The result is of these actions is, that OpenAI is now a “first class citizen” on Azure. So - for the average Microsoft/.NET developer this opens up a wonderful toolbox and the first steps are really easy. Be ...

How to fix: 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine

In our product we can interact with different datasource and one of these datasources was a Microsoft Access DB connected via OLEDB .

Resource type is not supported in this subscription

I was playing around with some Visual Studio Tooling and noticed this error during the creation of a “Azure Container Apps”-app: Resource type is not supported in this subscription Solution The solution is quite strange at first, but in the super configurable world of Azure it makes sense: You need to activate the Resource provider for this feature on your subscription. For Azure ...

Creating a circuit breaker health check using Polly CircuitBreaker

Finally! After months of not writing a blog post, here it is: A GitHub Issue on the ASP.NET Core Docs points me to Polly CircuitBreaker. Which is really great. Before that, I didn't even know that circuit breakers is a term in the software industry. Actually, I implemented mechanisms that work like that but never called them circuit breakers. Maybe that's the curse of never having ...

Use ASP.NET Core and React with Vite.js

The CRA Problem In my previous post I showed a simple setup with ASP.NET Core & React. The React part was created with the “CRA”-Tooling, which is kind of problematic. The “new” state of the art React tooling seems to be vite.js - so let’s take a look how to use this. Step for Step Step 1: Create a “normal” ASP.NET Core project (I like the ASP.NET Core MVC template, but feel free to use ...

Use ASP.NET Core & React togehter

The ASP.NET Core React template Visual Studio (at least VS 2019 and the newer 2022) ships with a ASP.NET Core React template, which is “ok-ish”, but has some really bad problems: The React part of this template is scaffolded via “CRA” (which seems to be problematic as well, but is not the point of this post) and uses JavaScript instead of TypeScript. Another huge pain point (from my ...

Your URL is flagged as malware/phishing, now what?

Problem On my last day in 2022 - Friday, 23. December, I received a support ticket from one customer, that our software seems to be offline and it looks like that our servers are not responding. I checked our monitoring and the server side of the customer and everything was fine. My first thought: Maybe a misconfiguration on the customer side, but after a remote support session with ...

SQLLocalDb update

Short Intro SqlLocalDb is a “developer” SQL server, without the “full” SQL Server (Express) installation.

Windows Terminal, PowerShell, oh-my-posh, and Winget

Azure DevOps & Azure Service Connection

Today I needed to setup a new release pipeline on our Azure DevOps Server installation to deploy some stuff automatically to Azure. The UI (at least on the Azure DevOps Server 2020 (!)) is not really clear about how to connect those two worlds, and thats why I’m writing this short blogpost. First - under project settings - add a new service connection. Use the Azure Resource Manager ...

'error MSB8011: Failed to register output.' & UTF8-BOM files

Be aware: I’m not a C developer and this might be an “obvious” problem, but it took me a while to resolve this issue. In our product we have very few C projects. We use these projects for very special Microsoft Office COM stuff and because of COM we need to register some components during the build. Everything worked as expected, but we renamed a few files and our build broke with: ...

ASP.NET Core on .NET 7.0 - Output caching

Finally, Microsoft added output caching to the ASP.NET Core 7.0 preview 6. Output caching is a middleware that caches the entire output of an endpoint instead of executing the endpoint every time it gets requested. This will make your endpoints a lot faster. This kind of caching is useful for APIs that provide data that don't change a lot or that gets accessed pretty frequently. It ...

How to run a Azure App Service WebJob with parameters

We are using WebJobs in our Azure App Service deployment and they are pretty “easy” for the most part. Just register a WebJobs or deploy your .exe/.bat/.ps1/... under the \site\wwwroot\app_data\Jobs\triggered folder and it should execute as described in the settings.job . If you put any executable in this WebJob folder, it will be executed as planned. Problem: Parameters If ...

ASP.​NET Core on .NET 7.0 - File upload and streams using Minimal API

It seems the Minimal API that got introduced in ASP.NET Core 6.0 will now be finished in 7.0. One feature that was heavily missed in 6.0 was the File Upload, as well as the possibility to read the request body as a stream. Let's have a look how this would look alike. The Minimal API Creating endpoints using the Minimal API is great for beginners, or to create small endpoints like for ...

How to use IE proxy settings with HttpClient

Internet Explorer is - mostly - dead, but some weird settings are still around and “attached” to the old world, at least on Windows 10. If your system administrator uses some advanced proxy settings (e.g. a PAC-file), those will be attached to the users IE setting. If you want to use this with a HttpClient you need to code something like this: string target ...

ASP.NET Core on .NET 7.0 - Roadmap, preview 1 and file upload in minimal APIs

This is thee chance to have the first glimpse at ASP.NET Core 7.0 which will be released beginning of ...
