Memory Leak in Blazor project

[Suriya-Murugan]

Hi Team,

We are facing when using C#(ASP.NET Core) library in blazor project. Trying to read text file, using stream reader.

We have attached sample for reference.

• Try running the sample.
• We have used StreamReader which load text file.
• For each iteration(looping), Memory gets increased and not released.

Please check this and share the details.

@Suriya-Murugan thanks for contacting us.

This is not a memory leak.

Seems like you have the debugger attached and its likely a debug build.

In addition to that, it seems that you are still holding a reference in the stack to the stream you seem to want to collect. Finally, the call to GC.Collect you have in your code is not effective because you are reading a large document into a string which is going to be allocated on the Large Object Heap.

Regular collections won't free space in the LOH, to force that you need to do something like GC.Collect(2, GCCollectionMode.Forced);

If you null out the reference to the stream and trigger a full collection you'll observe the memory go down and become stable.

Hope this helps
