Featured Reviews

MANUEL VALDIVIA - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.
Muhammad Qasim - PeerSpot reviewer
Solutions Architect at Diyar United Company
Has enabled building responsive multi-threaded applications while supporting rapid deployment workflows
Microsoft .NET Framework has already made significant improvements by becoming open source. Many developers are contributing to Microsoft .NET Framework, not just Microsoft itself. They have ported it to many platforms and allow a healthy ecosystem of open source tools. They have moved from Visual SourceSafe to supporting Git with Microsoft Visual Studio. Their IDE, Visual Studio Code, is open source and multi-platform. There are many third-party tools available, including AI-based tools such as Cursor and Bolt, which are forks of Visual Studio Code. Based on my understanding, I don't have any suggestions for improvement as they are already doing an excellent job.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a scalable solution...The setup is easy."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"Performance-wise, this solution is really good."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"The documentation, performance, stability and scalability of the tool are valuable."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"Setup is very easy; we had proper documentation for setup, so it didn't take much time, and setup takes a maximum of two or three hours and I can set up the complete application."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"The most valuable features for us are web frameworks like MVC, Web API, and WCS."
"My advice is that C# is a very rich language with lots of advanced facilities, which makes it easier to develop by not being too complex."
"It facilitates running Windows business applications and leveraging enterprise application development."
"The technology is very scalable and accessible to use."
"Microsoft .NET Framework has introduced many new features, making the technology very vast."
"As we are a software company, we find that accessing resources using this technology is easier compared to the others."
"The .NET Framework simplified operations dealing with the allocation and deallocation of memory spaces and the additional processing resources."
"Overall, we are very satisfied with using this platform for application development."
 

Cons

"The images and size of the containers are too big and I think that they should be more lightweight."
"My biggest complaint about this product is the price."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"The product's features are not being upgraded or enhanced by the vendor"
"They are expensive and not worth the money we are spending on them."
"I find the installation configuration is quite difficult compared to other solutions."
"Technical support is good but they could have a better response time."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"The solution could improve by optimizing the memory for better performance."
"Microsoft .NET Framework has a steep learning curve, which could be improved."
"I would like more web integration."
"Microsoft has its own product called Blazor, but I don't think it's quite as powerful yet as React or Angular. That's an area for improvement."
"Improvements are needed in .NET development, particularly in a backend scenario."
"The significant challenge is that you need an enterprise-level company to maintain software in Microsoft .NET Framework with a proper structure."
"The integration with DevOps tools, such as Azure DevOps, Jira, and GitLab, would be a valuable addition."
"Scalability is a bit messy so we're forced to use different solutions for different clustering."
 

Pricing and Cost Advice

"The solution is expensive."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"The solution is expensive."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The price is very high and it's the main reason that we are searching for alternatives."
"This product is more expensive than competing products."
"For the moment I can only give the product a rating of five out of ten since only some of the customers will be satisfied, those that have the financial resources for hosting a platform on Windows Server."
"In the interim, there's no need to purchase videos for viewing. Microsoft has made significant moves in the .NET space, starting with their response in Visual Studio Code and now providing Visual Studio entirely for free. This is a notable shift from the past when we used to pay substantial amounts for technical subscriptions. Previously, a group of ten developers could cost several thousand dollars annually for licensing. However, the current trend is to offer these tools for free to maintain their dominance in the developer market. The market dynamics have changed, and now developers can freely download Visual Studio, making it a preferred choice over other paid options."
"The product is not expensive."
"The Microsoft .NET Framework is free of charge, without licensing cost."
"The solution is a bit costly when compared to open source products or open gear licenses."
"Microsoft .NET Framework is a free, open-source solution."
"We have an annual license, and we pay extra for extended support."
"The pricing could be cheaper."
