Image that if we have one application continues to log down user’s login information (format) as below under the share point (network drive): 2022-05-06 06:31:51.666,Ben,Login successfully. 2022-05-06 06:35:10.16,Andy,Account locked.

Microservice was conventional practice nowadays. The application(s) connected to internal or external APIs for exchange data of common ways. But we might suddenly occurred below error since we try to fire http connection through the help of .NET HttpClient:

Locate In Network Remote Drive — Suppose we got very simple Powershell script (TestRemote.ps1) over remote path: {REMOTE_ADDRESS}\{REMOTE_FOLDER} for execute: #TestRemote.ps1 Write-Host "Testing." We could expect that to invoke the script through below command: \\{REMOTE_ADDRESS}\{REMOTE_FOLDER}\TestRemote.ps1 But somehow we might encounter below error: “UnauthorizedAccess”.

Take MSSQL as example — Suppose we have table “ProductionWork” that record the manufacture meta data for the production process. DECLARE @ProductionWork TABLE ( WorkOrder varchar(20), -- store work order number Material varchar(15), Quantity smallint, Multiplier smallint -- multiplier for the quantity ); -- create some sample data INSERT INTO @ProductionWork VALUES ('WO#1', 'M1', 9, 2), ('WO#1', 'M2'…

Take BizTalk Server 2020 as example — Some how we might need to interactive with database in the orchestration flow (under BizTalk) for some reasons: write the data back after some specific action or business rule. The story will guide the way step by step. The the very beginning of starting operating our “Message” inside the orchestration…

Using framework Moq as example — We have a story that talked about how to mock the object(s)/service(s) [Test Double] for separating depended-on component (DOC) from data source (database…) , third-party’s API…etc. Then we could focus on target function(s) what we need to verify. But sometimes we would having hyper testing scenario that our target testing…

.NET CORE 3.1 Application — Case study We have an application that will invoke web API (pull data from database) and return the data set to client(s) as above diagram. The system all works fine but some day went to OOM (Out Of Memory) issue suddenly:

Azure Functions 2.x, Function runtime V3.2 — Configuration The common way that we apply our custom setting under azure function via local.settings.json (for development) as example below: ``` local.settings.json { "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "UseDevelopmentStorage=true", "FUNCTIONS_WORKER_RUNTIME": "dotnet", "BYOB_TokenMap": "D:\\Temp", "Uri": "http://xxxxxx/api/getxxxxx" } }

For multiple criteria conditions — Suppose we have country name and country code mapping table as below: We would like to provide a service that accept multiple country code as input and return the correspond country information back. For instance, if we have Country Code [297, 355, 1–268] for the criteria and we would…
