Slow startup with IIS Express

Question

I have a problem with my MVC application and startup.

Every time I make a change and one the app its take a long time to start up.

I have about 100 lines with ''iisexpress.exe' (CLR v4.0.30319:'

Do I have to start iisexpress every time I run my application?

Answer 1

I found significant improvement after disabling logging.

Locate the IIS config for your project or machine, typically found in:

• %userprofile%\documents\iisexpress\config\applicationhost.config
• .\.vs\config\applicationhost.config
• VS2019: $(solutionDir)\.vs\{projectName}\config\applicationhost.config

And comment out or delete the following two nodes (found somewhere in the document)

<add name="HttpLoggingModule" image="%IIS_BIN%\loghttp.dll" /> <add name="HttpLoggingModule" lockItem="true" /> 

Answer 2

I had this same problem, tested with VS2010 and VS2015. Symptom: VS was quick, compiled, loaded symbols and opened browser within a second but then browser just hung for 5 to 20 minutes. My projects are huge but my laptop is 16GB RAM, i7 and SSD so definitely not a size problem. I tried all the answers on this question and also here Visual Studio debugging/loading very slow.

In the end I found the solution here https://social.msdn.microsoft.com/Forums/en-US/394f3100-bac2-4b1c-8f8c-731226b905d4/painfully-slow-starting-a-web-application-in-visual-studio?forum=visualstudiogeneral

Exclude the directory "C:\Windows\Microsoft.NET\Framework" from antivirus scanning

Hopefully this will save someone else so much wasted time :)
