Where can I modify the detailed C # compiler optimization settings in Visual Studio?

In Visual Studio C/C++ projects, you can easily modify the optimization settings of the compiler in the “Property Page | C/C++ | Optimization”. For example, we can provide different optimizations Levels, such as /O2 and /O3, and advanced optimizations, such as “Ignore Frame Pointer”.

However, I cannot simply find the corresponding UI in the C# project of Visual Studio. All I can find is to turn off optimization: the “optimize code” checkbox is what I have.

Can C# users control the optimization of the detailed compiler, such as C/C++? Do I have to provide compiler options on the command line?

Most optimizations of C# code are performed at the JIT compiler level rather than the C# compiler. Basically there are no detailed settings available in C or C.

You can adjust the runtime Some of the performance-related elements, such as GC strategy, but not many.

When I build benchmarks etc. from the command line, I tend to use something like this:

< /p>

csc /o+ /debug- Test.cs

(I believe I have seen the existence of matching pdb files have an impact on performance, maybe in terms of the cost of throwing exceptions, So the debug switch… but I may be wrong.)

Edit: If you want to see every difference in optimization, there is a way to prove interesting:

>Use and Compile the same code without optimization>Use ildasm or Reflector in IL mode to see the difference>Manually (using ilasm) apply the same changes one by one and measure the number of each change

Most of the optimization of C# code is in JIT Compiler level instead of C# compiler. Basically there are no detailed settings available in C or C.

You can adjust some performance-related elements at runtime, such as GC strategy, But not a lot.

When I build benchmarks etc. from the command line, I tend to use something like this:

csc /o+ /debug- Test.cs

(I believe I have seen the existence of matching pdb files have an impact on performance, maybe in terms of the cost of throwing exceptions, so the debugging switch… but I may be wrong. )
