They make sure that you can’t “fake” assemblies.

Or if you want to load different assemblies according to customer configuration, that’s also OK. For example, if you want to load different assemblies according to different cultures (languages), then you can do so easily.

You can install it to the GAC yourself with gacutil.exe. It can store different versions of the same assembly. It can store only strongly-named assemblies. The GAC is a place on the machine to share assemblies for multiple applications. If it’s a strongly-named assembly, check the Global Assembly Cache (GAC). If a different version is loaded, a FileLoadException will be thrown, unless it’s a strongly-named assembly that can be loaded in several versions side-by-side. Here binding redirects come into play (more on that later).

That configuration file name will be (after the build). Here’s the actual logic executed (see Microsoft’s documentation for elaboration):ĭetermine the version of the assembly that needs to load according to configuration files ( app.config or web.config). When the CLR needs to load an assembly, the logic is actually a bit more complicated than looking in the Bin folder. But when entering the Add method, the CLR tries to resolve the Calculator type, figures out it’s in a referenced assembly Lib1 and then tries to load that assembly. When entering Main method, the Lib1 assembly isn’t loaded yet. MyStartup uses some classes from the Lib1 assembly. Let’s say that we have a simple Console application called MyStartup that referenced another project called Lib1. This is also called binding to the assembly. It then loads that assembly into the process. At runtime, when you use a type from a referenced project for the first time, the CLR looks in the application directory for the DLL file with the same name and version it expects. It will usually be Bin\Debug or Bin\Release. When you reference a project from another project, at build time, the referenced project’s DLL or EXE are copied to the Bin folder of the startup project. MyStartup.dll is the startup project here: NET Framework project (Modules and Assemblies are the same for all our intents and purposes). Here are the modules loaded for a simple “Hello World”. It will load assemblies lazily, only when it needs to call a method or use a type from that assembly. Afterward, the process is going to load other assemblies at runtime according to its need.

It’s going to be the first assembly loaded except for. When starting a process or hitting F5 in Visual Studio, your startup project assembly is going to be executed. Each assembly can contain multiple Modules, but in practice, we’ll almost always have one module in an assembly, which will have the same name as the assembly. Each project in your Visual Studio solution is compiled into an assembly. Let’s start with some basic terms around a.

You’ll see how to debug these types of problems, see assembly binding logs (fusion logs), and see some ways to resolve conflicts. You’ll understand which library version was loaded, what happens when there are several versions available, and why problems sometimes occur due to version conflicts. In this article, you’ll see how and when a. The best way to deal with such issues is to understand how the mechanism works internally. With a large enough web of dependencies, you’ll eventually get into conflicts or hard situations. These libraries depend on other popular libraries and there are a lot of shared dependencies. We are constantly dealing with libraries and NuGet packages. NET developer needs to understand how the.
