I am receiving: "Recompilation limit of 100 reached. HostingEnvironment caused shutdown" in Event l

Unfortunately, this is caused by .NET framework. It restarts the application automatically, after a specified number of compilations is reached, e.g. if you edited some code files, etc. This value can be set in web.config file (by default it is 100):

 <compilation debug="false" numRecompilesBeforeAppRestart="100">
