Roslyn: OutOfMemoryException in CodeAnalysis

[ogazioglu]

I am currently developing a wide solution, which contains 23 projects.
One of them is .net 4.7.1, five of them are .net standard 2.0 and the rest of them are .net core 2.2
There are 3 microservices, which contains 4 project each and uses entity framework core 2.2. One of them has 492 migration files.
Contracts is shared using local nuget server.

Visual studio has been crashing every day. Sometimes it's been happening a few times in a day. I suspect about migration file count.

Version Used: VS 15.9.11

Steps to Reproduce:

1. Install ReSharper 2019.1
2. Disable Rosylyn full solution analysis
3. Disable CodeLens for all languages
4. Open huge solutions including 20-25 projects.
5. Use more than 1 days or maybe less.

Expected Behavior:

No exception

Actual Behavior:

Application: devenv.exe
Framework Version: v4.0.30319
Description: The application requested process termination through System.Environment.FailFast(string message).
Message: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

@ogazioglu We are not able to properly investigate Out Of Memory exceptions through GitHub, since we need the information to be provided under the privacy policies of developercommunity.visualstudio.com. You can find information about collecting a heap dump for a crash at https://aka.ms/reportPerf, and can submit the information through the Report a Problem tool in Visual Studio so we can investigate it.

Thank you!
