referenced library versions.

Note that the version changes might require to change some code, but it will likely be a minor issue. Recompile into a new DLL and reference that to solve the problem. Of course, changing the library code in this manner is not very recommended. Dll hell problem was significantly reduced by this concept. This concept was used in Windows This method prevents unauthorized application from overwriting system dll.

If application uses the specific windows API then it only system will allowed to override. But there was a risk when there is a update required from Microsoft for the existing dll. How this problem is resolved? The Turn Windows features on or off dialog box appears. Select the. NET 2. NET Framework 4. NET Framework for many years to come.

In the Programs and Features window, select Microsoft. NET Framework version on Windows 10 and What is DLL hell problem and how. NET resolve it? Category: technology and computing video software.

NET with the introduction of Assembly versioning. Where is the GAC located? What is DLL file in Windows? What is GAC in C? What is DLL in asp net? What is DLL Hell in. NET framework? What is Assembly C? The reason for this issue was that the version information about the different components of an application was not recorded by the system.

Problem of Dll-Hell Introduction Before some time, if we install an application then dll of that application get stored in the registry, then if we install other application that has same name. Ok for newly installed application but previously installed application cant get execute further. This is big problem in context of version of same application.
