.Net Application Performing Slow
Microsoft Professional Advisory Services is a support option that provides short-term, proactive, consultative support beyond break-fix product maintenance needs. This includes working with the same technician for assistance with issues like product migration, code review, or new program development and is a remote, phone-based support option. This service is typically used for shorter engagements, and is designed for developers and IT professionals who do not require the traditional onsite consulting or sustained account management services that are available from other Microsoft support options.
For additional information on Microsoft Advisory Services, including on how to engage, refer to this Microsoft web page:

Customers often complain about the .NET application's performance issues. Like, slow startup, hang, taking too long to perform tasks etc…
Scoping questions- What version of CLR the app is on, check the latest.
- Is this a 32 bit or a 64 bit application?
- What type of application? Generally any network based, database related, graphics related app would run slow due to excessive data transfer and data rendering.
- If issue is to do with application slow startup, checking on how the app's assemblies are installed. Typically using the ngen.exe tool to ngen the assemblies resolve app startup issues.
Below is a list of self-help resources or this scenario. These resources may also be used by Microsoft Support Engineers during an Advisory Services engagement.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
