Resource files in Dot Net

Resource files are typically used to store any resources in your Dot Net application. Resource file allows you to store images, icons, audio, files, strings and other types of resources. Of cause it is not mandatory to keep them inside a resource file. But when it comes to localization it is recommended to work with the resource file.

localization

Which means based on the user's language and culture change the application and the resources.

How to archive localization with resources?

Seems to be an impossible task. But to make the impossible possible, Dot Net provides you a special assembly called "Satellite Assembly"

Satellite assemblies are assemblies that containing resources specific to a given language and culture. Using satellite assemblies, you can place the resources for different languages in different assemblies, and the correct assembly is loaded into memory only if the user selects to view the application in that language. By definition, satellite assemblies can only contain resources. They cannot contain any executable code.

In general, assemblies should contain culture-neutral resources. If you want to localize your assembly (for example use different strings for different locales) you should use satellite assemblies.

Use the Assembly Linker (Al.exe) to compile .resources files into satellite assemblies. Al.exe creates an assembly from the .resources files that you specify.

This is how output looks after you compile solution (reference),

Simple Demo 

Create a Dot Net Class Library Project (reference)
Add a Resource File (reference)
Store a single string named HelloString whose value is "Hello!".


Create Localized Version of the Resource File (reference)


Build the Solution and check out the output folder


you can see the resources for different languages in different assemblies under corresponding language folder, and the correct assembly is loaded into memory only if the user selects to view the application in that language.


May the force be with you!

SSAS: The Sort Order Specified For Distinct Count Records Is Incorrect.

Symptoms During a processing time of a cube that contains a distinct count measure, the process fails with the following error message: The sort order specified for distinct count records is incorrect Cause This is most likely caused by different sort order used on the data warehouse data set and the analysis service database data set. Resolution Modify the sort order of the data warehouse data set so that it will match with the analysis service database data set. Into the Depth  Navigate to the analysis database and start to process the desired database. When the processing begins, the Process progress window will pop up. Wait till the process gets failed. After the process failed, find the failing measure group and expand to the last node where you can see an SQL query. Double click on the query and view the details. This query gives you the exact order by the column which caused you this trouble.  Execute the query using the data warehouse datab...

Dynamic Assembly in C#

Static Assembly Vs Dynamic Assembly Static Assemblies are those assemblies which are stored on the disk permanently as a file or set of files. Since these assemblies are stored in the disk, those are only loaded when CLR requests.  These are the assemblies we are dealing with daily. Assemblies that I'm going to talk about today bit different. It completely opposite of the Static Assemblies. Those Assemblies are not stored on the disk before execution. When an application requires any type, which references from these assemblies, DOT NET will create these Assemblies at the runtime so that it will directly load into the memory. Why is it important ? Like I mentioned, this is not something we do very often. It is not all about how important it is. Personally, I think it is better to know this kind of hidden language features. More you play with this more you learn. I found cool stuff I can do with this. Hope it will be same for you as well. This is an old feature. How ...

global.json file

  Symptoms Suddenly you get build errors in your build pipeline which perfectly builds in your local machine 🤔🤔🤔 Cause Most likely the root cause is .NET SDK versions. Your local machine builds on a different SDK and the pipeline builds on a different SDK. Resolution The ideal way of solving this is to force everyone to use one define .Net SDK. Regardless of whether it is a developer or CI pipeline. Simply to make this happen .NET  provides you a file called "global.json". The global.json file allows you to define which .NET SDK version is used when you run .NET CLI commands. Selecting the .NET SDK version is independent from specifying the runtime version a project targets. For information about specifying the runtime version instead of the SDK version, see Target frameworks . If you always want to use the latest SDK version that is installed on your machine, no global.json file is needed. Into the Depth The sample global.json file looks like the below, {    ...
